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
µ
F)
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.
