Electric cylinder is operating but is not
up to rated speeds/forces. Motor phase are wired incorrectly or
in incorrect order. Verify correct motor power wiring.
Amplifier is improperly tuned. Check gain settings.
Amplifier is set up improperly for
electric cylinder used. Check amplifier setting for number of poles,
voltage, current, resistance, inductance,
inertia, and other motor settings.
Actuator cannot move load. Force is too large for the capacity of
the electric cylinder or to much
friction is present. Verify force requirements.
Misalignment of piston rod to load. Verify load alignment.
Amplifier has too low current
capacity or is limited to too low of
current capacity. Verify correct amplifier and settings.
Electric cylinder moves or vibrates
when piston rod is in motion. Loose mounting. Check electric cylinder mounting.
Amplifier is improperly tuned-
wrong gain setting. Tune amplifier.
Actuator is overheating. Duty cycle is higher than actuator
rating. Verify load forces and electric cylinder rating.
Actuator is being operated outside
of continuous rating. Adjust operation to be within continuous
operation rating.
Amplifier is poorly tuned, causing
excessive current to be applied to
motor. Check gain settings.
