Honeywell VFD CORE

CHAPTER 12: DESCRIPTION OF PARAMETER SETTINGS
201 63-4528—04
• This parameter is used for the decel. time selection for momentary power loss.
• This function allows the VFD decelerates to stop after momentary power loss. When the momentary power loss occurs, this
function can be used for the motor to decelerate to 0 speed with deceleration stop method. When the power is on again, motor
will run again after dEb return time. (has applied on high-speed spindle)
Situation 1: Insufficient power supply due to momentary power-loss/unstable power (due to low voltage)/sudden heavy-load
Situation 2: Unexpected power off, such as momentary power loss.
2: 2nd decel. time
3: 3rd decel. time
4: 4th decel. time
5: Current decel. time
6: Auto decel. time
