CHV180 series frequency inverter special for elevator          Detailed function description 
.43. 
  Feedback terminals signal of forced deceleration switch action is effective. 
  During run-up process,  it  comes  across  up-forcing switch,  or  during run-down 
process, it comes across down-forcing switch. 
  Current  running  speed  is  greater  than  the  detected  speed  of  corresponding 
forced deceleration switch, if not; the inverter will keep the current running state. 
  After the forcing decelerating action, the speed will be reduced continuously with 
P1.23, P1.25, and P1.27 until 0. 
Note: 
1)The  priority  of  forced  deceleration  is  only  less  than  the  priority  of  forcing 
slow–down  to  stop,  the  priority  is  like  this:  forced  deceleration  1  >  forced 
deceleration 2 > forced deceleration 3. 
2)  The  100%  of  forced  deceleration  detection  value  is  corresponding  with 
elevator rated speed (P0.02). 
3) It will not response the forced deceleration during motor autotuning.

0: Decelerate to stop 
When  the  stop  command  takes  effect,  the  inverter  decreases  the  output  frequency 
according to stop deceleration and stop quadric deceleration till stops. 
1: Coast to stop 
When the stop command takes effect, the inverter stops the output immediately. The 
motor coasts to stop by its mechanical inertia.
