A32915 — Encoder 2: Configuration error

The drive signals A32915 because the configuration for encoder 2 is incorrect. Which concrete situation the drive has detected is told by the alarm value that it writes to r2124, interpreted as a decimal number. Depending on the drive configuration, the same condition can also be signalled as a fault (F) or as a message without reaction (N) instead of the alarm.

• The configuration for encoder 2 is incorrect; the alarm value in r2124 (interpret decimal) tells which case applies.
• Both descriptions concern the Sensor Module Encoder 2 and are nearly identical; the description for S120 and S150 additionally lists the alarm values 2 and 3, where the cyclic DQ receive or send telegram is too long and is limited, while the description for G130 and G150 only contains the alarm values 1 and 419.

1. Read the alarm value in r2124 and interpret it as a decimal number to determine which case applies.
2. Alarm value 1: no re-parameterization is permissible between fault and alarm — the remedy is simply that no re-parameterization takes place in this interval.
3. Alarm value 419: reduce the fine resolution (p0419), or deactivate the monitoring via p0437.25 if the complete multiturn range is not required.

• 1 — Re-parameterization between fault/alarm is not permissible.
• 2 — The cyclic DQ receive telegram is too long and is limited (listed for S120 and S150).
• 3 — The cyclic DQ send telegram is too long and is limited (listed for S120 and S150).
• 419 — When the fine resolution Gx_XIST2 is configured, the encoder identifies a maximum possible absolute position actual value (r0483) that can no longer be represented within 32 bits.

• r2124 — alarm value: read it as a decimal number to see which case the drive has detected.
• p0419 — fine resolution of the absolute value Gx_XIST2 (in bits): reduce it when alarm value 419 occurs.
• p0437 — Sensor Module configuration extended: p0437.25 deactivates the monitoring for alarm value 419 when the complete multiturn range is not required.

The alarm does not require an acknowledgement; the remaining task is to correct the encoder 2 configuration as the alarm value indicates. If the drive signals the same condition as a fault instead, the fault must be acknowledged IMMEDIATELY — the reaction specified for it is NONE (IASC/DCBRK), for HLA simply NONE. As a message without reaction (N), neither a reaction nor an acknowledgement applies.
