SLX.Er Solutions Module slot X trip: Solutions Module in slot X has detected a fault
202,207,212
Feedback module category
Check value in Pr 15/16.50. The following table lists the possible error codes for the SM-Universal Encoder Plus, SM-Encoder Plus
and SM-Resolver. See the Diagnostics section in the relevant Solutions Module User Guide for more information.
Trip Diagnosis
Error code Module Trip Description Diagnostic
0 All No trip No fault detected
1
SM-Universal
Encoder Plus
Encoder power supply overload
Check encoder power supply wiring and encoder current
requirement Maximum current = 200 mA @ 15 V, or 300 mA
@ 8 V and 5 V
SM-Resolver Excitation output short circuit Check the excitation output wiring.
2
SM-Universal
Encoder Plus &
SM-Resolver
Wire break
Check cable continuity
Check wiring of feedback signals is correct
Check supply voltage or excitation output level
Replace feedback device
3

Checksum or CRC error
Check the encoder signal for noise
Check the encoder cable shielding
6
SM-Universal
Encoder Plus
Encoder has indicated an error Replace encoder
7
SM-Universal
Encoder Plus
Initialisation failed
Check the correct encoder type is entered into Pr 15 / 16 / 17.15
Check encoder wiring
Check supply voltage level
Replace feedback device
8
SM-Universal
Encoder Plus
Auto configuration on power up
has been requested and failed
Change the setting of Pr 15/16/17.18 and manually enter
the number of turns (Pr 15/16/17.09) and the equivalent
number of lines per revolution (Pr 15/16/17.10)
9
SM-Universal
Encoder Plus

Encoder Plus
Failure of the sincos analog
position alignment during encoder
initialization
Check encoder cable shield.
Examine sine and cosine signals for noise.
SM-Resolver Poles not compatible with motor
Check that the correct number of resolver poles has been
set in Pr 15/16/17.15.
12
SM-Universal
Encoder Plus
Encoder type could not be
identified during auto-configuration
