Message value: %1 Drive object: All objects Reaction: A_INFEED: NONE SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) Acknowledge: PULSE INHIBIT SINAMICS-Alarms Cause: The error for track C/D is greater than +/-15 ° mechanica l or +/-60 ° electrical or the error for the Hall signals is greater than +/-60 ° electrical. One period of track C/D corresponds to 360 ° mechanical. One period of the Hall signal co rresponds to 360 ° electrical. The monitoring responds if, for exam ple, Hall sensors are connected as equivalent for the C/D tracks with the incorrect rotational sense or supply values that are not accurate enough. After the fine synchronization using one referenc e mark or 2 reference marks for distance-coded encoders, this fault is no longer initiated, but instead, Alarm A33429. Fault value (r0949, interpret decimal): For track C/D, the following applies: Measured deviation as mechanica l angle (16 bits with sign, 182 dec corresponds to 1 °). For Hall signals, the following applies: Measured deviation as el ectrical angle (16 bits with si gn, 182 dec corresponds to 1 °). Remedy: - track C or D not connected. - correct the direction of rotation of the Hall s ensor possibly connected as equivalent for track C/D. - check that the encoder cables are routed in compliance with EMC. - check the adjustment of the Hall sensor.
