F01640 — SI P1 (CU): component replacement identified and acknowledgment/save required

F01640 is raised by the “Safety Integrated” (SI) function in the Control Unit when it identifies that a component of the drive has been replaced. While the fault is present, the affected drive can no longer be operated. The fault value in r0949 shows bit by bit which component the drive considers replaced, and in addition the SI diagnostics bits r9776.2 and r9776.3 are set. Depending on how the drive is configured, the same condition can also be signalled as an alarm or without a reaction.

• The “Safety Integrated” function has identified that a component has been replaced — the fault value names the component concerned (see the bit list below).

1. When safety functions are active, carry out a partial acceptance test after the component replacement.
2. Acknowledge the component replacement: set p9702 = 29.
3. Save all parameters: set p0977 = 1 or p0971 = 1, or perform “copy RAM to ROM”.
4. Acknowledge the fault itself, for example via the binector input p2103.

The message value carries the fault cause; the drive stores it in r0949, to be interpreted binary. Each bit set to 1 identifies one replaced component:

• Bit 0 = 1: the Control Unit has been identified as replaced.
• Bit 1 = 1: the Motor Module/Hydraulic Module has been identified as replaced.
• Bit 2 = 1: the Power Module has been identified as replaced.
• Bit 3 = 1: Sensor Module channel 1 has been identified as replaced.
• Bit 4 = 1: Sensor Module channel 2 has been identified as replaced.
• Bit 5 = 1: sensor channel 1 has been identified as replaced.
• Bit 6 = 1: sensor channel 2 has been identified as replaced.

• r0949 — fault value: read here as a binary pattern to see which of the components the drive has identified as replaced.
• p9702 — SI acknowledge component replacement: enter the value 29 to acknowledge the identified replacement.
• p0977 — save all parameters: set to 1 to save all parameters after the replacement has been acknowledged.
• p0971 — save drive object parameters: set to 1 as the alternative stated for saving, or use “copy RAM to ROM” instead.
• p2103 — BI: 1st acknowledge faults: the binector input through which the fault can be acknowledged.
• r9776 — SI diagnostics: bits 2 and 3 are set here in addition to the fault.

Acknowledge in this order: first the component replacement with p9702 = 29, then save all parameters (p0977 = 1, p0971 = 1 or “copy RAM to ROM”), and finally the fault itself — for example via the binector input p2103. The affected drive can only be operated again once the fault has been cleared this way. When safety functions are active, the partial acceptance test after the component replacement is additionally required.
