F30600 — SI P2: STOP A initiated

F30600 is reported by the drive-integrated "Safety Integrated" (SI) function when its second monitoring channel has detected a fault and initiated a STOP A. The manual defines this STOP A as STO via the safety switch-off signal path of monitoring channel 2. Two situations lead to it: the forced checking procedure (test stop) of this safety switch-off signal path was unsuccessful, or the fault is the subsequent response to F30611 (defect in a monitoring channel). The drive responds with OFF2, so it coasts to a standstill and will not restart until the fault has been acknowledged. On the G120 the manual describes the same event on processor 2 in terms of suppressed or enabled pulses rather than an active or inactive STO, and on HLA drive objects it is described for the Hydraulic Module. Which condition the drive saw is stored as a decimal fault value in r0949, and that value decides the remedy.

• The forced checking procedure (test stop) of the safety switch-off signal path of monitoring channel 2 was unsuccessful.
• The fault is the subsequent response to fault F30611 (defect in a monitoring channel).
• The concrete condition behind the STOP A is recorded as a decimal fault value in r0949 — see the decoding below.

1. Read the fault value in r0949 and interpret it as a decimal number; the decoding below shows which condition the drive detected.
2. Select Safe Torque Off (STO) and deselect it again.
3. Carry out a POWER ON (switch-off/switch-on) for all components.
4. For fault value 1005 on a Power Module with "STO via terminals at the Power Module" (terminals STO_A/STO_B): set both DIP switches to "OFF", or enable the "STO via terminals at the Power Module" function (it is disabled while p9601.7 = p9801.7 = 0).
5. For fault value 1020: upgrade the Motor Module/Hydraulic Module software and, if required, replace the Motor Module/Hydraulic Module.
6. For fault value 1030: check the discrepancy time and, if required, increase the value (p9650/p9850); then check the STO terminal at the Power Module (contact problems).
7. For fault value 9999: carry out diagnostics for fault F30611.
8. If the POWER ON does not clear the fault, replace the module involved — the Motor Module, the Power Module or the Motor Module/Hydraulic Module, depending on the converter.

The drive stores the fault value in r0949; interpret it as a decimal number.

• 0 — stop request from the Control Unit; on a G120, from processor 1.
• 1005 — STO active although STO is not selected and no internal STOP A is present; on the G120, pulses suppressed although STO is not selected and no internal STOP A is present. On a Power Module with "STO via terminals at the Power Module" (STO_A/STO_B), the terminals are active (DIP switch to "ON") although the function is not enabled (p9601.7 = p9801.7 = 0).
• 1010 — STO inactive although STO is selected or an internal STOP A is present; on the G120, pulses enabled although STO is selected or an internal STOP A is present.
• 1011 — internal error for STO deselected in monitoring channel 2; on the G120, an internal fault for the pulse enable in the Power Module.
• 1020 (Motor Module/Hydraulic Module) — internal software error in the "Internal voltage protection" function. The function is withdrawn and A STOP A that cannot be acknowledged is initiated.
• 1030 (Power Module, G120) — the feedback signals of the safety switch-off signal paths for the "STO via terminals at the Power Module" function are different.
• 9999 — subsequent response to fault F30611.

• r0949 — fault value: read it here and interpret it as a decimal number to identify the condition that initiated the STOP A and pick the matching remedy.
• p9601 — SI enable functions integrated in the drive (Control Unit): its bit 7 enables the "STO via terminals at the Power Module" function whose absence is reported with fault value 1005.
• p9801 — SI enable functions integrated in the drive (Motor Module): the counterpart of p9601; with fault value 1005 both p9601.7 and p9801.7 are 0, i.e. the function is not enabled.
• p9650 — SI F-DI changeover discrepancy time (processor 1): for fault value 1030, check this discrepancy time and increase it if required.
• p9850 — SI F-DI changeover discrepancy time (processor 2): checked and increased together with p9650 for fault value 1030.

The fault is acknowledged with a POWER ON, i.e. switching off and switching on again for all components; the manual's remedy additionally calls for selecting Safe Torque Off once and deselecting it again. If the fault comes back, work through the remedy for the specific fault value in r0949, and replace the Motor Module, Power Module or Hydraulic Module involved where the POWER ON does not help. Fault value 1020 is an exception: the STOP A initiated there cannot be acknowledged at all, so the Motor Module/Hydraulic Module software must be upgraded and the module replaced. After fault value 9999 the underlying fault F30611 must be diagnosed first.
