Acceleration and Deceleration Operations
Section 7-4
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.
7-4-2
Acceleration/Deceleration Settings
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.
G5-series Servo Parameters
Acceleration/Deceleration Constants
Note
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
G-series Servo Parameters
Acceleration/Deceleration Constants
Note
When using G-series Servo Drives, one-step linear acceleration/deceleration
curves are set using only Pn107 and Pn10A.
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
