3-20 Wiring System, Axis, and Shunt Modules, and Motors (for all systems)
Connecting Thermal and Brake Leads to Axis Modules
Axis modules provide terminating points for the motor power,
thermal sensor, and brake. Axis module wiring is identical for all
available axis module ratings.
Figure 3.13
Locating TB1 and TB2
Important: Noise filters on the motor thermal sensor and brake
connectors (TB1 and TB2) add capacitance (1.0
µF)
from each leg of the thermal switch and motor
brake leads to ground. This should be considered
when selecting
ground fault circuits.
Connect the motor thermal sensor and brake lead to the Axis Module
at TB1 and TB2. Each axis module comes with a brake and thermal
connector kit. Refer to Appendix D for more information.
Required Tools and Equipment
• A small, flathead screwdriver
• One 1326-CPx1-xxx motor power cable for each axis
• One axis module connector kit (catalog number 1394-199) for
thermal switch and brake inputs. You will need one kit per axis
module as each kit contains two connectors.
