SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
Note:
For SMC30 (order no.. 6SL3055-0AA00-5CA0 and 6SL3055-0AA00-5CA1 only), CUA32, and CU310, the following
applies:
A square-wave encoder without track R is used and track monitoring (p0405.2 = 1) is activated.
Remedy:
- Check the encoder/cable.
- Does the encoder supply signals and the associated inverted signals?
Note:
For SMC30 (order no. 6SL3055-0AA00-5CA0 and 6SL3055-0AA00-5CA1 only), the following applies:
- check the setting of p0405 (p0405.2 = 1 is only possible if the encoder is connected at X520).
For a square-wave encoder without track R, the following jumpers must be set for the connection at X520 (SMC30)
or X23 (CUA32, CU310):
- pin 10 (reference signal R) <--> pin 7 (encoder power supply, ground)
- pin 11 (reference signal R inverted) <--> pin 4 (encoder power supply)

Encoder 2: Speed difference outside the tolerance range
Message value:
%1
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge:
PULSE INHIBIT
Cause:
For an HTL/TTL encoder, the speed difference has exceeded the value in p0492 over several sampling cycles.
The change to the averaged speed actual value - if applicable - is monitored in the current controller sampling time.
Fault value (r0949, decimal interpretation):
Only for internal Siemens troubleshooting.
See also: p0492 (Square-wave encoder, maximum speed difference per sampling cycle)
Remedy:
- check the tachometer feeder cable for interruptions.
- check the grounding of the tachometer shielding.
- if required, increase the maximum speed difference per sampling cycle (p0492).

F32120 (N, A)
Encoder 2: Power supply voltage fault
Message value:
Fault cause: %1 bin
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge:
PULSE INHIBIT
Cause:
A power supply fault was detected for encoder 2.
Fault value (r0949, interpret binary):
Bit 0: Undervoltage condition on the sense line.
Bit 1: Overcurrent condition for the encoder power supply.
Bit 2: Overcurrent condition for encoder power supply on cable resolver excitation negative.
Bit 3: Overcurrent condition for encoder power supply on cable resolver excitation positive.
Note:
If the encoder cables 6FX2002-2EQ00-.... and 6FX2002-2CH00-.... are interchanged, this can result in the encoder
being destroyed because the pins of the operating voltage are reversed.
Remedy:
Re fault value, bit 0 = 1:
- correct encoder cable connected?
- check the plug connections of the encoder cable.
- SMC30: Check the parameterization (p0404.22).
Re fault value, bit 1 = 1:
- correct encoder cable connected?
- replace the encoder or encoder cable
