C30700 — SI Motion P2: STOP A initiated

C30700 is a safety message from the SI Motion P2 monitoring channel: the drive has been stopped with a STOP A. On the S120, S150, G130 and G150 the manual describes this as STO applied via the safety switch-off signal path of the Control Unit; on a G120 the pulses are suppressed via the safety switch-off signal path of processor 1. The STOP A can be a plain stop request, the response to a test stop whose STO did not become active within the parameterized time, or the follow-up reaction to another Safety Integrated message — for example a limit reached in the SAM (Safe Acceleration Monitor) or SBR (Safe Brake Ramp) monitoring.

• A stop request — from the Control Unit; on a G120, from processor 1.
• On the Control-Unit families, the STO was not active after the parameterized time in p9357 following test stop selection; the G120 manual words this as pulses not suppressed after test stop selection.
• A subsequent response to the message C30706 (SAM/SBR limit exceeded).
• A subsequent response to the message C30714 (Safely-Limited Speed exceeded).
• A subsequent response to the message C30701 (STOP B initiated).
• On the Control-Unit families only, a subsequent response to the message C01715 (Safely-Limited Position exceeded) or to the message C30716 (tolerance for safe motion direction exceeded).

1. Remove the cause of the fault on the Control Unit — on a G120, on the monitoring channel of processor 1.
2. Check the value in p9357 and increase it if required; this concerns the STO not becoming active in time after a test stop.
3. Check the switch-off signal path: on the Control-Unit families the switch-off signal path of the Control Unit, including the DRIVE-CLiQ communication; on a G120 the switch-off signal path of processor 2.
4. Carry out the diagnostics routine for whichever of the preceding messages occurred — C30706, C30714 or C30701 on every family, and on the Control-Unit families additionally C30715 and C30716.
5. If the cause cannot be found, replace hardware: on the Control-Unit families the Motor Module, Power Module or Hydraulic Module, or the Control Unit; on a G120 the Power Module or the Control Unit.

• p9357 — SI Motion STO test time: the parameterized time within which the STO must become active after a test stop is selected; for this message, check the value and increase it if required.

The message is cleared by acknowledging it, after which the drive can be restarted. On the Control-Unit families the manual lists four safe-acknowledgment routes that work without a POWER ON: Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe and the machine control panel. On a G120 the message can be acknowledged using Acknowledge internal event.
