NOTE
Severe filtering can be detrimental to dynamic
performance.
This parameter is used with H-40 Configuration Mode [1]
Speed closed loop and [2] Torque control.
The filter time in flux sensorless must be adjusted to
3-5 ms.
Illustration 3.46 Feedback Signal
PI-07 Speed PID Feedback Gear Ratio
Range: Function:
1 * [0.0001 - 32.0000]
Illustration 3.47
PI-08 Speed PID Feed Forward Factor
Range: Function:
0 % * [0 - 500 %] The reference signal bypasses the speed
controller by the amount specified. This
feature increases the dynamic performance
of the speed control loop.
3.21.2 PI-1# Torque PI Control
PI-12 Torque PI Proportional Gain
Range: Function:
100 % * [0 - 500 %] Enter the proportional gain value for the
torque controller. Selection of a high value
makes the controller react faster. Too high
a setting leads to controller instability.
PI-13 Torque PI Integration Time
Range: Function:
0.020 s * [0.002 - 2 s] Enter the integration time for the torque
controller. Selection of a low value makes
the controller react faster. Too low a
setting leads to control instability.
3.21.3 PI-2# Proces PID Feedback
Parameters to configure the feedback sources for the
Process PID Control.
PI-20 Process CL Feedback 1 Resource
Option: Function:
The effective feedback signal is made
up of the sum of up to two different
input signals.
Select which frequency converter
input should be treated as the source
