Important
If the switch-off delay for stop category 1 is parameterized with a
value less than 150 ms, this value is rejected as a parameterization
error (error code 028x
hex
).
Two-channel
parameterization
Please note the following for two-channel parameterization:
Ensure that the values for the switch-off delay for stop category 1
are the same for both channels. This means that the time must
have the same value and the same value range.
5.3
Behavior of the outputs in the event of enabled
switch-off delay for stop category 1
Depending on the event that causes the outputs to be switched off, and on the
parameterization of the switch-off delay, the time until the outputs are actually switched
off can vary.

circuit, failure of the supply

WARNING
Delayed shutdown when using stop category 1
For stop category 1 please take into consideration the following:
–
The guaranteed shutdown time t
G
is extended by the parameterized switch-off delay.
