Control Techniques SM-encoder plus User Manual page 33

Any trip can be initiated by writing the relevant trip number to Pr 10.38. If any trips
shown as user trips are initiated the trip string is "txxx", where xxx is the trip number.
Trips can be reset after 1.0s if the cause of the trip has been rectified.
A full list of drive trips can be found in the Unidrive SP User Guide.

Enc1 Drive encoder trip: Encoder power supply overload
Check encoder power supply wiring and encoder current requirement

Maximum current = 200mA @ 15V or 300mA @ 8V and 5V
PS.24V 24V internal power supply overload
The total user load of the drive and Solutions Modules has exceeded the internal 24V
power supply limit.
The user load consists of the drive's digital outputs plus the SM-I/O Plus digital
outputs, or the drive's main encoder supply plus the SM-Universal Encoder Plus

encoder supply.
• Reduce load and reset
• Provide an external 24V >50W power supply
• Remove any Solutions Modules and reset

# - If the terminations are not enabled on the A, B or Z inputs the wire break system will
not operate. (Note that as default the Z input terminations are disabled to disable wire
break detection on this input.)
Encoder initialisation will occur when trips 1 to 8 are reset.
It is important that a break in the connections between the drive and the position
feedback device can be detected. This feature is provided either directly or indirectly
as listed.
When the drive is reset this parameter is cleared for the relevant Solutions Module
