controller
The voltage controller is superimposed onto the selected characteristic curve. When
the voltage controller is used, a part of the available voltage is used as a control
reserve. The more dynamic the operation, the more control reserve is required. In
this case it may be that the voltage for rated operation is not sufficient, and also that
the controller starts to oscillate.
The PI voltage controller can be optimized by adaptation of the gain P345[0] -
CON_FM_VConKp, integral-action time P346[0] - CON_FM_VConTn and filter time
constant for motor voltage feedback P344[0] - CON_FM_VConTF. P347[0] - CON_
FM_VRef sets the voltage reference, though the threshold needs to be reduced in
response to rising demands as this maintains a kind of voltage reserve for dynamic
control processes.
A certain voltage reserve is required for stable operation. This is specified using P
347[0] - CON_FM_VRef (< 100%). The value should be set high (≤ 90%) where
there are high demands in terms of dynamic performance. When using a lower
dynamic performance instead, the maximum achievable torque can be optimized in
relation to the current by using higher values (> 90%).
