Notes. The I/O selected in the figure have been chosen arbitrarily. In general any Ixx and Oxx may be used always
matching the ones used in the PLC.
It is very common to choose I1 and O1 for the external emergency. Therefore, we suggest not to use them for this
application. If they are going to be used, make sure that they have not been set to be used as emergency input and
output.
Important warnings
1. Either an external auxiliary power supply or a FAGOR power supply may be used to supply the 24 V DC.

2. To brake the motor in a controlled way during a power failure, make sure that 24 V DC will be supplied to
3. When using a compact SCD drive to govern a spindle motor, you must necessarily install an external auxiliary

WARNING. If you decide to install an external auxiliary power supply, make sure
that in case of a power outage, the 24 V DC are ensured to brake the motor
under control preventing it from braking by inertia. Ignoring this warning may
cause personal injury.
