Incorrect resolver connection Check motor connections
No electrical power on cylinder motor
Check voltage, main switch status and fuses status above
the servoamplifier. Check that the servoamplifier authorizes
cylinder move and cylinder motor torque on
Incorrect definition of cylinder move
Check that all move parameters (target position, speed and

stops immediately with
fault servoamplifier
Incorrect motor connection Check motor connections
Incorrect resolver connection Check motor connections
Servoamplifier fault
Read the technical documentation of the servo-
amplifier. In function of fault number, possible causes are
suggested with associated solutions.
Cylinder doesn’t move
in correct direction
Incorrect motor/resolver connection or incorrect
servoamplifier parameter
Check motor connections or change direction of movement
in the servoamplifier parameters
Cylinder vibrates in stop

AR33543-0223 corresponds to cylinder no 223 with 33543
design file number).
• Malfunction nature and duration (continuous? sometimes?
(estimated frequency?), malfunction occurs only one
time?).
• When and in what conditions the malfunction occurs (a de-
tailed description is required).
• If possible, take pictures or screen captures to illustrate
malfunction description.
