In speed or position control, the speed setting will be that for manual feed.
In torque control, the setting value specified in PA1_26 (Max. rotation speed) is used as the speed
limit when PA2_56 (torque control speed limit selection) is set to "0".
When PA2_56 (torque control speed limit selection) is set to "1", the speed limit values in the
following table will be valid.
The speed setting values (speed limit values when performing torque control) are as shown in the
following table with input signal (CONT signal): multi-step speed selection 1 [X1] to 3 [X3]
combination.
