Parameters 321
46.21 At speed hysteresis Defines the “at setpoint” limits for speed control of the drive.
When the difference between speed reference (
22.87 Speed
reference act 7
)
and the speed feedback ( 24.02 Used speed
feedback ) is smaller than 46.21 At speed hysteresis , the drive
is considered to be “at setpoint”. This is indicated by bit 8 of
06.11 Main status word .
50.00 rpm
0.00…30000.00
rpm Limit for “at setpoint” indication in speed control. See par.
46.01
46.22 At frequency
hysteresis Defines the “at setpoint” limits for frequency control of the
drive. When the absolute difference between reference
(
28.96 Frequency ref ramp input ) and actual frequency ( 01.06
Output frequency ) is smaller than 46.22 At frequency
hysteresis , the drive is considered to be “at setpoint”. This is
indicated by bit 8 of 06.11 Main status word .
2.00 Hz
0.00…1000.00 Hz Limit for “at setpoint” indication in frequency control. See par.
46.02
46.31 Above speed limit Defines the trigger level for “above limit” indication in speed
control. When actual speed exceeds the limit, bit 10 of
06.17
Drive status word 2 is set.
1500.00 rpm
0.00…30000.00
rpm “Above limit” indication trigger level for speed control. See par.
46.01
46.32 Above frequency
limit Defines the trigger level for “above limit” indication in
frequency control. When actual frequency exceeds the limit,
bit 10 of
06.17 Drive status word 2 is set.
50.00 Hz
0.00…1000.00 Hz “Above limit” indication trigger level for frequency control. See par.
