The following must be taken into consideration:
- Adequate sizing of the contactors
- Terminal X1/9 on the amplifier should open parallel with the opening of the mains contactors. If the
time is exceeded there may be a fault message: “Fault in the motor phase”. If the terminal X1/9 is not
opened, this can lead to a defect in the drive. Opening terminal X1/9 also protects the contactor as the
drive is disabled before the contactors are opened (powerless switching of the contacts).
- A rapid start-up is possible (required when using a light curtain).
Please note the following disadvantages on this type of circuit:
- When the drive is enabled, you may be switching a DC current with the contactor. The motor winding is
an inductivity.
- The resulting induction voltage can damage the drive. For this reason you must always first switch off
the terminal X1/9 (Enable) at the ACOPOS drive before opening the contactor.
- Consider the correct design for the contactor. In the worst case scenario you switch 800 V

.
Note: Many customers also loop additional contacts into the motor line in order to achieve the safety category
4. Whether or not this is actually fulfilled (overall machine: electronics and indexer mechanism), this decision
must be made by the individual customer.
It has to be taken into consideration that, although the motor can be switched powerless in accordance with
safety category 4, this does not guarantee that the Axes are coming immediately to a standstill.
