Alarm Signal

If an overcurrent, overvoltage, or some other error occurs, the inverter shuts off its output and gener-

ates an alarm signal. This is called a "Trip".

A trip state can be canceled by resetting the inverter, by which the alarm signal also turns OFF.

To reset the inverter, press the STOP/RESET key or input the reset terminal. However, you may not be

able to reset some trip factors by using these methods. In such case, cycle the power supply.

The [AL] function is assigned in the initial state to the contact c relay [CC-07] of AL1-AL0 and AL2-AL0.

You can set the output specifications of contacts a and b to output terminals 11-15, relay output termi-

nals 16A-16C, AL1-AL0, and AL2-AL0 individually.

Precautions for Correct Use

When an inverter outputs error by an interruption of its power supply, in some cases, changes

of wirings and contact selections may alleviate this symptom.
