Hundreds place of F27.20 = 1: Delayed stop and trip protection
In case of wire disconnection, the 68# function terminal and protection output terminal
will act, the inverter will stop after running at the frequency of F27.24 for the time of F27.23
and then the protection will be enabled.
Hundreds place of F27.20 = 2: Material cutoff protection
In case of wire disconnection, the inverter will be in the protection status.
Hundreds place of F27.20 = 3:
Automatic reset of material cutoff protection
In case of wire disconnection, the inverter will be in the protection status and reset
automatically after the set delay time of F27.26.
Hundreds place of F27.20 = 4: Only output of material cutoff detection terminal (for
the straight wire drawing machine only)
In case of wire disconnection, the inverter will not be subject to trip protection, and only
the output terminal for material cutoff detection output will be valid.
Hundreds place of F27.20 =5: Automatic resetting of material cutoff detection
terminal (for the straight wire drawing machine only)
This is the same as the option 4. The terminal of material cutoff detection output is invalid
only when the swing rod returns to the normal range.
Thousands place of F27.20 = 0: Mode 0
Mode 0: When the output frequency is within the brake signal output frequency (F27.25)
from top to bottom, the brake will not work.
Thousands place of F27.20 = 1: Mode 1
Mode 1: When the output frequency is within the brake signal output frequency (F27.25)
from top to bottom, the brake will work.
Ten hundreds places of F27.20 = 0: no speed limit
There is no reverse speed limit.
Ten hundreds places of F27.20 = 1: reverse speed limit by F27.24
There is no reverse speed limit by F27.24.
