Acceleration/Deceleration Time Change Parameter - Mitsubishi Electric MELSEC Q Series Programming Manual

4 PARAMETERS FOR POSITIONING CONTROL

4.4.2 Acceleration/deceleration time change parameter

The acceleration/deceleration time change parameter arbitrarily changes the
acceleration/deceleration time at speed change, when changing speed with the Motion
dedicated function (CHGV) of Motion SFC program (and also the Motion dedicated
PLC instruction (D(P). CHGV)).
(1) Acceleration/deceleration time change enable device
Set the device to enable the change of acceleration/deceleration time at a speed
change request.
The following describes the operation for ON and OFF of the acceleration/
deceleration time change enable device.
• ON ............ Speed change is executed at a speed change request by changing
the acceleration/deceleration time values in the new acceleration
time value device and new deceleration time value device.
• OFF .......... Does not change acceleration/deceleration time at a speed change
request.
(2) New acceleration time value device
Set the device to set the change value when changing the acceleration time at a
speed change request.
The following change values are set in the new acceleration time value device.
• 0..................................... Acceleration time change is disabled, and speed
• 1 to 65535[ms] .............. If a speed change request is executed when the
(3) New deceleration time value device
Set the device to set the change value when changing the deceleration time at a
speed change request.
The following change values are set in the new deceleration time value device.
• 0..................................... Deceleration time change is disabled, and speed
• 1 to 65535[ms] .............. If a speed change request is executed when the
