Estimating Times and Pulses for Acceleration/Deceleration
Appendix B
Using the above abbreviations, the number of pulses for the acceleration and deceleration time can be calcu-
lated as follows:
Example
In this example, numeric settings are entered for the operation pattern shown below.
Maximum speed setting:
V

= 35,000 pps
Acceleration time setting:
