6.3.4.2. Jogging via RS-232C Communication
The following shows procedures of a typical jogging operation via RS-232C communication.
When a jogging operation is run via RS-232C communication, regular carriage return after the
jogging is started, is strongly recommended, considering a communication failure due to an
accident, such as disconnection of cables.

1) Turn on the Motor servo by the input SVON (Servo on).
2) The output SVST (Servo state) is closed when the Motor servo is on.
3) Input the command JG/PL (Jog direction, plus direction).
The Motor starts jogging operation, following the parameter values of JA (Jog
acceleration), JB (Jog deceleration) and JV (Jog velocity).
◊ Input the command JG/MI for a jogging in the minus direction.
◊ Input a carriage return (0Dh) following the command JG within 0.5 seconds. When
input of the carriage return stops, the Motor decelerates and stops.
4) The output BUSY (In-operation) is closed during the jogging operation, and the output
IPOS (In-position) is open.
5) When the duration of carriage return exceeds 0.5 seconds, the Motor starts to
decelerate.
6) The output BUSY opens at the completion of inputting the internal command for
deceleration. The output IPOS remains open at this time, since the jogging is started
from the position at where the prior positioning is completed.
