Precautions - Mitsubishi Electric MELSEC Q Series User Manual

10 FUNCTION DETAILS

10.15.2 Precautions

A "Warning code 11012" or "Warning code 11013" will occur and the
acceleration/deceleration time change does not execute in the following cases.
• In operation stop
• In decerelation
• In OPR
• In current value change
• In pausing
(2) When the speed change function is used simultaneously
When this function and the speed change function are simultaneously used, the
speed change is executed after the acceleration/deceleration time change.

(1) The new acceleration/deceleration time is valid in execution of the positioning
data for which the acceleration/deceleration was changed. Even if the
acceleration/deceleration is changed to the new acceleration/deceleration by
executing the acceleration/deceleration change at continuous positioning control
and continuous path control, the control is executed with the previously set
acceleration/deceleration at the changeover to the next positioning data.
(2) Even if the acceleration/deceleration time change is set to disable after the new
acceleration/deceleration time is validated, the positioning data for which the new
acceleration/deceleration time was validated will continue to be controlled with
that value. (The next positioning data will be controlled with the previously set
acceleration/deceleration time.)
