Wiring the SLC Servo Module
5-7
Wiring the Estop for a One-Axis System
To wire the Estop for a one-axis system connect the following:
Drive enable
Estop reset pushbuttons (Res P.B., Res P.B., and Reset)
Customer Estop String (String In and String Out)
An Estop string (Figure 5.5) is connected in series and consists
of:
Axis hardware overtravels
Remote Estop
Motor thermal switch
Transformer thermal switch
Drive fault
Wiring for Normal Operation
Wire the Estop inputs for normal operation.
Bench test your SLC Servo Modules.
The Estop Reset pushbutton requires a two-pole single-throw
switch.
Maintaining Electrical Continuity
Maintain electrical continuity on the termination panel between
the String Out and String In terminals to change from an Estop
state to a run state when pressing the Estop Reset pushbutton.
While in the run state, loss of continuity between String Out and
String In places the SLC Servo Module in an Estop state.
All motion is inhibited in the Estop state.
Verifying Connections and Operation
Verify that the Estop wiring is connected correctly.
Check the operation of devices wired between String Out and
String In.
ATTENTION
!
To avoid personal injury or hardware damage,
develop a fail-safe wiring design for your Estop
string.
