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.
