Each Check ✔ or Ex ✘ indicates whether the corresponding parameter(s ) can be edited. The Standard Parameters column below lists Low and High level access for some lock modes. These refer to the parameter tables throughout this chapter, each of which includes a column titled Run Mode Edit as shown to the right. The two marks (Check ✔ or Ex ✘) under the “Lo Hi” subtitle indicate whether Low-level and/or High-level access applies to each parameter as defi ned in the table below. In some lock modes, you can edit only F001 and the Multi-speed parameter group that includes A020, A220 , A320, A021–A035, and A038 (Jog). However, it does not include A 019, Multi-speed operation selection. The editing access to B031 itself is unique, and is spec ified in the right-most two columns below. NOTE: Since the software lock function B031 is al ways accessible when the motor is stopped, this feature is not the same as password protec tion used in other industrial control devices. NOTE: To disable parameter editing when using B 031 lock modes 00 and 01, assign the [SFT] function to one of the intelligent input terminals. See “Software Lock” on page 4–23.

SJ7002 Inverter Configuring Drive Parameters 3–39 Miscellaneous SettingsThe miscellaneous settin gs include scaling factors, initialization mode s, and others. This section covers some of th e most important settings you may need to configure. Function Display SettingsThe inverter has the (optional) capability to su ppress the display and editing of certain parame- ters. Use B037 to select the display options. The purpose of this feature is to hide particular secondary parameters that become unused or no t applicable based on more fundamental param- eter settings. For example, setting A001 = 01 configures the inverter to get its frequency command from the front keypad potentiometer. In th is case, the inverter will not use the analog inputs nor their adjustment paramete rs for an external frequency command. For example, you can set B037=01 to have the in verter suppress the displaying of all analog input parameters when A001=01, as shown in the first row of the following table. Func.

“B” Group: Fine-Tuning Functions Configuring Drive Parameters 3–42 Controlled Deceleration at Power Loss – When enabled, this feature permits the inverter to control final motor deceleration upon loss of inverter input power. First, you must make a wiring change to the inverter. See “ Optional Controlled Decel and Alarm at Power Loss” on page 4–4 for complete instructions including wiring and signal timing diagrams for using the controlled decelera tion at power loss feature. After making the wiring change, use function B050 to enable the feature. Use B051 to deter- mine the point at which a decaying DC bus voltage will trigger the cont rolled deceleration. Use parameter B054 to specify an initial step-wise deceleration at power loss, and B053 to specify the duration of the linear deceleration. During the controlled deceleration the inverter itself acts as a load to decelerate the motor. With either a high-inertia load or a short deceleration time (or both), it is possible that the inverter impedance will not be low enough to continue linear deceleration and avoid an over-voltage condition on the DC bus. Use parameter B052 to specify a threshold for the over-voltage. In this case, the inverter pauses deceleration (runs at constant speed). When the DC bus decays again below the threshold, linear deceleration resumes. The pause/re sume process will repeat as necessary until the DC bus energy is de pleted (under-voltage condition occurs). The case when setting B052 is lower than the inverter supply voltage has special consider- ations: If B052 Over-voltage Threshold During Power Loss is less than B051 DC Bus Voltage Trigger Level During Power Loss, the over-vo ltage threshold during power loss will be increased to the DC bus voltage trigger level wi th the stop level is applied. However, the parameter setting will not be changed. When B052 is less than the supply voltage (the rectified DC voltage or the AC voltage times square root of two), when power recovers the inverter will be in the LAD-stop state and cannot decelerate. (The Stop Command and frequency ch ange command are ignored until deceleration is complete.) be sure to set B052 higher than the standard supply voltage. A non-stop decelera tion function cannot be canceled until it is complete. To restart the inverter operations after power recovery, wait until the inverter stops. Then enter a Stop Command and then an operation command (FW, RV). Setting a higher value for B054 Initial Output Frequency Decrease During Power Loss results in an over-current trip due to sudden deceleration. Setting a lower value for B054 or larger value for B053 Decelera tion Time Setting During Powe r Loss results in under-voltage trip due to reduced regenerative energy. Non-stop deceleration at inst antaneous power failure (B050=01) has these characteristics: The nonstop deceleration at instantaneous power failure is the function making the inverter decelerate and stop the motor while maintaining the voltage below the overvoltage level (over-voltage threshold during power loss [b052]) when an instantaneous power failure occurs during the inverter operation. To use this function, remove the J51 connector cables from terminals R0 and T0, connect the main circuit terminals P and R0 to each other, and connect the main circuit terminals N and T0 to each other. Use 0.75 mm2 or heavier wires for the connections. B045 Torque limit LADSTOP enable OFF00Disable000000✘ ✔ Temporarily stops accel/decel ramps during torque limit.

