F32163 — Encoder 2: Analog sensor position value exceeds limit value

F32163 reports that the position value of Encoder 2 — evaluated as an analog sensor — has left the permissible range of -0.5 ... +0.5. The fault value stored in r0949 tells you which source delivered the out-of-range value: the LVDT sensor itself or the position value calculated through the encoder characteristic. Depending on how the drive is configured, the same condition can also be signalled as an alarm or with no reaction at all.

• The position value has exceeded the permissible range of -0.5 ... +0.5.
• With fault value 1, the out-of-range position value came from the LVDT sensor.
• With fault value 2, the out-of-range position value came from the encoder characteristic.

1. Read the fault value in r0949 as a decimal number to establish whether the LVDT sensor (fault value 1) or the encoder characteristic (fault value 2) delivered the out-of-range position value.
2. For fault value 1: check the LVDT ratio in p4678.
3. For fault value 1: check the reference signal connection at track B.
4. For fault value 2: check the coefficients of the characteristic in p4663 ... p4666.

• The drive stores the fault value in r0949; interpret it as a decimal number.
• 1: Position value from the LVDT sensor.
• 2: Position value from the encoder characteristic.

• r0949 — read the fault value here (interpret it as a decimal number); it tells you whether the out-of-range position value came from the LVDT sensor (1) or from the encoder characteristic (2).
• p4678 — the analog sensor LVDT ratio; check this setting when the fault value is 1.
• p4663 ... p4666 — the coefficients of the encoder characteristic (K0 ... K3); check these settings when the fault value is 2.

Remove the cause first (see the checks above). The fault is then acknowledged with pulse inhibit: the drive only accepts the acknowledgment once it has inhibited its pulses, i.e. after the drive object has been stopped, and only then can it be restarted. When the drive is configured to signal this condition as an alarm or with no reaction, no reaction and no acknowledgment apply.
