Note:
The signal level is not evaluated unless the following conditions are satisfied:
- Sensor Module properties available (r0459.31 = 1).
- Monitoring active (p0437.31 = 1).
Remedy:
- make sure that the encoder cables and shielding are installed in an EMC-compliant manner.
- check the plug connections and contacts of the encoder cable.
- check the short-circuit of a signal cable with mass or the operating voltage.
- replace the encoder cable.

Encoder 3: Amplitude error track A or B overcontrolled
Message value:
A track: %1, B-track: %2
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
VECTOR_G
Reaction:
OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2)
Acknowledge:
PULSE INHIBIT
Cause:
The amplitude of track A or B for encoder 3 exceeds the permissible tolerance band.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex:
yyyy = Signal level, track B (16 bits with sign).
xxxx = Signal level, track A (16 bits with sign).
The nominal signal level of the encoder must lie in the range 375 mV to 600 mV (500 mV -25/+20 %).
The response threshold is > 750 mV. This fault also occurs if the A/D converter is overcontrolled.
A signal level of 500 mV peak value corresponds to the numerical value 5333 hex = 21299 dec.
Note for Sensor Modules for resolvers (e.g. SMC10):
The nominal signal level is at 2900 mV (2.0 Vrms). The response threshold is > 3582 mV.
A signal level of 2900 mV peak value corresponds to the numerical value 6666 hex = 26214 dec.
Note:
The analog values of the amplitude error are not measured at the same time with the hardware fault output by the
Sensor Module.
Remedy:
- check that the encoder cables and shielding are routed in compliance with EMC.
- replace the encoder or encoder cable.

Encoder 3: Amplitude AB too high
Message value:
Amplitude: %1, Angle: %2
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
VECTOR_G
Reaction:
OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2)
Acknowledge:
PULSE INHIBIT
Cause:
The amplitude (root of A^2 + B^2 or |A| + |B|) for encoder 3 exceeds the permissible tolerance.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex:
yyyy = Angle
xxxx = Amplitude, i.e. root from A^2 + B^2 (16 bits without sign)
The nominal signal level of the encoder must lie in the range 375 mV to 600 mV (500 mV -25/+20 %).
The response threshold for (|A| + |B|) is > 1120 mV or the root of (A^2 + B^2) > 955 mV.
A signal level of 500 mV peak value corresponds to the numerical value of 299A hex = 10650 dec.
The angle 0 ... FFFF hex corresponds to 0 ... 360 degrees of the fine position. Zero degrees is present at the
negative zero crossover of track B.
