Page 5: General Information
The motor voltages and the motor currents are sinusoidal. A maximum motor efficiency is achieved by means of a compensating current control. The DS 2420 drives can be used as single-axis position amplifier or torque or speed amplifier. The position and speed actual value is generated in the encoder unit (resolver or incremental encoder). -
