EMC-compliant installation
NOTICE!
Signal interference may be caused if the connection cables are too long.
Do not exceed a cable length of 3 m.
Observe the EMC protective measures described here.
EMC filter
Each electronics and motor supply cable must be installed directly at the unit with two
windings through a suitable ferrite sleeve (e.g. Würth Elektronik No.: 74270090).

EMC suppressor circuit with ceramic capacitors
If a ceramic capacitor (C1) is used in the PWM
nsoll
operating mode: To avoid faults, use a
signal source with a low internal resistance.
To update the firmware using the Motion Manager software, remove capacitor C2.
