Honeywell VFD CORE

CHAPTER 12: DESCRIPTION OF PARAMETER SETTINGS
63-4528—04 202
NOTE: For example, in textile machinery, you will hope that all the machines can be decelerated to stop to prevent bro-
ken stitching when power loss. In this case, the host controller will send a message to the VFD to use dEb func-
tion with deceleration time via EF.
• Pr.07-14 to Pr.07-17 is for heavy load to prevent OV or OC occurs.
• This parameter is used for the fan control.
• Setting 0: Fan will be ON as the drive’s power is turned ON.
• Setting 1: 1 minute after VFD stops, fan will be OFF
• Setting 2: VFD runs and fan will be ON. VFD stops and fan will be OFF.
• Setting 3: Fan run according to IGBT and capacitance temperature. Fan will be ON when preliminary capacitance temperature
is higher than 60
o
C. Fan will be OFF, when capacitance temperature is lower than 40
o
C.
• Setting 4: Fan is always OFF
