F33160 — Encoder 3: Analog sensor channel A failed

Channel A of the analog sensor connected as Encoder 3 has failed: the drive measures an input voltage at this channel that lies outside the permissible limits, so no usable measurement is available from the channel. Depending on how the drive is configured, the same condition can also be output as an alarm (A) or without any reaction (N); for both alternatives the manual specifies no reaction and no acknowledgement.

• The input voltage of the analog sensor is outside the permissible limits.
• Fault value 1: the input voltage is outside the detectable measuring range.
• Fault value 2: the input voltage is outside the measuring range set in p4673 (the voltage per encoder period).
• Fault value 3: the absolute value of the input voltage has exceeded the range limit p4676.

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

The drive stores the fault value in r0949; interpret the value as a decimal number.

• 1 — input voltage outside the 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 here, as a decimal number, which of the three conditions (1, 2 or 3) raised the fault.
• p4673 — analog sensor channel A voltage per encoder period: check this setting when the fault value is 2.
• p4676 — analog sensor range limit threshold: check this setting, and increase it if necessary, when the fault value is 3.

The fault trips OFF1 and can only be acknowledged when pulses are inhibited: bring the drive to a standstill so that the pulse inhibit is active, then acknowledge the fault — after that the drive can be switched on again. When the condition is configured as an alarm or without any reaction, neither a reaction nor an acknowledgement applies.
