SINAMICS S List Manual (LH1), 07/2007
F33125 (N, A)
Encoder 1: Amplitude error track A or B overcontrolled
Drive object:
All objects
Reaction:
A_INFEED: NONE
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge:
PULSE INHIBIT
Cause:
The amplitude (track A or B) does not lie within the tolerance bandwidth (software monitoring function).
SMC20:
The nominal signal level of the encoder must lie in the range 375 mV to 600 mV (500 mV -25 % / +20 %).
On the other hand, the response threshold is > 760 mV (frequency characteristic).
SMC10:
The nominal signal level is at 2900 mV (2.0 Vrms). The response threshold is > 3582 mV.
Fault value (r0949, interpret decimal):
Low word:
Signal level, track A (16 bits with sign).
High word:
Signal level, track B (16 bits with sign).
SMC20:
A signal level of 500 mV peak value corresponds to the numerical value 5333 hex = 21299 dec.
SMC10:
A signal level of 2900 mV peak value corresponds to the numerical value 6666 hex = 26214 dec.

Remedy:
- check that the encoder cables are routed in compliance with EMC.
- replace the encoder or encoder cable.
- with measuring systems without their own bearing system: Adjust the scanning head and check the bearing system
of the measuring wheel.
Reaction upon N:

F33129 (N, A)
Encoder 3: Position difference, hall sensor/track C/D and A/B too large
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
Cause:
The error for track C/D is greater than +/-15 ° mechanical 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 corresponds to 360 ° electrical.
The monitoring responds if, for example, Hall sensors are connected as equivalent for the C/D tracks with the incor-
rect rotational sense or supply values that are not accurate enough.
After the fine synchronization using one reference 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 mechanical angle (16 bits with sign, 182 dec corresponds to 1 °).
For Hall signals, the following applies:
Measured deviation as electrical angle (16 bits with sign, 182 dec corresponds to 1 °).
Remedy:
- track C or D not connected.
- correct the direction of rotation of the Hall sensor 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.
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
