(3) It can be controlled in the real mode only for axis which "control unit is [degree]
and stroke limit is invalid ("upper stroke limit value" equal to "lower stroke limit
value")". If it is started for axis which "control unit is except [degree] or stroke limit
is not invalid", a minor error (error code: 130) occurs and it does not start.
And, if it is started for the virtual servo motor axis in the virtual mode, a servo
program setting error (error code: 905) occurs and it does not start. (It can be
started for real mode axis.)
