Connecting Your 1394 SERCOS Interface System 3-23
Wiring the TB1/TB2 Connectors (1326AB/AS Motors)
This procedure assumes you are using 1326AB/AS (resolver) motors, 
have the motor cable attached to the shield clamp, have wired the 
axis module terminal block, and are ready to connect the thermal 
switch and brake wires to the TB1 and TB2 connectors. Refer to 
Figure 2.8 to locate the TB1/TB2 connectors.
The 1326AB/AS (resolver) motor thermal switch and brake wires are 
in the motor power cable and must pass through noise filters (TB1 
and TB2) on the bottom of each axis module.
To wire your thermal switch and brake connections:
1. Prepare your conductors by removing the precut insulation or 
stripping approximately 10 mm (0.375 in.) of insulation from the 
end of each wire. 
2. Using the operating tool, insert the thermal switch and brake wires 
into the first connector (TB1) as follows and tighten the TB1 
screws.
IMPORTANT
One axis module connector kit (included with each 
axis module) is for thermal switch and brake inputs. 
You will need one kit per axis module as each kit 
contains two identical connectors. Refer to Appendix 
C for the connector kit replacement part number.
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.
IMPORTANT
Use caution not to nick, cut, or otherwise 
damage strands as you remove the insulation.
