33: Acceleration time constant (speed)
Function
This function sets the time in which the motor is accelerated from 0 r/min to the maximum rotation speed
during speed control.
For external speed commands, when a speed command faster than the setting value is entered, the
setting value has higher priority; when a speed command slower than the setting value is entered, the
speed command has higher priority.
For internal speed commands, acceleration is performed based on the setting value.

34: Deceleration time constant (speed)
Function
This function sets the time in which the motor is decelerated from the motor maximum rotation speed to
0 r/min during speed control.
For external speed commands, when a speed command faster than the setting value is entered, the
setting value has higher priority; when a speed command slower than the setting value is entered, the
speed command has higher priority.
For internal speed commands, deceleration is performed based on the setting value.

35: Analog command A/D value (Mid)
(Speed / torque)
Function
This function sets the offset value when the analog command is 0V (a command value to stop the motor).
Enter 0V to the analog command, and set the analog input voltage value in the value monitor of the state
display window of communication software PSF-520. For details, refer to a separate document,
