External Motor Chokes

The ESCON 70/10 features built-in motor chokes that are suitable for most motors and applications.
Nevertheless, in case of high power supply vV

CC

in combination with high continuous output cur-

rent and a motor with very low inductance, the current ripple will become too high. This will cause
unnecessary motor heating and unstable control behavior. In this case, an additional, external 3-phase
motor choke will be necessary.

Use the following formula to determine whether an additional motor choke will be required:
