Using Intelligent Input Terminals
Intelligent terminals [1], [2], [3], [4], [5], [6 ], [7], and [8] are identical, programmable inputs 
for general use. The input circuits can use the in verter’s internal (isolated) +24V field supply 
(P24) to power the inputs. The input circuits conne ct internally to [PLC] as a common point. To 
use the internal supply to power the inputs, use the jumper as shown. Remove the jumper to use 
an external supply, or to interface to a PLC syst em (or other) that has solid state outputs. If you 
use an external supply or PLC system, its power  return must connect to the [PLC] terminal on 
the inverter to complete the input circuit.
Input Wiring 
ExamplesThe following four input configurations are availabl e to interface the inverter inputs to switches 
or the outputs of anothe r system, such as a PLC.

Forward Run/
Stop and Reverse 
Run/Stop 
Commands   When you input the Run command via the dedicate d terminal [FW], the inverter executes the 
Forward Run command (high) or Stop command  (low). When you input the Run command via 
the programmable terminal [RV], the inverter executes the Reverse Run command (high) or 
Stop command (low). Note the following:
 When the Forward Run and Reverse Run commands  are active at the same time, the inverter 
enters the Stop Mode.
 When a terminal associated with either [F W] or [RV] function is configured for normally 
closed , the motor starts rotation when that terminal  is disconnected or otherwise has no input 
voltage.
 The parameter F004, Keypad Run Key Routing, determines whethe r the single Run key 
issues a Run FWD command or Run REV command. However, it has no effect on the [FW] 
and [RV] input te rminal operation.
 
WARNING:  If the power is turned ON and the Run  command is already active, the motor 
starts rotation and is dangerous! Before turning power ON, confirm that the external Run 
command is not active.
Multi-Speed 
Select, Binary 
Encoded   The inverter can store up to 16 different fixed target frequencies (speeds) in parameters A020 
to A035. Binary inputs select the speed through fo ur of the intelligent terminals configured as 
binary-encoded inputs CF1 to CF4 per the table.  These can be any of the eight inputs, and in 
any order. You can use fewer inputs if  you need eight or fewer speeds.   
NOTE: When choosing a subset of speeds to use, always start at the top of the table, and with 
the least-significant bit: CF1, CF2, etc.

The example with eight speeds in the figure  below shows how input switches configured for 
CF1 – CF3 functions can change the motor speed in real time. 
Multi-speed Override Feature - The multi-speed function can  selectively override the 
external analog speed reference input. When  the Frequency Source Setting parameter 
A001=01, the control terminal inputs determin e the output frequency. At the same time, the 
inverter can use multi-speed sele ct for output frequency if one or more intelligent inputs are 
configured as a CF type (CF1 to CF4). When all  CF input(s) are OFF, the control terminal input 
determines the output fre quency normally. When one or more CF input(s) are ON, then the 
corresponding multi-speed setting (see the ta ble above) overrides and becomes the output 
frequency.
When programming the multi-speed settings, be su re to press the Store key each time and then 
set the next multi-speed setting. No te that when the Store key is not pressed, no data will be set.
When a multi-speed setting more  than 50Hz(60Hz) is to be set, it is necessary to program the 
maximum frequency A004 high enough to allow that speed.
While using the multi-speed capability, you can monitor the output frequency with monitor 
function D001 during each segment of a multi-speed operation.
There are two ways to program the speeds into the registers A020 to A035:
1. Standard keypad programming:
a.Select each parame ter A020 to A035.
b. Press the   key to view the parameter value.
c. Use the    and   keys to edit the value.
d. Use the   key to save the data to memory.
2. Programming using the CF switches:
a.Turn the Run command OFF (Stop Mode).
b. Turn inputs ON to select desired Multi-spee d. Display the value of F001 on the digital 
operator.
c. Set the desired output frequency by pressing the   and   keys.
d. Press the   key once to store the set frequenc y. When this occurs, F001 indicates the 
output frequency of the selected Multi-speed.
e. Press the   key once to confirm that the indi cation is the same as the set frequency.
f. Repeat operations in 2. a) to 2. e) to set the frequency of other Multi-speeds. It can be set 
also by parameters A020 to A035 in the first procedure 1. a) to 1. d).

