184 Parameters
31.33 Emergency ramp
supervision delay If parameter 31.32 Emergency ramp supervision is set to 0%,
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
73B0
Emergency ramp failed , sets bit 8 of 06.17 Drive status word
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.
0 s
0…100 s Maximum ramp-down time, or supervision activation delay. 1 = 1 s
31.36 Aux fan fault
bybass 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 stuck or disconnected, the control program generates a
fault (
5081 Auxiliary fan broken ).
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 (
A582 Auxiliary
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.
Off
Off Normal operation, Aux fan supervision generates a fault. 0
Temporarily
bypassed The auxiliary fan fault is temporarily replaced by a warning
indication.
The setting will revert automatically to
Off .

32 Supervision
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 (page 92 ).
32.01 Supervision status Signal supervision status word.
Indicates whether the values monitored by the signal
supervision functions are within or outside their respective
limits.
Note: This word is independent of the drive actions defined
by parameters 32.06 , 32.16 , 32.26 , 32.36 , 32.46 and 32.56 .
