6.3 Reset Function

When the safety function is activated, reset the safety option. Depending on the configuration, the following sources can reset the
safety option:

The 

[Reset]

 key on the LCP or the digital input of the drive.

The digital input on the safety option (DI2_A).

The reset signal via the safe fieldbus.

The automatic reset function.

Parameter 42-24 Restart Behavior

 determines whether the safety option restarts automatically or waits for a manual reset after the

safety function was activated:

Manual reset behavior - when the safety function is activated, the safety option requires a reset from a reset source before it can
run again.

Automatic reset behavior - when the safety function is activated, the safety option can run again when the condition that triggered
the safety function ceases. This behavior is only valid for the digital input where this reset behavior is defined. For instance, if an
external error occurs, a manual reset from the reset source is required regardless of the setting in 

parameter 42-24 Restart Behavior

.

For more information, read the description of 

parameter 42-31 Reset Source

 and its options in CHAPTER 7.1 PARAMETER LIST.

6.3.1 Reset Input (DI2)

If manual reset is configured, wire the DI2A reset input terminal to a 24 V DC via an NO switch. The manual reset can also be used to
reset external errors detected by the safety option.
