3.5.2.2 - 3-phase AC power supply in accordance with safety standard EN954-1 - category 1 with use of safety input
(1) if external potentiometer : resistance = 10 k
W
Note:
For single-phase standards, the power supply is connected to terminals l and n.
Qs: Fused isolator: Qs must be opened before any intervention on the electrical parts of the drive or motor.
aU: emergency stop button.
optional braking resistor. Dissipates the active power returned by the motor onto the drive Dc bus in the event of a driving machine.
Using the safety input means the motor can be stopped in freewheel mode without using a line contactor. the drive’s internal
principles are sufficiently safe to perform a stop using the safety input directly (category 1 of en954-1).
