CHV180 series frequency inverter special for elevator Appendix A
.122.
inverter start to run at zero speed, at the same time output running signal (Y1).
After T4, the inverter output brake closed signal (FC).
After T5, the inverter received brake feedback signal(FB), after affirming the
brake is open completely ,the inverter accelerate with emergency acceleration
(P1.22) reach to emergency speed (P1.21), and then run at a constant speed.
When elevator run to flat floor, the controller will cut off emergency command
(EMER), and the inverter begin to decelerate to stop with emergency
deceleration (P1.22), when decelerate to P8.13, after T6, the inverter output
brake open command (FC), and the controller cut off running command.
After T7, the inverter receives stop command, and then after the delay time of T8,
the inverter stop, and ouput releasing command (TC) to contactor and stop
signal (Y1) of elevator. At this time, one operation cycle is over.
