8.3.1.1
Electrical equipment
The following equipment is provided by the spindle manufacturer:
● Terminal box box or connector, version with at least IP54 according to EN 60034
● Protective tubing for the free cable ends from the spindle
● Ground cable with cable lug
8.3.1.2
Connecting cables
In the standard version, the stator core has the following connection cables:
● Power connection marked U1, V1, W1
● 2 cables for the temperature sensor (of which 1x is a reserve), two-conductor, each
cable cross-section is 0.22 mm², with color coding, diameter 3 ... 4 mm.
Note
Electrical connection via terminal box or power connector
The power cables of the motor are not suitable as direct electrical interface of the
spindle.
The spindle must be electrically connected via a terminal box or power connector.
● Route out the free cable ends from the spindle box in a suitable protective tubing with
cable gland to a terminal box box provided by the customer.
● Ensure effective strain relief. Comply with the specified bending radii (minimum, 3 to
4x the outer cable diameter).
● To connect the motor to a converter, use MOTION-CONNECT cables or shielded
connecting cables from the terminal box or power connector interface.
Note
The maximum length of the connecting cable is 50 m with and without VPM.
● Due to the high voltages, use cables for higher mechanical requirements in
combination with a connection socket and VPM.
