Description
If parameter 31.32 Emergency ramp supervision
this parameter defines the maximum time an emergency stop
(mode Off1 or Off3) is allowed to take. If the motor has not
stopped when the time elapses, the drive trips on
Emergency ramp failed, sets bit 8 of
2, and coasts to a stop.
If 31.32 is set to a value other than 0%, this parameter
defines a delay between the receipt of the emergency stop
command and the activation of the supervision. It is
recommended to specify a short delay to allow the speed
change rate to stabilize.
Maximum ramp-down time, or supervision activation delay.
Temporarily suppresses auxiliary fan faults.
Certain drive types (especially those protected to IP55) have
an auxiliary fan built into the front cover as standard. If the fan
is sticking or disconnected, the control program generates a
fault (5081 Auxiliary fan
If it is necessary to operate the drive without the front cover
(for example, during commissioning), this parameter can be
activated to temporarily generate a warning
fan missing) instead of the fault.
Notes:
• The parameter must be activated within 2 minutes of drive
reboot (either by cycling the power or by parameter 96.08).
• The parameter will be in effect until the auxiliary fan is
reconnected and detected, or until the next control unit
reboot.
Normal operation, Aux fan supervision generates a fault.
The auxiliary fan fault is temporarily replaced by a warning
indication.
The setting will revert automatically to Off.
Configuration of signal supervision functions 1...6.
Six values can be chosen to be monitored; a warning or fault
is generated whenever predefined limits are exceeded.

Signal supervision status word.
Indicates whether the values monitored by the signal
supervision functions are within or outside their respective
limits.
