3.2.4 Control Connections

3.2.4.1 Control Supply

In the standard product, the control must be powered separately by means of a 24 Vdc external power supply
connected to connector X5. Doing so, all the power stage of the servo drive can be turned off without losing its
communication with other devices connected in network, for instance.
Specifications of the external supply of 24 Vdc, -15 %, +20 %, current:
1 A (models SCA06B05P0D2 and SCA06C08P0T2)
2.5 A (other models).

Note: The supply reference (-) is interconnected to the protective earth (PE) by means of a grounding screw.
If not desired or if problems of circulating currents occur because the 24 Vdc external supply is also grounded,
the connection to the PE can be opened by simply removing the grounding screw.
The location of the screw is shown below; in the SCA06C08P0T2, it is necessary to remove the fan to access the screw.
