About us
Definition
Acceleration is used to increase the speed of an axis along a movement profile. Acceleration values are limited to the value of the maximum acceleration.
Deceleration is used to reduce the speed of an axis along a movement profile. Deceleration values are limited to the maximum deceleration value.
The acceleration/deceleration ramp is applied to movement commands for that axis.
Movement Planning
The trajectory generator uses this acceleration/deceleration to calculate the commands sent to the controlled drive. The controlled drive has independent acceleration/deceleration parameters. For homing, the drive uses the SERCOS® standard homing acceleration/deceleration parameter (identification number - IDN S-0-0042). For emergency stops, the drive may use a special deceleration value. (See your drive's Proprietary (P) IDN list.)
Maximum Acceleration
The servo drive's maximum acceleration/deceleration limit (SERCOS® Standard IDN S-0-0138 Bipolar Acceleration Limit or IDN S-0-0136 Positive Acceleration Limit) must be greater than the movement controller's AccelMax and DecelMax parameters.
