Stop!
The controllers 48XX/49XX must only be separated from the mains when they are
inhibited or the motor is in standstill.
This also applies to the emergency-off function.
The function |n
act
| < C019 can be used for the mains switch-off logic.
The digital output terminal A4 is for automatic mains switch-off. The terminals sets
”low”, if the actual speed value is lower than the value set under C019. The
threshold can be set under C019 from 0 to 5000 rpm. For this application, the
setting must not exceed 2% n
