11.7 Address 9

This address is used to set parameters for acceleration/deceleration control, the pulse multiplication factor.

By setting the parameters for acceleration/deceleration control, the pulse cycle can be gradually changed while the

motor is accelerated or decelerated, so that step out of the motor can prevent.

By setting the pulse number multiplication factor to a value other than 1, the number of pulses can be extended in

combination with the number of pulses set by address B. If the default value is not changed, the motor is driven

without being accelerated or decelerated, and under the condition that the pulse number multiplication factor is 1.

11.7.1 Pulse number multiplication factor

D1 and D0 are used to set the pulse number multiplication factor.

By setting a multiplication factor, if the number of motor pulses set at address B is insufficient, the number of pulses

can be extended maintaining 64 steps/cycle.
