Function:
[ 0.0001 - The frequency converter multiplies
32.0000] the speed feedback by this ratio.
Motor
Par 7-07=1.00
Function:
[0 - 500 %] The reference signal bypasses the
speed controller by the amount
specified. This feature increases the
dynamic performance of the speed
control loop.
Function:
[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.
Function:
[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
controller instability.
