Important warnings
1. Either an external auxiliary power supply or a FAGOR power supply may be used to supply the 24 V DC.
Never connect both at the same time !
2. To brake the motor in a controlled way during a power failure, make sure that 24 V DC will be supplied to
contactors - KM1 and - KM2 and relays - KA3 and - KA4. This situation is ensured if you have installed a
FAGOR power supply next to an SPD modular drive. If you have installed an external auxiliary 24 V DC power
supply, you must make sure that this condition is ensured.
3. When using a compact SCD drive to govern a spindle motor, you must necessarily install an external auxiliary
power supply to provide the 24 V DC. These compact drives do not have an output 24 V DC connector.
Note. See these currents in chapter 6. Selection , of the FM7/FM9 motor manual.
Sizing of motor power cables
Note. See the necessary cable section according to table of the chapter 4. Installation of the FM7/FM9 motor manual.
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.

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.
* WARNING. Never connect an external
auxiliary power supply and a FAGOR
power supply at the same time.
