4.8 Electrical equipment
The main drive motor (single phase series-wound motor) is supplied already installed
■ The main spindle drive has an ON/OFF switch with under-voltage trigger.
■ In order for the machine to start, the turn switch for forwards-reverse must be set to the required
direction of rotation.
■ Then switch on at the ON/OFF switch.
■ The ON/OFF switch must also be switched on again after the power is interrupted.
■ To change the direction of rotation of the main drive motor, the turn switch must briefly rest at the 0
position to allow the relays on the control board enough time to switch.
■ In the event of the main drive motor being overloaded, it will switch itself off automatically. The
main drive motor can only be switched back on again after a short waiting period.
