ELSM^®

The ELSM^® control mode allows the operation of permanent-field synchronous servomotors without encoder.

This procedure is exclusively intended for applications in horizontal materials handling technology with one single motor. It is not permitted to use it in vertical drives, inclining tracks or as a group drive.

Make sure that the inverter provides at least 150% I₀ of the motor throughout the rotor alignment process.

Switching to a rotating motor is possible (flying start function). Continuous operation is only permitted above a transition speed of approx. 2% of the nominal motor speed.

• Rotor adjustment/rotor position measurement
• Speed control
• Torque control