SJ7002 Inverter Configuring Drive Parameters 3–43 If an instantaneous power failure has occurred while the inverter is operating the motor and the output voltage falls to the DC bus voltage trigger level dur ing power loss (b051) or less, the inverter reduces the output frequency by the initial output frequency decrease during power loss (b054) once, and then decelerates the motor for th e deceleration time setting during power loss (b053). If the voltage increases to an overvoltage le vel (exceeding the over-voltage threshold during power loss [b052]) because of regeneration, the in verter enters the LAD stop state (deceler- ate to stop) until the voltage falls below the overvoltage level. If the over-voltage threshold during power loss (B 052) is less than the DC bus voltage trigger level during power loss (B051), the over-voltage th reshold during power loss will be increased to the DC bus voltage trigger level during power loss when the stop level is applied. (However, the stored setting will not be changed.) And, in case B052 is lower than the supply voltage (equivalent to rectified DC voltage which is square root of 2 times the supply AC voltage), when power recovers while this function is activa ted, inverter will be in the LAD stop status and cannot decelerate. (Stop command and frequen cy change command are not accepted until deceleration is complete). Be sure to se t b052 higher than the normal supply voltage. Func.

“B” Group: Fine-Tuning Functions Configuring Drive Parameters 3–44 Window ComparatorsThe window comparator function controls digi tal outputs based on the comparison of analog input values to user-defined upper and lower limits. Miscellaneous FunctionsB083: Carrier frequency adjustment – The internal switching frequency of the inverter circuitry (also called the chopper frequency). It is called the carrier frequency because the lower AC output frequency of the inverter “rides” the carrier. The faint, high-pitched sound you hear when the inverter is in Run Mode is characteristic of switching power supplies in general. The carrier frequency is adjustable fr om 500 Hz to 15 kHz (the upper limit varies, depending on the inverter rating) . The audible sound decreases at the higher frequencies, but RFI noise and leakage current may be increased. Refer to the specification derating curves in Chapter 1 to determine the maximum allowable carrier frequency setting for your particular inverter and environmental conditions. NOTE: When the inverter is in sensorless vector mode, use B083 to set the carrier frequency greater than 2.1 kHz for proper operation. NOTE: The carrier frequency setting must stay within specified limits for inverter-motor applications that must comply with particular regulatory agen cies. For example, a European CE-approved application requires the inverter carrier to be less than 5 kHz. Func.

SJ7002 Inverter Configuring Drive Parameters 3–45 B084, B085: Initialization codes – These functions allow you to restore the factory default settings. Please refer to “ Restoring Factory Default Settings” on page 6–16. B086: Frequency display scaling – You can convert the output frequency monitor on D001 to a scaled number (e ngineering units) monitore d at function D007. For example, the motor may run a conveyor that is monitored in fe et per minute. Use this formula: B091/B088: Stop Mode / Rest art Mode Configuration – You can configure how the inverter performs a standard stop (each time Run FWD an d REV signals turn OFF). Setting B091 deter- mines whether the inverter will control the deceleration, or whet her it will perform a free-run stop (coast to a stop). When usi ng the free-run stop selection, it is imperative to also configure how you want the inverter to resume control of motor speed. Setting B088 determines whether the inverter will ensure the motor always resu mes at 0 Hz, or whether the motor resumes from its current coasting speed (also called frequency matching). The Run command may turn OFF briefly, allowing the motor to coast to a slow er speed from which normal operation can resume. In most applications a cont rolled deceleration is desirable, corresponding to B091=00. However, applications such as HVAC fan contro l will often use a free-run stop (B091=01). This practice decreases dynamic stre ss on system components, prolongin g system life. In this case, you will typically set B088=01 in order to resume from the current speed after a free-run stop (see diagram below, right). Note that using the default setting, B088=00, can cause trip events when the inverter attempts to force the load quickly to zero speed.

“B” Group: Fine-Tuning Functions Configuring Drive Parameters 3–46 NOTE: Other events can cause (or be configured to cause) a free-run stop, such as power loss (see “ Automatic Restart Mode and Phase Loss” on page 3–30), and inverter trip events in general (see “ Miscellaneous Functions” on page 3–62). If all free-run stop behavior is impor- tant to your applicat ion (such as HVAC), be sure to configure each event accordingly. Some additional parameters further configure all instances of a free-run stop. Parameter B003, Retry Wait Time Before Motor Restart, sets the minimum time the inverter will free-run. For example, if B003 = 4 seconds (and B091=01) an d the cause of the free-run stop lasts 10 seconds, the inverter will free -run (coast) for a total of 14 seconds before driving the motor again.

SJ7002 Inverter Configuring Drive Parameters 3–47 B090: Dynamic braking usage ratio – This parameter limits the amount of time the inverter can use the dynamic braking accessory device with out entering the Trip Mode. Please refer to “ Dynamic Braking” on page 5–6 for more information on dynamic braking accessories. NOTE: When cooling fan control is enabled (B092=01) the inverter always turns the fan ON for five minutes immediately after powerup. This will cool the inverter in case the inverter / motor is still warm from prior running before a short power outage. Free-setting V/f PatternThe free-setting V/f inverter mode of operation uses voltage and frequency parameter pairs to define seven points on a V/f graph. This provides a way to define a multi-segment V/f curve that best suits your application. The frequency settings do require that F1 ≤ F2 ≤ F3 ≤ F4 ≤ F5 ≤ F6 ≤ F7; their values must have this ascending order relationship. To satisfy this criterion during initial parameter editing, set F7 (B112) and work backwards when setting th ese values, since the defaults are all 0 Hz. However, the voltages V1 to V7 may either in crease or decrease from one to the next. There- fore, you may set these parameters in any order.
