Parameter 32-62 Integral Factor
Table 1145: Parameter 32-62 Integral Factor
Parameter type: Range, 0 - 100000
Change during operation: True
The integral factor is the weighting factor with which, at time n, the sum of all motor position errors are evaluated.
Parameter 32-63 Limit Value for Integral Sum
Table 1146: Parameter 32-63 Limit Value for Integral Sum
32-63 Limit Value for Integral Sum
Parameter type: Range, 0 - 1000
Change during operation: True
This parameter limits the integral sum to avoid instability and PID wind-up if a feedback error occurs.
Parameter 32-64 PID Bandwidth
Table 1147: Parameter 32-64 PID Bandwidth
Parameter type: Range, 0 - 1000
Change during operation: True
The value 1000 means that the PID filter can output the full command value. For a Bandwidth of 500 only 50 % of the set value is
output.
Parameter 32-65 Velocity Feed-Forward
Table 1148: Parameter 32-65 Velocity Feed-Forward
32-65 Velocity Feed-Forward
Parameter type: Range, 0 - 100000
Change during operation: True
Velocity Feed-forward is a scaling factor that is multiplied with the derivative of the setpoint position (the velocity of the setpoint).
Use this function to get a more dynamic controller.
Parameter 32-66 Acceleration Feed-Forward
Table 1149: Parameter 32-66 Acceleration Feed-Forward
32-66 Acceleration Feed-Forward
Parameter type: Range, 0 - 100000
Change during operation: True
Acceleration Feed-forward is multiplied with the 2
nd
derivative of the setpoint position (the acceleration of the setpoint), and the
result is added to the control signal. Use this function to give an extra boost during acceleration.
