Note
(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.
Title Range Unit Function
Pr4.35 Speed coincidence
range
10 to 20000 r/min Set the speed coincidence (V-COIN)
output detection timing.
For details of these parameters, refer to P.4-39 “Details of parameter”.
Caution
Note
(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.
• Relevant parameters
Parameter
No.
Title Range Unit Function
Pr3.12 Acceleration time
setup
0 to 10000
ms/
(1000r/min)
Set up acceleration processing time in
response to the speed command input.
Pr3.13
Deceleration time
setup
0 to 10000
ms/
(1000r/min)
Set up deceleration processing time in
response to the speed command input.
Pr3.14
Sigmoid acceleration/
deceleration time setup 0 to 1000
ms
Set S-curve time for acceleration/
deceleration process when the speed
command is applied.
When the position loop is external to the driver, do not use the acceleration/
deceleration time setting. Set these values to 0.
For details of these parameters, refer to P.4-26 and 27 “Details of parameter”.
