Product safety

• 100 % short-circuit proof

• 100 % earth fault protection

• Mains transient protection

• Switching on input

• Switching on output

• Galvanic isolation

• Designed according to EN 50178

Speed compensation precise stop

• Better process control

• Same stopping distance independent of initial motor speed

Precise stop

• Interrupt controlled stop

• Higher process repeatability

• Well defined stopping

Counter stop

• Accurate positioning

• High frequency input (65 kHz)

• 24 V incremental encoder input

• AB encoder input as option

Automatic motor tuning

• Perfect match between motor and drive

• Measures the stator resistance (RS) Better shaft performance

• Measurements done without applying torque

• Checks for missing motor phases
