F32161 — Encoder 2: Analog sensor channel B failed

F32161 reports that the input voltage of the analog sensor connected as Encoder 2 has left the range the drive can process, so channel B of the sensor no longer delivers a usable actual value. The manuals for the G130/G150 and the S120/S150 describe this fault identically. The drive records which limit was violated as a decimal fault value in r0949. Depending on how the drive is configured, the same condition can also be signaled as an alarm or with no automatic reaction.

• The voltage applied at the input of the analog sensor is outside the limits the drive permits for evaluating the encoder signal.

1. Read the fault value in r0949 as a decimal number; it tells you which of the three limit violations the drive detected.
2. Fault value 1: verify the voltage that the analog sensor delivers at its output.
3. Fault value 2: verify the voltage per encoder period set in p4675 against the connected sensor.
4. Fault value 3: check the range limit threshold set in p4676 and increase it if the setting is too tight.

• 1: Input voltage outside detectable measuring range.
• 2: Input voltage outside the selected measuring range (p4675).
• 3: The absolute value of the input voltage has exceeded the range limit (p4676).

• r0949 — displays the fault value of this message; read it as a decimal number to tell the three causes of F32161 apart.
• p4675 — holds the voltage per encoder period of analog sensor channel B; compare this setting with the connected sensor when the fault value is 2.
• p4676 — holds the range limit threshold of the analog sensor; check this threshold and raise it if necessary when the fault value is 3.

Remove the cause first. The fault is acknowledged with pulses inhibited (pulse inhibit acknowledgment); once it has been acknowledged and the cause remedied, the drive can be restarted. If the drive is configured to output this condition only as an alarm or with no reaction, the drive keeps running and no acknowledgment is required.
