AC30 series Variable Speed Inverter
AC Motor Chokes
The maximum rate of rise of Volts (dv/dt) present on the motor terminals of the inverter, can be as high as 10,000V/
µ
s. This can be
reduced by adding a motor choke in series with the motor.
Installations with long cable runs may suffer from nuisance overcurrent trips, refer to Appendix C Compliance - Cabling Requirements for
maximum cable lengths. An output choke may be fitted in the inverter output to limit parasitic capacitive current to earth. Screened cable
has a higher parasitic capacitance to earth and may cause problems in shorter runs. Contact Parker for recommended choke values.
