If the start signal for movement to position 2 is input while the actuator is moving to position 1 in
the push & hold mode, the actuator will move to the position 10 mm from where it was when the
input signal was input.

(3) Cumulative errors due to repeated incremental moves

Position data is recognized only as a multiple of the minimum resolution. The minimum resolution is
determined by the lead and the number of encoder pulses. Therefore, a margin of error may occur between
the entered position value and the actual movement of the actuator. If an incremental move is repeated, this
error will accumulate.
The maximum error range for each actuator type is shown below:
