4. Specifications regarding the machine
4.9 Electrical equipment 1.4 kW motor
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.
4.10 Electrical equipment 2.0 kW motor
The frequency-regulated main drive motor is delivered already installed
■ The machine has a switch with three settings (1=right or clockwise rotation - 0=zero position -
2=left or anti-clockwise rotation)
■ The under-voltage trigger is integrated in the electronics of the motor
■ In order for the machine to start or restart after a power interruption, the 3 setting switch must first
be switched to 0=zero position.
■ In 0=zero position, the switch must rest for about 5 seconds so that the motor is able to reset.
■ To change the direction of rotation of the main drive motor, the 3 setting switch must rest at the 0
position for approximately 1 second 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
