Timing Chart Of The Point Table Operation - Mitsubishi Electric MELSERVO-J5 User Manual

Timing chart of the point table operation

The unit of the speed data and acceleration data of the point table can be changed with [Pr. PT01.1 Speed/acceleration/
deceleration unit selection]. In the following timing chart, the units are r/min for speed data and ms for acceleration/
deceleration data.
[Point actual value (Obj. 2D69h)] and [M code actual value (Obj. 2D6Ah)] display the previous value until the operation is
completed.
The accuracy of the acceleration/deceleration time and dwell time can be improved by setting [Pr. PT02.7_Internal position
command - Process speed selection] to "1" (high speed).
Single positioning operation (absolute value command method)
When bit 4 (New set-point) of [Controlword (Obj. 6040h)] is turned on while the servo is on and the servo motor is stopped,
positioning operation will be performed.
The following shows the timing chart.

*1 It is disabled even if bit 4 (New set-point) of [Controlword (Obj. 6040h)] is turned on while the servo motor is rotating.
*2 The bit turns on when the droop pulse of the command unit is equal to or less than the setting value of [Pr. PA10 In-position range].
*3 The bit turns on when the command remaining distance is equal to or less than the setting value of [Pr. PT12_Rough match output
range (CRP)].
*4 The bit turns on when S_INP (in-position) is on and command remaining distance is "0".
