10.2 Parameter list
Par. No. Name
p29131 Gain Switching Condition:
Pulse Deviation
Description: Triggers position deviation threshold for gain switching. If the gain switching function is enabled
and this condition is selected:
Switch from the first group of control parameters to the second group when the position deviation is larger
•
than the threshold.
Switch from the second group of control parameters to the first group when the position deviation is small-
•
er than the threshold.
p29132 Gain Switching Condition:
Position Setpoint Fre-
quency
Description: Triggers pulse input frequency (PTI) threshold or internal position speed (IPos) threshold for gain
switching. If the gain switching function is enabled and this condition is selected:
1. PTI
– Switch from the first group of control parameters to the second group when the pulse train input pulse
is higher than the threshold.
– Switch from the second group of control parameters to the first group when the pulse train input is low-
er than the threshold.
2. IPos
– Switch from the first group of control parameters to the second group when the speed of fixed position
setpoint is larger than the threshold.
– Switch from the second group of control parameters to the first group when the IPos is smaller than the
threshold.
p29133 Gain Switching Condition:
Actual Speed
Description: Triggers speed threshold for gain switching. If the gain switching function is enabled and this
condition is selected:
Switch from the first group of control parameters to the second group when the actual motor speed is
•
larger than the threshold.
Switch from the second group of control parameters to the first group when the actual motor speed is
•
smaller than the threshold.
p29139 Gain switching Time
Constant
Description: Time constant for gain switching. Set this parameter to avoid frequent gain switches that reduces
system reliability.
