11.7.3 Parameter for acceleration/deceleration control

Reference increment = pulse cycle (address A) /reference increment setting

Pulse cycle of each step = pulse cycle (address A) + reference increment x pulse cycle increment table

Time of each step = pulse cycle of each step x selected data table (number of pulses)
