- / real32Parameters 31.37 Ramp stop supervision and 31.38
Ramp stop supervision delay, together with 1.29 Speed
change rate, provide a supervision function for normal
(ie. nonemergency) ramp stopping.
The supervision is based on either
• observing the time within which the motor stops,
or
• comparing the actual and expected deceleration
rates.
If this parameter is set to 0%, the maximum stop time
is directly set in parameter 31.38. Otherwise, 31.37
defines the maximum allowed deviation from the
expected deceleration rate, which is calculated from
parameters 23.11…23.19. If the actual deceleration rate
(1.29) deviates too much from the expected rate, the
drive trips on 73B1 Stop failed, sets bit 14 of 6.17 Drive
status word 2, and coasts to a stop.
If 31.37 is set to 0% and 31.38 is set to 0 s, the ramp
stop supervision is disabled.

0 s / real32If parameter 31.37 Ramp stop supervision is set to 0%,
this 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 failed,
sets bit 14 of 6.17 Drive 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.

- / uint16Selects 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:
