F32502Encoder 2: Encoder with measuring gear without valid signals

What it means

F32502 reports that the encoder configured as Encoder 2 — an encoder with a mounted measuring gear — no longer provides any valid signals, so the drive is left without a usable actual value from this encoder. The message is assigned to the Sensor Module Encoder 2. Depending on how the drive is configured, the same condition can also be issued as an alarm or with no reaction at all.

Why it appears

  • The encoder with measuring gear connected as Encoder 2 has stopped delivering any valid signals.

What to check

  1. Make certain that every encoder fitted with its measuring gear delivers valid actual values while the drive is in operation.

Acknowledging and restarting

The message is acknowledged immediately; the drive trips on a fault and can only be taken back into operation once the condition has been remedied and the message acknowledged. When the same condition is issued as an alarm or with no reaction, neither a reaction nor an acknowledgement takes place (NONE).

The same on every family

Every manual that describes F32502 gives it the same reaction, acknowledgement and message class.

Questions technicians ask

What does fault F32502 mean on a SINAMICS drive?

It means that Encoder 2, an encoder with a mounted measuring gear, no longer provides any valid signals, so the drive receives no usable actual value from this encoder.

What should I check when F32502 appears?

The remedy is to ensure that all encoders with mounted measuring gear provide valid actual values in operation. Once that is the case, acknowledge the message and restart the drive.

How is F32502 acknowledged?

The fault is acknowledged immediately. In its variants as an alarm or without a reaction, no acknowledgement and no reaction are specified.

Can F32502 also appear as an alarm?

Yes — the same condition can also be issued as an alarm or with no reaction, depending on the drive's configuration.
