Control Function Pole-Changing Starter

Use this function in a feeder that requires a two-pole or dahlander motor to start-stop in one direction of rotation.
• Speed 1: contactor on output DO0, DI4 for start; parameter Ie1 for motor current
• Speed 2: contactor on output DO1, DI3 for start, parameter Ie2 for motor current
• Optionally DI0 can be used for contactor checkback supervision
• Optionally DI4/DI3 can be used to start the motor at speed one/two and DI5 to stop it
• Optionally DO2 or DO3 can be used as fault output
The voltage dip function is not supported in this control function
Set I according to the motor nameplate

The following diagram shows the UMC wired for two-pole operation. A signal lamp is connected to DO3 which serves as a fault out-
put. The main contactor is connected to DO0 and DO1. Two auxiliary contacts are used for contactor checkback monitoring. The
motor can be started locally via DI4 (speed one) or DI3 (speed two) and stopped via DI5. The remaining digital inputs can be freely
used.
