Acceleration/Deceleration Stop Function

This function causes the inverter stop accelerating/decelerating temporarily and start running at a con-
stant speed at the frequency output at that time.
If the moment of inertia of a load machine is large, you can use it, for example, to have the motor wait
until the amount of motor slip during acceleration/deceleration becomes small. You can use it also to
prevent an overcurrent/overvoltage trip during acceleration/deceleration.
This function works independently of the Acceleration/Deceleration Pattern Selection (A097/A098) set-
ting. It is activated for all acceleration/deceleration patterns by the frequency reference input via the
analog input signal or the optional Digital Operator's volume control (VR).
There are two acceleration/deceleration stop methods as follows, which can be used in conjunction
with each other.
• Stopping automatically when the specified frequency/stop time is reached
• Stopping by inputting the terminal HLD (83: Retain output frequency) set in the Multi-function Input
S1 to S7 Selection (C001 to C007)
Using this function prolongs the acceleration/deceleration time configured by the F001/F202 and
F003/F203 settings for the duration of the stop time caused by this function.
