Application Precautions
Jog frequencies using FJOG and RJOG commands have the priority over other frequency references.
•
When both FJOG command and RJOG commands are ON for 500 ms or longer at the same time, the
•
Inverter stops according to the setting in b1-03 (stopping method selection).

Stopping the Inverter on External Device Faults (External Fault Function)

The external fault function activates the fault contact output and stops the Inverter operation. Using this func-
tion the inverter operation can be stopped on peripheral devices break down or other faults. The digital opera-
tor will display EFx (External fault [input terminal Sx]). The x in EFx shows the number of the terminal at
which the external fault signal is input. For example, if an external fault signal is input to terminal S3, EF3
will be displayed.
To use the external fault function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05 (Ter-
minal S3 to S7 function selection).
Select the value to be set in H1-01 to H1-05 from a combination of any of the following three conditions.

* 1. Sets the input level at which faults are detected. (NO contact: External fault when ON; NC contact: External fault when OFF).
* 2. Set the detection method to detect faults 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.
