Holding Function of Acceleration/Deceleration

The holding function of the acceleration or deceleration is enabled when a mechanical moment of iner-
tia is large.
The acceleration-hold function is to withhold further acceleration until the motor that is starting its revo-
lution achieves a small enough slip. Use this function when an over current trip happens at the start of
the motor revolution.
The deceleration-hold function is to withhold further deceleration until the motor achieves a small
enough slip. Use this function when an over voltage trip happens during deceleration.
There are two methods of stopping the acceleration or deceleration, and they can be used together.
• Holding automatically at any frequency for any length of hold time.
• Holding by means of the Input terminal function.
Precautions for Correct Use
• The working of this function depends on none of the content of the acceleration curve
selection [AC-03] and that of the deceleration curve selection [AC-04]. This function works for
all the patterns.
• When the acceleration (deceleration) command is switched to deceleration (acceleration)
command while acceleration (deceleration)-hold function is withholding, halt the function and
follow the changed command.
