No.
(Hex.)
Name Description
Default
(Range)
Z1-27
(85E0)
Brownout Voltage Level Sets the voltage level below which is a brownout condition. 98 V
(0 - 150 V)
■ Z1-28: Brownout Detection Time
No.
(Hex.)
Name Description
Default
(Range)
Z1-28
(85E1)
Brownout Detection Time Sets the length of time that the Bypass voltage must be less than the Brownout Voltage Level before
the Bypass will trigger a Brownout fault.

No.
(Hex.)
Name Description
Default
(Range)
Z1-32
(85E5)
Loss of Load Drive
Frequency
Sets the value to which the drive output frequency must be equal to or more than for the drive to
detect a loss of load.
