Section 4C
Connecting the 4-axis Servo Module
4C-20
The encoder termination panels are options with the analog system that
provide an easy and convenient means for you to connect and troubleshoot
your servo system. We strongly recommend the use of termination panels
when installing an analog system.
Termination panels feature:
D-shell connectors for cables from the servo module
(A-B cable number 8520-TPC)
Plug-type connectors for wiring to user devices
DIN Rail Mounting
All user connections with the exception of the analog out and touch probe
connections are routed through the termination panels. User side voltages
of +5V dc and +15V dc for encoder power (chosen by wiring to the
appropriate connector pin) are available on-board. External power
supplies for the encoders may also be routed through the termination panel
(refer to the feedback section).
Figure 4C.15 shows an encoder termination panel.
