The following table shows the relationship between the external fault conditions and the set value in H1- †† .
1. Sets the input level at which errors are detected. (NO contact: External error when ON; NC contact: External error when OFF).
2. Set the detection method to detect errors using either constant detection or detection during operation.
Constant detection: Detects while power is supplied to the Inverter.
Detection during operation: Detects only during Inverter operation.

Using the Timer Function
The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and
multi-function output terminals M1-M2, M3-M4, and M5-M6 can be used as timer function output terminals.
By setting the delay time, you can prevent chattering of the sensors and switches.
•
Set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7) to 18 (timer function input).
•
Set H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, and M5-M6 function selection) to
12 (timer function output).
