Chapter 7 Usage of Various Functions

8)JOG Operation (POSJOG : Level input)

(1)JOG operation

Carries out the positioning control by Jog command(POSJOG).

Carries out the monitoring when the positioning acts by JOG command and the position address is changed.

This is used when acting without origin determination.

(2)Acceleration/Deceleration Processing and Jog speed

(A)The acceleration/deceleration processing is controlled based on the setting time of JOG acceleration/ deceleration time from parameter setting.

Jog high speed operation : operation pattern with acceleration/deceleration

Speed

Time

Jog low speed operation : operation pattern without acceleration/deceleration

Speed

Time

(B)If speed operand of POSJOG command as device not constant, JOG speed can be changed from low speed to high speed or high speed to low speed during operation

(C)If Jog speed is set out of the setting range, error will occur and the operation does not work.

Setting range

Jog high speed operation

5100,000 pps

 

 

Jog low speed operation

5100,000 pps

(Setting unit :1pps)

9)Speed Override Command(POSSOR : Rising edge ))

This is used to change the operation speed from operation data of step no. in operation of each axis

This command is used only in Acceleration and Constant speed section from operation pattern.

Setting range is 5 ~ 100,000

This command can be used in position control and speed control.

Remark

If POSSOR is executed in deceleration section, error code H44 will occur and continues operation
