Caution
[1] When the controller unit is started, the soft limits are automatically set to 0q for the – soft limit and +359.99q for the +
soft limit in the controller, and accordingly the parameter settings will be ignored. A soft limit error will not occur.
[2] With relative position commands, the actuator will not perform rotational operation by shortcut even when the shortcut
mode is selected.
[3] Push operation cannot be performed. Even if push operation is set by position data, the actuator will still perform
normal rotational operation. In this case, the positioning band will conform to the default positioning band.
[4] In jogging and inching operations, the maximum rotation angle supported in each command is one revolution (up to
360q).
[5] The encoder resolution (deg/pulse) is determined by the gear ratio (or ball screw lead) and encoder pulse count, and
may reach or exceed 0.01 deg/pulse. If the encoder resolution is 0.01 deg/pulse or more, an error will generate
between the position complete position and target position.
