Note1: The acceleration suspend frequency (f350) should not be set below the starting frequency (f240).
Note2: The deceleration suspend frequency (f352) should not be set below the stop frequency (f243).
Note3: If the output frequency is lowered by a stall prevention function, the acceleration suspend function may be
activated.
• Function
This function suspends acceleration and deceleration when starting and stopping during the transportation
of heavy load by temporarily running the motor at a constant speed according to the delay in braking. It
also prevents the occurrence of overcurrent at starting and slippage at stopping by fixing the timing with
brake.
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.
