Special aspects in switching operation
When the motors are used in switching operation, it is necessary to exclude possible
interference of the switchgear using suitable wiring. According to EN 60204 (electrical
equipment of machines), motor windings must have interference suppression to pro-
tect the numerical or Programmable Logic Controllers. As it is primarily switching oper-
ations that cause interference, SEW-EURODRIVE recommends installing protective
circuit in the switching devices.
