Description
Parameters 31.37 Ramp stop supervision
stop supervision delay, together with
rate, provide a supervision function for normal (ie. non-
emergency) 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,
maximum allowed deviation from the expected deceleration
rate, which is calculated from parameters 23.11...23.19. If the
actual deceleration rate (01.29) deviates too much from the
expected rate, the drive trips on
of 06.17 Drive status word
If 31.32 is set to 0% and
supervision is disabled.
Maximum deviation from expected deceleration rate.
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 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.
Note: The limit defines the maximum peak current of one
phase.
With this parameter at 0.0 A, only the internal limit is in force.
