Accelerating And Decelerating Heavy Loads (Dwell Function) - YASKAWA CIMR-F7A Instruction Manual

Accelerating and Decelerating Heavy Loads (Dwell Function)

The dwell function stores the output frequency when starting or stopping heavy loads. By temporarily storing
the output frequency, you can prevent the motor from stalling. When using the dwell function, you must select
a deceleration stop. Set b1-03 (Stopping Method Selection) to 0.
