p29132 Gain switching condition:
Position setpoint frequen-
cy
0 214700006
4
100 100
0
LU/
min
Float IM T
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
0 214700006
4
100 rpm Float IM T
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 con-
stant
8 1000 20 ms Float IM T
Description:
Time constant for gain switching. Set this parameter to avoid frequent gain switches that reduces
system reliability.

U16
IM
T
Description:
Selects a condition for the switch from PI control to P control under the speed loop.
• 0: Disabled
• 1: Torque is higher than a parameterizable setting value.
• 2: Using the digital input signal (G-CHANGE).
• 3: Speed is higher than a parameterizable setting value.
• 4: Acceleration is higher than a parameterizable setting value.
• 5: Pulse deviation is higher than a parameterizable setting value.
Note:
Only when the auto tuning function (p29021=0) and gain switching function are both disabled can the
PI/P switching function be used.
p29141 PI to P switching condi-
tion: Torque
0 300 200 % Float IM T
Description:
Triggers torque threshold for PI/P switching. If the PI/P switching function is enabled and this
condition is selected:
• Switch from the PI control to the P control when the actual torque is larger than the threshold.
• Switch from the P control to the PI control when the actual torque is smaller than the threshold.
