An “Emergency switching off” requires an electrical isolation, e.g. by a central mains contactor.

Connection of active and passive sensors
The connection diagrams shown are only example circuits. The user is responsible for the correct safety-related design and selection of the components!

Safety-related characteristic values and further example circuits can be found in the project planning document.

Commissioning

Initial switch-on

DANGER!
Unexpected states during commissioning
Incorrect wiring can cause unexpected states during the commissioning phase. Possible consequences: Death, severe injuries, or damage to property

• Wiring must be complete and correct.
• Wiring must be free of short circuits and earth faults.
• The motor circuit configuration (star/delta) must be adapted to the inverter.
• The motor must be connected in-phase (rotating direction).
• Check the “emergency switching off” function of the overall system.
• Clear hazardous area.
• Observe safety instructions and safety clearances.

Preconditions:

• The power connections must be wired.
• Connector X3.1 (digital input 1) must be wired.

The control connections of the safety technology must be wired.

1. Switch on mains voltage.
2. Check readiness for operation.
3. Observe the “DRIVE” LED status display on the front of the inverter.

Carry out functional test
Objective: The motor connected to the inverter should rotate within the shortest possible time.

Preconditions:

• The connected motor matches the inverter in terms of power.
• The parameter settings correspond to the state upon delivery.
• The inverter is ready for operation. The mains voltage is switched on.

Start the drive and stop it again:

1. Drive enabled: X1/SIA = HIGH and X1/SIB = HIGH

2. Start drive: X3.1/DI1 = HIGH (switch closed)
   The drive rotates with 20 Hz.

3. Stop drive again: X3.1/DI1 = LOW (switch open)

Important notes

DANGER!
Unexpected and dangerous motor movements and system movements
Incorrect settings during commissioning may cause unexpected and dangerous motor and system movements.

Possible consequences: Death, severe injuries, or damage to property

• Clear hazardous area.

• Observe safety instructions and safety clearances.

Diagnostic interface X16 (USB interface)
The inverter has a built-in USB port (USB-C).

• The USB port may only be used temporarily for the diagnostics and parameterization of the inverter. We recommend keeping the inverter and diagnostics device on the same ground potential or disconnecting the diagnostics device from the mains.
• Parameterizing without motor operation does not require a mains voltage. If you connect the inverter directly to the PC without a hub, the USB interface of the PC is sufficient for the voltage supply.
