p29133 Gain switching condition:
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-
Time constant for gain switching. Set this parameter to avoid frequent gain switches that reduces
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.
Only when the auto tuning function (p29021=0) and gain switching function are both disabled can the
PI/P switching function be used.
PI to P switching condi-
tion: Torque
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.
p29142 PI to P switching condi-
0 210000 2000 rpm Float IM T
Description: Triggers speed 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 speed is larger than the threshold.
•
Switch from the P control to the PI control when the actual speed is smaller than the threshold.
PI to P switching condi-
tion: Acceleration
Triggers acceleration 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 acceleration is larger than the threshold.
•
Switch from the P control to the PI control when the actual acceleration is smaller than the threshold.
p29144 PI to P switching condi-
Triggers pulse deviation 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 pulse deviation is larger than the threshold.
•
Switch from the P control to the PI control when the actual pulse deviation is smaller than the threshold.
MDI direction selection:
• 0: Absolute positioning through the shortest distance
• 1: Absolute positioning through the positive direction
• 2: Absolute positioning through the negative direction
