Digital Brushless AC servo drive system - Ref.0707
MCS- 21/92
Power connectors and encoder output
It includes the connectors of the brake itself (pins 4 and 5). A voltage between 22 V
DC and 26 V DC releases the shaft. When installing the motor, verify that the brake
releases the shaft completely before turning it for the first time.
Connecting the motor windings in the order indicated on the connector (U, V, W), the
shaft will turn clockwise (CWR, clockwise rotation).
Pins 3 and 4 of the encoder connector correspond to the thermistor PTC KTY- 84 for
monitoring motor temperature.
