366 Parameters
46.21 At speed hysteresis Defines the “at setpoint” limits for speed control of the drive.
When the absolute difference between reference (22.87
Speed reference act 7) and actual speed (90.01 Motor speed
for control) 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.
100.00 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.
10.00 Hz
0.00 … 1000.00 Hz Limit for “at setpoint” indication in frequency control. See par.
