Connecting the 4-axis Servo Module
4C-14
Touch Probe Connector - TB1
The servo module receives touch probe feedback through the connector
labeled TB1. Figure 4C.11 shows the location of this connector and lists
its terminal assignments.

1 The True level (voltage transition the probe fires) is either “HIGH”or “LOW”as
defined by the AMP parameter PROBE TRANSITION. Refer to your AMP
reference manual for more information.
Important: The touch probe connector supports only +5V probing device
applications.
5V DC Encoder Power Connector - P3
The servo module receives +5V dc power directly from the main power
supply through connector P3. This +5V dc power is used only for
powering the encoder. If the EXT Power connection on the encoder
termination panel is used or if the 15V DC encoder power is used the
connection to P3 is not needed. Figure 4C.12 shows an end view of
connector P3 and lists the pin assignments. For details on this connection
refer to the section on the main power supply connections on page 4D-4.
