Optional for DR/DT/DV series AC motors and AC brake motors. The IS plug connector is delivered instead of the standard terminal box. The upper section of the IS plug connector (mating connector) is included in the scope of delivery. The IS plug connector is particularly compact and offers the following connection options:

Optional for DR/DT/DV series AC motors and AC brake motors. The mounted AB.. and AM.. plug connector systems are based on the Han Modular^® plug connector system made by Harting.

AB.. and AM.. plug connectors can be used for connecting single-speed motors. With brake motors, the brake control system can be either located in the terminal box or in the control cabinet. All versions of the brake control system are possible.

Optional for DR/DT/DV series AC motors and AC brake motors. The installed AC.. and AS.. connector systems are based on the Han 10E/10ES connector system made by Harting.

You can connect single speed motors.

Optional for DT/DV series AC motors and AC brake motors SEW-EURODRIVE proximity sensors are a simple and inexpensive means of monitoring whether the motor is turning. If a two-track proximity sensor is used, the direction of rotation of the motor can also be detected. Proximity sensors are mounted on the side of the fan guard and so do not increase the length of the motor.

Optional for DR/DT/DV series AC motors and AC brake motors. SEW-EURODRIVE incremental encoders output 1024 signals/revolution. They have two signal tracks and one index signal track.

Incremental encoders are available as hollow shaft encoders, spreadshaft encoders and solid shaft encoders with coupling. Signal output: TTL or sin/cos.

Optional for DT/DV series AC motors and AC brake motors The motors can be equipped with various encoder attachment fittings for mounting devices from different manufacturers.

Mounting devices for encoders are intended for spreadshaft encoders with an 8 mm (0.3 in) or 10 mm (0.39 in) center bore and for solid shaft encoders (synchronous flange).

SEW-EURODRIVE AV1Y and AV1H absolute encoders are combination encoders. They contain a multi-turn absolute encoder and a high-resolution sinusoidal encoder. You can choose between an SSI interface or a HIPERFACE^® interface for data transmission of absolute values. The AV1H absolute encoder has an electronic nameplate.

DT/DV series AC motors and AC brake motors can be equipped with a forced cooling fan on request. A forced cooling fan is usually not required for mains operated motors in continuous duty. SEW-EURODRIVE recommends a forced cooling fan for the following applications:

DR/DT/DV series AC motors and AC brake motors can be equipped with additional flywheel mass Z (flywheel fan) to facilitate smoother starting and braking response from mains-operated motors. The fan gives the motor an additional mass moment of inertia JZ. The flywheel fan replaces the normal fan and does not affect the external dimensions of the motor.

DT/DV series AC motors and AC brake motors can be equipped with a backstop if required. The backstop is used for protecting equipment against reverse movement when the motor is switched off.

Optional for DR/DT/DV series AC motors and AC brake motors. Liquids and/or solid foreign objects can penetrate the air inlet openings of motors when motors are mounted vertically with their input shaft pointing downwards.

Optional for DT/DV series AC motors and AC brake motors Motor noise is amplified by the drive fan guards. The low noise fan guard reduces the noise level by approximately 3 dB(A) when compared with the standard version.

For DR/DT/DV series multi-speed AC motors and AC brake motors. Normal multi-speed motors cannot switch from high to low speed without jerks unless special measures are taken.

The WPU smooth pole-change unit completes this task electronically and requires minimal wiring work.
