● Encoder connection
Notes on connecting up the motor
In the standard version, the stator core has the following connection cables:
● Power connection with identification
● 2 cables for the temperature sensor (of which 1 is a spare), 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.
t 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
