SRVO-007: External emergency stops
An E-stop wired into the external emergency stop inputs is active - a cell E-stop pushbutton, a line-level stop, or whatever the integrator landed on those terminals.
What it means
An E-stop wired into the external emergency stop inputs is active - a cell E-stop pushbutton, a line-level stop, or whatever the integrator landed on those terminals. The controller only knows the circuit is open; finding which device opened it is the actual work.
Common causes
Ranked by what technicians most often find, most likely first.
- Any external E-stop device pressed or latched somewhere in the cell or line.
- Open wiring in the external E-stop chain.
- Blown fuse (with SRVO-213 alongside).
- E-stop board fault.
How to fix it
- Walk the cell and check every external E-stop device - pushbuttons, rope pulls, line stops - release the latched one and press RESET.
- If nothing is pressed, the circuit itself is open: check terminals and continuity on the external E-stop inputs.
- If SRVO-213 appears with it, check fuses first.
- Never defeat or bypass the external E-stop chain to keep running.
