Acceleration time 2 and deceleration time 2 are enabled while the "ACC0" selection signal remains turned
on.
ACC0 can be turned on or off at any time and the acceleration time and deceleration time are similarly
changed.
ACC0 is assigned to an input signal (EI signal). Selection follows the table below.

Use P1.36 (acceleration / deceleration selection at speed control) to select acceleration/deceleration of
speed control.
To perform position control at the host control unit and to perform speed control at the servo system, enter
"0" to P1.36 (control method to output analog speed command voltage at host control unit).
To perform speed control independently in the servo system, enter "1" to P1.36 to enable P1.37 through
P1.40. To perform position control independently in the servo system, P1.37 through P1.40 are enabled
regardless of the setting of P1.36.
The acceleration and deceleration of speed limit under torque control is in accord with the parameter P1.36.
Acceleration and deceleration occurs according to the table shown above if P1.36 is set at "1" (enable).
If the acceleration/deceleration time data is “0” during operation with position data, the values specified in
these parameters are enabled.
