"Axis0, Axis1 and Axis2" motor drive connectors
Each motor connection is a 7W2 connector for connection of a CMM motor to the UCC T3 , as shown below:
Connector pin | Function |
|---|---|
A1 | Positive motor connection (default) |
A2 | Negative motor connection (default) |
1 | Positive tacho input (default) |
2 | Negative tacho input (default) |
3 | Ground reference |
4 | Negative tacho input (linked to pin 2) |
5 | Ground reference |
Shell | Screen |
The table shows the default polarity configurations for all pins.
NOTE: The motor and tacho polarities on the UCC T3 controller are software-configured during the installation process. The maximum tacho voltage is 100 V. If one terminal of the tacho is grounded, the maximum voltage is reduced to 18 V. It is recommended that a differential tacho is used.
CAUTION: The UCC T3 motor connections must be blanked off if not being used to prevent accidental contact which could result in an electric shock.
