Motor Control Using a Standard or STO Motor Starter for Motors with Brake

Overview

CAUTION
OVERHEATING
When you connect and operate motors with built-in brakes, be aware of the hazard of overheating. The energy to release the brakes is taken from the motor connection cables, which can cause asymmetrical power consumption and result in overheating.
Failure to follow these instructions can result in injury or equipment damage.
CAUTION
UNINTENDED EQUIPMENT OPERATION
The current setting of the TeSys H motor starter must be the nominal current of the motor increased by the value of the brake nominal current.
Failure to follow these instructions can result in injury or equipment damage.
NOTICE
DAMAGE TO MOTOR
Connect the TeSys H motor starter as specified in the wiring diagrams.
Failure to follow these instructions can result in equipment damage.

This section provides circuits for motors with a brake. The wiring diagram you use depends on voltage supply of the brake, either 230 Vac or 400 Vac.

Activate external brakes by using a separate contactor, such as TeSys D.

Three-Phase Motor Control with a 230 Vac Brake

The current for braking is taken from one phase and the neutral conductor. Connect the brake to the phase that goes to T2 and neutral.

Three-Phase Motor Control with a 400 Vac Brake

The current for braking is taken from two phases. Connect the brake to the phases that goes to T1 and T3.
