EMC Motor Output Filter
This can help the drive achieve EMC and filter thermal conformance. It also ensures longer motor life by reducing the high
voltage slew rate and overvoltage stresses. Mount the filter as close to the VSD as possible. Please refer to Parker SSD Drives
for the selection of a suitable filter.
Motor Choke
Maximum Motor dv/dt = 10,000V/
μ
s. This can be reduced (when cabling is over 50m in length - to a maximum of 300m) by
adding a motor choke in series with the motor.
Installations with long cable runs may suffer from nuisance overcurrent trips. A choke may be fitted in the drive output to
limit capacitive current. Screened cable has a higher capacitance and may cause problems in shorter runs. Contact Parker SSD
Drives for recommended choke values.
