SINAMICS S List Manual (LH1), 07/2007
SMC20:
A signal level of 500 mV peak value corresponds to the numerical value 299A hex = 10650 dec.
SMC10:
A signal level of 2900 mV peak value corresponds to the numerical value 3333 hex = 13107 dec.
High word:
Angle 0 to 65535 corresponds to 0 to 360 degrees of the fine position. Zero degrees is at the negative zero crossover
of track B.
Remedy: - check the speed range, frequency characteristic (amplitude characteristic) of the measuring equipment is not suf-
ficient for the speed range.
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder or encoder cable.
- check the Sensor Module (e.g. contacts).
- dirty code disk
- aged lighting system.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon A: NONE
Acknowl. upon A: NONE
A33418 (F, N) Encoder 3: Speed difference per sampling rate exceeded
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: For an HTL/TTL encoder, the speed difference between two sampling cycles has exceeded the value in p0492.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - check the tachometer feeder cable for interruptions.
- check the grounding of the tachometer shielding.
- if required, increase the setting of p0492.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
A33419 (F, N) Encoder 3: Track A or B outside the tolerance range
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The amplitude, phase or offset correction for track A or B is at the limit.
Amplitude error correction: Amplitude B / Amplitude A = 0.78 ... 1.27
Phase: <84 degrees or >96 degrees
SMC20: Offset correction: +/-140 mV
SMC10: Offset correction: +/-650 mV
Alarm value (r2124, interpret hexadecimal):
xxx1: Minimum of the offset correction, track B
xxx2: Maximum of the offset correction, track B
xx1x: Minimum of the offset correction, track A
xx2x: Maximum of the offset correction, track A
x1xx: Minimum of the amplitude correction, track B/A
x2xx: Maximum of the amplitude correction, track B/A
1xxx: Minimum of the phase error correction
2xxx: Maximum of the phase error correction
