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.
Configuration of signal supervision functions 1...3.
Three 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

Signal supervision status word.
Selects the mode of signal supervision function 1. Determines
how the monitored signal (see parameter 32.07) is compared
to its lower and upper limits
The action to be taken when the condition is fulfilled is
selected by 32.06.
Signal supervision 1 not in use.
Action is taken whenever the signal falls below its lower limit.
Action is taken whenever the signal rises above its upper
limit.
Action is taken whenever the absolute value of the signal falls
below its (absolute) lower limit.
Action is taken whenever the absolute value of the signal
rises above its (absolute) upper limit.
Action is taken whenever the signal falls below its low limit or
rises above its high limit.
Action is taken whenever the absolute value of the signal falls
below its (absolute) low limit or rises above its (absolute) high
limit.
