Recommendations

Receipt

Ensure that the equipment reference marked on the label conforms to the delivery note corresponding to the purchase order.

Open the packaging and check that the equipment has not been damaged in transit.

For successful setup, it is important to check that the braking unit, protection devices and mounting are correct. For more information, please

contact your local representative.

Capacitor discharge!

Before any operation on or in the braking unit, disconnect the power line supply and wait 15 minutes for the DC bus to discharge completely.

Measure the voltage on the DC bus before any intervention. This should be less than 60 V DC.

Automatic restart!

In certain cases, depending on its parameter setting, the drive may restart automatically when the power is restored. The safety of nearby

equipment and people must be assured.

General

As a motor slows down on a deceleration ramp, it is working as a generator. A drive uses a rectifier and cannot return electrical energy to

the distribution network.

During operation as a generator, the voltage at the DC bus terminals increases due to the restoration of energy from the motor to the drive.

This locks out the drive on a DC bus overvoltage fault.

The restored power in the drive depends on the inertia of the load to be braked and the required braking time.

The drive protects itself against locking out due to DC bus overvoltage by auto-adapting its deceleration ramp. If a shorter deceleration time

is required, a BRAKING UNIT must be used.
