NOTE:
1.
Control circuit Terminals 1 to 33 are not arranged in order of terminal numbers; they are arranged as shown below.
Be sure to wire them correctly.

2. Do not use control circuit Terminals 13 and 14 at the same time. (The two signals will be added inside the Inverter if
they are input at the same time.
3. The maximum output current capacity of the +15 V/-15 V output from control circuit Terminals 15 and 33 is 20 mA.
4.
The multi-function analog output is a dedicated meter output for a frequency meter, ammeter, etc. Do not use this
output for Feedback Control or for any other control purpose. Use one of the optional analog monitors (AO-08 or
AO-012) for analog outputs to the control system.
5. Disable the Stall Prevention during deceleration (set constant L3-04 to 0) when using a Braking Resistor Unit. If this
user constant is not changed to disable Stall Prevention, the system may not stop during deceleration.
6. Enable protection for the internal DB resistor (model ERF) (set constant L8-01 to 1) when using an internal braking
resistor. The braking resistor will not be protected unless this setting is changed to enable protection.
7. DC Reactors to improve the input power factor can be connected as an option only to Inverters for 15 kW or less.
Remove the short bar from between
⊕
1 and
⊕
2 when connecting a DC Reactor.
8. There is no DC power supply input terminals for 200 V class Inverters of 30 to 75 kW and 400 V class Inverters of 55
to 160 kW, and DC power cannot be input to these Inverters.
