Use of the current setpoint filters depending on the resonant frequency

[5-3] Use of the current setpoint filter depending on the resonant frequency

• Resonant frequencies ≥ f

limit_SPEED

= 70 Hz ... 110 Hz

This filter is suitable for use with resonant frequencies in the range around or above the limit

frequency of the speed controller.

• Resonant frequencies < f

limit_SPEED

Please follow the Lenze recommendation and select suitable speed profiles, S-ramp or S-rounding,

for avoiding resonances.

Setting of the current setpoint filter

Since the frequency response of the speed controlled system is only rarely known to such an extent

that the current setpoint filters can be adjusted to the controlled system in the run-up, the following

example describes an experimental procedure for setting the current setpoint filters:

 Stop!

If the filter parameters are set incorrectly, the impaired closed-loop control can respond

with too large overshoots and cause the controller to become unstable, e.g. if the filter

width is set to a value more than twice as large as the filter frequency.

After setting the filter parameters, the drive behaviour during stop and quick stop (QSP,

Fail-QSP) must be checked. If impairments exist,

• the still running drive must either be coasted down by activating the controller inhibit

or immediately be brought to a standstill via a brake.

• the speed controller must afterwards be optimised again.

• the test procedure must be repeated.

 Normal and intended use of the current setpoint filter

 Use of the current setpoint filter is only partially suitable

 The current setpoint filter should not be used
