(*) WARNING. Never connect an external
auxiliary power supply and a Fagor power
supply at the same time.
Important warnings.
1. Either an external auxiliary power supply or a FAGOR power supply may be used to supply the 24 V DC. Never con-
nect 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.
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.
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 appli-
cation. If they are going to be used, make sure that they have not been set to be used as emergency input and output.
