13. POSITIONING MODE
13.5 Manual operation mode
For machine adjustment, home position matching, etc., JOG operation or a manual pulse generator may be
used to make a motion to any position.
13.5.1 JOG operation
(1) Setting
Set the input device and parameters as follows according to the purpose of use. In this case, the point table
No./program No. selection 1 to 3 (DI0 to DI2) are invalid.
Item Device/Parameter used Description
Manual operation mode selection Automatic/manual selection (MD0) Turn MD0 OFF.
Servo motor rotation direction Parameter No. PA14 Refer to (2) in this section.
JOG speed Parameter No. PE13 Set the speed of the servo motor.
Acceleration/deceleration time
constant
Parameter No. PE07 Set the acceleration/deceleration time constants.
S-pattern acceleration/deceleration
time constant
Parameter No. PC03
Set the S-pattern acceleration/deceleration time
constant.
(2) Servo motor rotation direction
Parameter No. PA14 setting

(3) Operation
By turning ST1 ON, operation is performed under the conditions of the JOG speed set in the parameter and
the acceleration and deceleration time constants in set parameter No. PE07. For the rotation direction, refer
to (2) in this section. By turning ST2 ON, the servo motor rotates in the reverse direction to forward rotation
start (ST1).
