Description
If parameter 31.37 Ramp stop supervision
parameter defines the maximum time a ramp stop is allowed
to take. If the motor has not stopped when the time elapses,
the drive trips on 73B1 Stop
status word 2, and coasts to a stop.
If 31.37 is set to a value other than 0%, this parameter
defines a delay between the receipt of the 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.
Selects warnings to be suppressed. The parameter is a 16-
bit word with each bit corresponding to a warning. Whenever
a bit is set to 1, the corresponding warning is suppressed.
The bits of this binary number correspond to the following
warnings:
Warning suppression word.
Sets a custom motor current fault limit.
The drive automatically sets an internal motor current limit
according to the drive hardware. The internal limit is
appropriate to the drive hardware. The internal limit is
appropriate in most cases, but this parameter can be used to
set a lower current limit, for example, to protect a permanent
magnet motor from demagnetization.
With this parameter at 0.0 A, only the internal limit is in force.
Custom motor current fault limit.
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
supervision functions are within or outside their respective
limits.
Note: This word is independent of the drive actions defined
