Acceleration/deceleration suspend function
: Acceleration/deceleration
suspend function
: Acceleration suspend frequency
: Acceleration suspend time
• Function
Using these parameters, acceleration or deceleration can be suspended to let the motor run at a constant
speed. There are two ways to suspend acceleration or deceleration: suspending it automatically by setting
the suspend frequency and time using parameters, and suspending it by means of a signal from an
external control device.
These parameters are useful in starting and stopping transfer equipment, textile machines (winders), and
so on.

Acceleration/deceleration suspend function
Acceleration suspend frequency
Acceleration suspend time
Deceleration suspend frequency
Deceleration suspend time
1) To suspend acceleration or deceleration automatically
Set the desired frequency with or and the desired time with or , and then set
to .
When the frequency set is reached, the motor stops accelerating or decelerating to rotate at a constant speed.
Output frequency [Hz]
2) To suspend acceleration or deceleration by means of a signal from an external control device
Set for the desired external signal input terminal. As long as ON signals are output, the motor continues to
rotate at a constant speed.
Output frequency [Hz]
Terminal board input
Ex.) When using the S4 terminal as the acceleration/deceleration suspend terminal
