|Electric Actuators

For an LECA6 series controller, what are the possible causes of the actuator moving about 10 mm when the servo is turned ON after turning the power ON?

The servo motor (24 VDC) type actuator performs an operation to check the Z-phase of the motor at the first servo ON after the power is turned ON.
Since this Z-phase signal is a signal that is output once per motor, the motor moves about 1 to 2 rotations during this operation.
For example, the LEFS25AA is an actuator with a lead of 12 mm, so it moves about 12 to 24 mm during this operation.
