Forced Operation Command

When the multi-function input terminal S1 (H1-01 = 3C (default setting)) is “closed”, the regenerative unit starts
operation. When the terminal S1 is “open”, the regenerative unit stops operation after the minimum operation time has
passed.

Note: When forced operation command is selected, use a sequence so that the operation commands of the regenerative unit and the

drive are input at the same time.

Stopping the Regenerative Unit for Faults in Peripheral Devices

If an external device fails or a fault occurs, the fault contact output on the regenerative unit is activated to stop operation.
To use an external fault, set H1- (terminal S1 to S8 function selection) to one of the values from

Table 4.5

When an external fault is input, EF is displayed on the digital operator.
The in EF is the number of the terminal where the external fault signal was input.

Example: If an external fault signal is input to the S3 terminal, EF3 is displayed.

Select the number to set for H1- according to the combination of the following three conditions:

• Use an input contact for a signal from the peripheral device.
• Use detection of an external fault.
• Stop operation (as the operation selection when an external fault is detected).
