Acceleration/deceleration Time Variables ACCEL and DECEL
When you directly control the acceleration/deceleration time of the frequency reference by the
DriveProgramming function, set the inverter's parameter Acceleration/Deceleration Time Input Type
(AC-01) to 04 (DriveProgramming) to enable the acceleration time variable ACCEL and the
deceleration time variable DECEL.
Function
variable
ACCEL Acceleration time variable 0 to 360,000
DECEL Deceleration time variable
• The acceleration time variable ACCEL and the deceleration time variable DECEL are enabled only
when you set the Acceleration/Deceleration Time Input Type (AC-01) to 04 (DriveProgramming).
• Only when the program is started for the first time after the power supply is turned ON, the value set
in the inverter's acceleration/deceleration time parameters are set for the DriveProgramming's accel-
eration time variable ACCEL and deceleration time variable DECEL.
The acceleration/deceleration time for the 1st/2nd Acceleration Time 1 (AC120/AC220) and the
1st/2nd Deceleration Time 1 (AC122/AC222) are set according to the 1st/2nd control selection.
• The data set in the acceleration time variable ACCEL and deceleration time variable DECEL are not
saved in the EEPROM.
• The internal processing for the acceleration/deceleration time is performed in 40 ms cycles. Even if
the value of the acceleration time variable ACCEL or the deceleration time variable DECEL is
changed in the program, it takes up to 40 ms until the change is reflected in operation.
• In the following cases, the data that is set in the program is not reflected and the previously set data
is used for operation: the data set for the acceleration time variable ACCEL or the deceleration time
variable DECEL is out of range, or 0 is set for the 3G3RX2 Series Inverter.
Precautions for Correct Use
When the DriveProgramming program is stopped, the data of the acceleration time variable
ACCEL and deceleration time variable DECEL before the program stop is retained. When the
program execution is started again, the process begins with the retained data.
