F30665 — SI P2: System is defective

F30665 reports that the SI P2 system has found a defect — either before the previous boot or within the one in progress; the system may also have rebooted itself (reset). The fault value, which you read in r0949 and interpret as a hexadecimal number (the manual prints it as the placeholder %1 in the message value), tells you which situation applies and which setting, if any, is wrong. On a G120 Power Module with "STO via terminals at the Power Module" (STO_A/STO_B), value 40 hex says: the STO terminals are active because the DIP switch sits in the "ON" position, while the function is not yet enabled (p9601.7 = p9801.7 = 0). On a Power Module of the S120, S150, G130 and G150, value 2 hex says: p9500 and p9300 do not match — you recognise this because Safety message C30711 appears at the same time. Values 200000 hex and 400000 hex (on the G120 also 4000yy hex) describe a fault inside the current booting/operation; every other value means the defect was already present before the drive last booted.

• A system defect was found either before the previous boot or within the one in progress; the system may have rebooted itself (reset).
• On a G120 Power Module with "STO via terminals at the Power Module": the STO_A/STO_B terminals are active (DIP switch "ON"), but the function is not enabled (p9601.7 = p9801.7 = 0) — this is fault value 40 hex.
• On a Power Module of the S120, S150, G130 and G150: p9500 and p9300 are not identical, which shows up together with Safety message C30711 — this is fault value 2 hex.
• For 200000 hex or 400000 hex (G120 additionally 4000yy hex): a fault during the running booting/operation; further values indicate a defect that already existed before the previous boot.

1. Read the fault value in r0949 as a hexadecimal number and find your case below.
2. Perform a POWER ON: switch the converter off and back on. This step belongs to every fault value.
3. For 40 hex: either move both DIP switches on the Power Module to "OFF" — this deactivates the STO_A/STO_B terminals — or enable the "STO via terminals at the Power Module" function.
4. For 2 hex: compare p9500 with p9300; both must carry the same value (this applies when Safety message C30711 appears alongside).
5. For 400000 hex: make sure the Control Unit is physically connected to the Power Module.
6. For 4000yy hex on the G120: make sure the Control Unit is physically connected to the Power Module and deselect the "STO via terminals at the Power Module" function.
7. Should the fault return: update the firmware to a newer version and then get in touch with Technical Support.

• The message value is the fault value; it appears as the placeholder %1 and you read it in r0949, interpreted as a hexadecimal number.
• 40 hex — G120 Power Module with "STO via terminals at the Power Module" (STO_A/STO_B): the STO terminals are active because the DIP switch is in the "ON" position, while the function is not enabled (p9601.7 = p9801.7 = 0).
• 2 hex — Power Module of the S120, S150, G130 and G150: p9500 and p9300 do not match; Safety message C30711 then appears at the same time.
• 200000 hex and 400000 hex (G120: 200000 hex and 4000yy hex) — a fault inside the current booting/operation.
• Additional values — the defect was already present before the drive last booted.

• r0949 — displays the fault value of F30665; read it as a hexadecimal number to identify your case.
• p9601 — SI enable functions, processor 1: bit p9601.7 belongs to enabling the STO terminal function on the G120; with 40 hex it still reads 0.
• p9801 — SI enable functions, processor 2: bit p9801.7 goes together with p9601.7; for fault value 40 hex both bits read 0 while the terminals are already active.
• p9500 — SI Motion monitoring clock cycle of the Control Unit: with fault value 2 hex compare it against p9300.
• p9300 — SI Motion monitoring clock cycle of the Motor Module: it must have the same value as p9500 (relevant when C30711 is shown as well).

The drive coasts down (OFF2) and the fault must be acknowledged immediately before a restart is possible. Start with a POWER ON — switch the converter off and back on. If the cause for 40 hex, 2 hex, 400000 hex or 4000yy hex was removed beforehand, the drive should restart normally. If F30665 returns, update the firmware to a newer version and get in touch with Technical Support.
