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 speed command may be set by Voltage, Current or both.
3. When installing the DC Reactor, the Common Busbar between P1 and P2 must be removed.
4. 1 ~ 10 HP inverters have on-board braking circuit. Braking resistors are only included for 1 ~ 5 inverters.
15 ~ 30 HP inverters need optional braking unit and resistor for dynamic braking.
