Introduction Geting Started 1–2 Introduction Main FeaturesCongratulations on your purchase of an SJ7002 Series Hitachi inverter! This inverter drive features state-of-the-art circuitry and components to provide high performance. The housing footprint is excep- tionally small, given the size of the corresponding motor. The Hitachi SJ700 2 product line includes more than twenty inverter models to cover motor sizes from 1/2 horsepower to 500 horsepower, in either 230 VAC or 480 VAC power input versions. The main features are: 200V Class and 400V Class inverters U.S. or European version available Sensorless vector control Regenerative braking circuit Different operator keypa ds available for RUN/ STOP control and setting parameters Built-in RS-422 commun ications interface to allow configuration from a PC and for field bus external modules Sixteen programmable speed levels Motor constants are programmable, or may be set via auto-tuning PID control adjusts motor speed automatically to maintain a process variable value The design of Hitachi inve rters overcomes many of the traditional trade-offs between speed, torque and efficiency. The performance characteristics are: High starting torque of 150% rating or greater Continuous operation at 100% rated torque within a 1:10 speed range (6/60 Hz / 5/50 Hz) without motor derating Models from 0.4–22kW (1/2 to 30hp) have built- in dynamic braking circuits Models from 0.4–11kW (1/2 to 15hp) have optional built-in dyna mic braking resistor Cooling fan has ON/OFF selection to provide longer life A full line of accessories from Hitachi is avail- able to complete your motor control application. These include: Digital remote operator keypad Expansion card for sensor feedback Braking resistors Radio noise filters Built-in CE compliance filters Additional factory I/O network interface cards (to be announced) Model SJ700-110HFUF2 (U.S. version) Model SJ700-037HFEF2(European version) Expansion Card - Encoder Input Phone: 800.894.0412
SJ7002 Inverter Getting Started 1–3 Digital Operator Interface ComponentsThe SJ7002 Series inverters have a detachable keypad (called a digital operator) on the front panel of the housing. The particular keypad that comes with the inverter depends on the country or continent corresponding to the particular model number. The standard digital operators occupy just part of the keypad recess in the panel. Therefore, the inverter comes with a snap-in panel filler plate that mount s below the keypad as shown. These detachable keypads can be mounted in a NEMA cabinet panel door cut-out, for example. Threaded metal inserts on the rear of the keypads facilitate this external mounting configura- tion. A short cable then connects the keypad unit to the connector in the inverter keypad recess. See Chapter 3 for information on how to install and use these keypads and cables. The digital operator / copy unit is optional, and occupies the entire keypa d recess when mounted. It has the additional capabili ty of reading (uploading) the parameter settings in the inverter into its memory. Then you can install the copy unit on another inverter and write (download) the parameter settings into that inverter. OEMs will find this unit particularly useful, as one can use a single copy unit to transfer parame- ter settings from one inverter to many. Other digital operator inte rfaces may be available from your Hitachi distributo r for particular industries or international markets. Contact your Hitachi distributor for further details.

SJ7002 Inverter Getting Started 1–9 The 400V models from –1850 to –4000HFU2/HFE2 (250 to 525 HP) include a DC reactor and ferrite core. Footnotes for the preceding tables and the table that follows: Note 1: The protection method conforms to JEM 1030. Note 2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When using other motors, care must be taken to prev ent the rated motor current (50/60 Hz) from exceeding the rated output current of the inverter. Note 3: The output voltage decreases as the main supply voltage decreases (except when using the AVR function). In any case, th e output voltage cannot exceed the input power supply voltage. Note 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the maximum allowable rotation speed. Note 5: When SLV is selected, please set the carrier frequency higher than 2.1 kHz. Note 6: At the rated voltage when using a Hitach i standard 3-phase, 4-pole motor (when selecting sensorless ve ctor control—SLV). Note 7: The braking torque via capaciti ve feedback is the average deceleration torque at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking torque. The average de cel torque varies with motor loss. This value decreases when operating beyond 50 Hz . If a large regenerative torque is required, the optional regenerative br aking resistor should be used. Note 8: The frequency command will equal the maxi mum frequency at 9.8V for input voltage 0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not satisfactory for your application, cont act your Hitachi sales representative. Note 9: The storage temperature refers to the short-term temperature during transport. Note 10: Conforms to the test method specified in JIS C0050 (1999). For the model types excluded in the standard spec ifications, contact your Hitachi sales representative. Note 11: NEMA 1 applies up to 22kW. An optional wire-entry conduit box is required for 0.4kW to 55kW models to meet NEMA 1 rating.
