The parameter is enabled for acceleration and deceleration motions under speed control and position
control (homing and manual position control operation) and for speed limit control with torque control.
The parameter is enabled for acceleration and deceleration motions uder speed control and position
control (positioning, homing and manual position control operation).
Acceleration and deceleration follow these parameters during profile operation, too.
These parameters are disabled during pulse operation.
The acceleration/deceleration time setting indicates the time from 0 (zero) [r/min] to 2000 [r/min].
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 (CONT signal). Selection follows the table below.
The deceleration time with a load in a carrier drive mechanism can be specified separately from that
without a load.
ACC0 (14) Acceleration time Deceleration time
OFF PA1_37 PA1_38
ON PA1_39 PA1_40
Use PA1_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 PA1_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 PA1_36 to enable PA1_37
through PA1_40. At the time of homing and manual operation, PA1_37 through PA1_40 are enabled
without relations to the setting of PA1_36.
