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 (M(P).CHGV/D(P).CHGV)).
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.
Setting value
Details
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.
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.
Setting value
Details
1 to 8388608 [ms]
If a speed change request is executed when the acceleration/deceleration time change enable device is ON, speed change is executed
by changing the acceleration time to the setting value
Other than above
Acceleration time change is disabled, and speed change is maintained at the current acceleration time.
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.
Setting value
Details
1 to 8388608 [ms]
If a speed change request is executed when the acceleration/deceleration time change enable device is ON, speed change is executed
by changing the deceleration time to the setting value.
Other than above
Deceleration time change is disabled, and speed change is maintained at the current deceleration time.
• When the setting of acceleration/deceleration time change enable device is omitted, change of acceleration/
deceleration time at a speed change request is not executed. When changing acceleration/deceleration
time at a speed change, set this parameter.
• When the setting of new acceleration time value device and new deceleration time value device is omitted,
change of acceleration/deceleration time of the omitted devices is not executed.
