Note 1. When the rest of command travel distance is other than "0", ST1 (Forward rotation start) will not be accepted. Refer to section
6.4.5 (1).
2. SIG and RT (Second acceleration/deceleration selection) will not be accepted during operation. Selection of the servo motor
speed and acceleration/deceleration time constants will be enabled by on-edge of ST1 (Forward rotation start). However, when
the rest of command travel distance is other than "0", turning on ST1 (Forward rotation start) will not be enabled.
3. Counting will start when the rest of command travel distance becomes "0".
4. When MEND (Travel completion) is off, the station position outputs will be "0" (all off).
5. For MR-J4-03A6-RJ servo amplifiers, up to six points of DO are available; therefore, PS0 to PS7 cannot be outputted
simultaneously.
