7-1 Standard Specification List 7 Specifications *1. The applicable motor is a 3-phase standard motor. For using any other type, be sure that the rated current does not exceed that of the Inverter. *2. Output voltage decreases according to the level of the power supply voltage. *3. The braking torque at the time of capacitor feedback is an average deceleration torque at the shortest deceleration (when it stops from 50 Hz), not a continuous regeneration torque. Also, the average deceleration torque varies depending on the motor loss. The value is reduced in operation at over 50 Hz. Note that no braking resistor is built into the Inverter.
If you need a larger regenerative torque, use an optionally available braking resistor. *4. Protection method complies with JEM 1030. 7-3 Item Specifications Input signal Digital Operator signal Frequency settings Setting with the FREQ adjuster and the Increment/Decrement keys on the Digital Operator, variable resistance from 1 to 2 kΩ (2 W), 0 to 10 V DC (input impedance 10 kΩ), 4 to 20 mA (input impedance 250 Ω), communication through an RS-485 port (Modbus communication).
