Unable to read main or
auxiliary encoder input.
The encoder works
correctly when swapped
with another encoder input.
1. Wrong encoder
connections.
2. Encoder configuration
incorrect.
3. Encoder input or
controller is damaged
Check encoder wiring. For single
ended encoders (MA+ and MB+
only) do not make any connections
to the MA- and MB- inputs.
Check CE command
Contact Galil
Encoder Position Drifts
Swapping cables fixes the
problem
1. Poor Connections /
intermittent cable
Review all connections and
connector contacts.
Encoder Position Drifts
Significant noise can be
seen on MA+ and / or MB+
encoder signals
1. Noise
Shield encoder cables
Avoid placing power cables near
encoder cables
Avoid Ground Loops
Use differential encoders
Use +/-12V encoders
Stability
SYMPTOM
DIAGNOSIS
CAUSE
REMEDY
Servo motor runs away
when the loop is closed.
Reversed Motor Type
corrects situation (MT -1)
1. Wrong feedback
polarity.
Reverse Motor or Encoder Wiring
(remember to set Motor Type back to
default value: MT 1)
Motor oscillates.
2. Too high gain or
too little damping.
Decrease KI and KP. Increase KD.
