Par. No. Name
p29140 PI to P: Mode Selection
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
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-
tion: Speed
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.
•
p29143 PI to P Switching Condi-
tion: Acceleration
Description: 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-
tion: Pulse Deviation
Description: 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.
•
p29240 Select Referencing Mode
Description: Selects referencing mode.
0: Referencing with external signal REF
•
1: Referencing with external reference cam (signal REF)
•
2: Referencing with zero mark only
•
3: Referencing with external reference cam (CCWL) and zero mark
•
4: Referencing with external reference cam (CWL) and zero mark
