Note) Main Circuit Terminals Control Circuit Terminals.
1. The terminal configuration varies depend on the model number. Please refer to the ‘1.7 Power terminals’.
2. Analog output voltage is adjustable up to 12V.
3. Analog speed command may be set by Voltage, Current or both.
4. The Common Busbar between P1/L1 and P2/L2 must be removed before installing DC Reactor.
5. 1 ~ 10 HP inverters have built-in braking circuit. Braking resistors are only included for 1 ~ 5HP inverters.
15~30HP inverters have built-in DB unit. 15 ~ 100 HP inverters need optional braking unit and resistor.
