1. Outline of mode
Velocity Control Mode
(5) Speed coincidence output (V-COIN)
This signal is output when the motor speed is equal to the speed specified by the
speed command. The motor speed is judged to be coincident with the specified speed
when the difference from the speed command before/after acceleration/deceleration is
within the range specified by Pr4.35 "Speed coincident range" .
• Relevant parameters
Parameter
No.
Pr4.35
Note
For details of these parameters, refer to P.4-6 to P.4-85 "Details of parameter".
(6) Speed command acceleration/deceleration setting function
This function controls the speed by adding acceleration or deceleration instruction in
the driver to the input speed command.
Using this function, you can use the soft start when inputting stepwise speed command
or when using internal speed setup. You can also use S shaped acceleration/decelera-
tion function to minimize shock due to change in speed.

Caution
When the position loop is external to the driver, do not use the acceleration/
deceleration time setting. Set these values to 0.
Note
For details of these parameters, refer to P.4-6 to P.4-85 "Details of parameter".
