F32160 — Encoder 2: Analog sensor channel A failed

F32160 reports that the input voltage of the analog sensor connected as Encoder 2 has left the permissible limits, so the drive no longer receives a usable channel A signal from this encoder. The exact reason is stored as a decimal fault value in r0949 (1, 2 or 3 — see the list below). The manuals describe the message identically for the different drive objects, so the explanation is the same regardless of which of them is affected. Depending on the configuration, the drive can also signal the same condition with no reaction at all or as an alarm instead of a fault. The analogous message for channel B is F32161 and is described on its own page.

• The input voltage of the analog sensor is outside the permissible limits; which limit was violated is recorded in r0949 as a decimal fault value.

1. Read the fault value in r0949 and interpret it as a decimal number to determine which of the three cases applies.
2. Fault value 1: check the output voltage of the analog sensor.
3. Fault value 2: check the voltage setting for each encoder period (p4673).
4. Fault value 3: check the range limit setting and increase it if necessary (p4676).

The drive places the fault value in r0949; interpret it as a decimal number:

• 1 — Input voltage outside detectable measuring range.
• 2 — Input voltage outside the measuring range set in p4673.
• 3 — The absolute value of the input voltage has exceeded the range limit (p4676).

• r0949 — fault value; read it here (decimal) to see which of the three voltage violations raised F32160.
• p4673 — voltage of analog sensor channel A per encoder period; check this setting when the fault value is 2.
• p4676 — range limit threshold of the analog sensor; check it, and increase it if necessary, when the fault value is 3.

The fault triggers an OFF1 response, at whose end the pulses are inhibited, and the acknowledgment is only accepted while the pulses are inhibited; once the cause has been remedied, acknowledge the fault and restart the drive. In the no-reaction variant of this message the drive neither reacts nor requires an acknowledgment.
