Acceleration operation
---
Acceleration/deceleration curves cannot be set for speed control or torque
control. Continuous speed changes using speed control, however, are possi-
ble by setting the Soft Start Acceleration Time and Soft Start Deceleration
Time in the Servo Parameters.
The acceleration/deceleration settings are set for each axis according to the
Servo Parameters for acceleration/deceleration. Set these Servo Parameters
using WRITE/SAVE SERVO PARAMETER before sending operating com-
mands.
Do not change the acceleration/deceleration constants during axis operation
(i.e., while the Busy Flag for the corresponding axis is ON due to execution of
an operating command). Changing parameters while the axis is operating
may result in incorrect positioning or other malfunction.
Acceleration/Deceleration Constants
Parameter name
Linear acceleration 10,000 com-
constant
mand units/s
Linear deceleration 10,000 com-
constant
mand units/s
When using G5-series Servo Drives, one-step linear acceleration/decelera-
tion curves are set using only Pn811 and Pn814.
When the parameter is set to 0, it is taken as 1.
The setting will be used after conversion to unsigned 16-bit data (0 to 65536).
Examples: −32768 is converted to 8000 hex = 32768
−1 is converted to FFFF hex = 65535
