System Power Wiring & Interlocks
System Power Wiring & Interlocks
The SMLC provides integrated emergency stop and fault interlocks through the servo drives .
System wiring diagrams for standard ORMEC servo drives, which include the recommended safety and
fault interlocks for a typical system, are provided in the Appendix B, page # 53. The primary features of
these system ‐ wiring diagrams are:
•
The Main Power Contactor switches servomotor power, called Main Power.
•
For the Main Power Contactor to be enabled, both the ServoWire Drive E ‐ Stop/Quick Stop input
and the Drive Ready output must be closed.
•
For the Drive Ready output on the servo drive to be closed, five conditions must be satisfied:
•
There must be no SMLC diagnostic faults, including power ‐ up diagnostics.
•
There must be power (+5 to +24 referenced to RTN) applied to the drives V+S input and RTN
must be connected to V ‐ S.
•
There must be current flow from the drives E ‐ Stop/Quick ‐ Stop input to V ‐ S.
•
There must be no drive faults from any standby or active servo drive and no open encoder signal
wires on axes in pacer, standby, or active mode.
•
Bus power must be applied to the drive.
There are many acceptable variations of these System Wiring Diagrams. If using a variation, it should
incorporate the primary features as described above and as shown in the Appendix. Contact the ORMEC
Service Department with any questions you may have in this area.
