Parameter setting

• The flying restart algorithm injects a current into the motor to identify the current speed. This

flying restart current can be parameterised in C00991

in [%] relating to the rated motor current.

• The higher the current the higher the torque imposed upon the motor.

• If the current is too low, a wrong speed can be detected.

• The starting frequency of the flying restart algorithm can be set in C00992

.

• If it can be anticipated at which frequency the motor "caught" most frequently in a flying

restart process, this frequency is to be set here.

• The integration time of the phase controller is set in C00993

.

• The Lenze setting "60 ms" is adapted for machines with a medium power (45 kW).

• A guide value for the integration time can be calculated with the following equation as a

function of the motor power (C00081

):

• For accelerating the flying restart process, this guide value can be reduced.

• If the flying restart frequency (Frequency.dnActualRotatingFieldFrequency) oscillates too

much, the integration time has to be increased again.

• A longer integration time increases the time for "catching" the drive.

• To avoid starting a flying restart process at short-time controller inhibit, a time can be set in

C00995

for the minimum active controller inhibit time.

• Since a pulse inhibit > 500 ms causes a controller inhibit, this also applies to the pulse inhibit.