Multi-Speed 
Select, Bit-level  The Bit-level method of speed control 
uses up to seven intelligent inputs to 
select from up to ei ght speeds. Since the 
all-switches-OFF combination selects 
the first speed, you only need N–1 
switches to select N speeds. With Bit-
level speed control, only one input is 
normally active at a time. If multiple 
switches are ON, the lower numbered 
input takes precedence (determines the 
speed). The table and figure below 
show how the input combinations work.

Jogging 
Command   The Jog input [JG] is used to command the 
motor to rotate slowly in small increments 
for manual operation. The speed is limited 
to 10 Hz. The frequency for the jogging 
operation is set by parameter A038. Jogging 
does not use an acceleration ramp. There-
fore setting the jogging frequency A038 too 
high will cause inverter tripping.
A jog command may arrive while the motor 
is running. You can program the inverter to 
either ignore or respond to a jog command 
in this case by using function A039. The 
type of deceleration used to end a motor jog 
is also selectable by programming function  A039. Six jog mode options are defined below:
In the left example diagram below, the Jog comm and is ignored. In the right example diagram, 
a jog command interrupts a Ru n mode operation. However, if the Jog command turns ON 
before the [FW] or [RV]  terminal turns ON, the inverter output turns OFF. 
Note the following:
 Jogging is not performed when the value of A 038 jogging frequency is smaller than the start 
frequency B082 or the
 value is 0 Hz.
 Be sure to turn ON [FW] or [RV]  after the [JG] input turns ON for a jog operation.
 When setting A039 to 02 or 05, you must  also set the DC braking parameters.

External Signal 
for DC Injection 
Braking   When the terminal [DB] is turned ON, the 
DC braking [DB] feature is enabled 
(regardless of A051 setting). Set the follow-
ing parameters when the external DC 
braking terminal is to be used:
 A053 – DC braking delay time setting.  The range 0.0 to 5.0 seconds.
 A054 – DC braking force setting. The  range is 0 to 100% for models -004xxx 
to -1500xxx; 0 to 35% for models 
-1850xxx to -4000xxx. 
The scenarios to the right help show how 
DC braking works in various situations. 
1. Scenario 1 – The [FW] Run or [RV] 
Run terminal is ON. When the [DB] 
terminal turns ON, DC braking is 
applied. When the [DB] terminal turns 
OFF again, the inverter output ramps to 
the previous frequency.
2. Scenario 2 – The Run command is 
applied from the operator keypad. When 
the [DB] terminal turns ON, DC braking 
is applied. When the [DB] terminal 
turns OFF again, the inverter output 
remains OFF.
3. Scenario 3 – The Run command is 
applied from the operator keypad. When 
the [DB] terminal turns ON, DC braking 
is applied after th e delay time set by 
A053 expires. The motor is in a free-
running (coasting) condition during this 
delay time. When the [DB] terminal 
turns OFF again, the inverter output remains OFF.
Note the following:
 Do not use the [DB] input continuously or for a  long time when the DC braking force setting 
A054 is high (depends on the motor application).
 Do not use the [DB] feature for continuous or  high duty cycle as a holding brake. The [DB] 
input is designed to improve  stopping performance. Use a mechanical brake for holding a 
stop position.
Set Second or 
Third Motors   If you assign the [SET] or [SET3] functions to  an intelligent input terminal, you can select 
between two or three sets of motor parameters. You ma y assign one or both of these functions. 
These second and third parameters store alternate  sets of motor characteristics. When terminal 
[SET] or [SET3] is turned ON, the inverter will use the second or third set of parameters 
accordingly, generating the frequency output to  the motor. When changing the state of the 
[SET] or [SET3] input terminal,  the change will not take effect until the inverter is stopped.
When you turn ON the [SET] or [SET3] input, the inverter operates per the second or third set 
of parameters, respectively. When the terminal is  turned OFF, the output function returns to the 
original settings (first set of motor parameters). Refer to  “
Configuring the Inverter for Multiple 
Motors” on page 4–76 for details.
Note the following:
 If the terminal state is changed while the inverter is running, the invert er continues using the 
current set of parameters until the inverter is stopped.
 If both SET and SET3 are ON at the same time, SET prevails and the 2nd motor parameters  are in effect.
