[4-20mA Loss Sel]
This parameter selects the drives reaction to a loss
of 4-20mA signal when the active [Freq Source] is
4-20mA.
Parameter Number

Factory Default
“Min/Alarm”
Units
Display Drive
“Min/Alarm” 0
Drive outputs [Minimum Freq] and
issues an alarm.
“Stop/Fault” 1
Drive stops and issues “Hertz Err
Fault”.
“Hold/Alarm” 2
Drive maintains last output freq and
issues an alarm.
“Max/Alarm” 3
Drive outputs [Maximum Freq] and
issues an alarm.
“Pre1/Alarm” 4
Drive outputs [Preset Freq 1] and
issues an alarm.
[Accel Time 2]
This value determines the time it will take the drive
to ramp from 0 Hz to [Maximum Freq]. The rate
determined by this value and [Maximum Freq] is
linear unless [S Curve Enable] is “Enabled.” It
applies to any increase in command frequency
unless [Accel Time 1] is selected.

[Decel Time 2]
This value determines the time it will take the drive
to ramp from [Maximum Freq] to 0 Hz. The rate
determined by this value and [Maximum Freq] is
linear unless [S Curve Enable] is “Enabled.” It
applies to any decrease in command frequency
unless [Decel Time 1] is selected.

[Stop Select 1]
This parameter selects the stopping mode when the
drive receives a valid stop command unless
[Stop Select 2] is selected.

Factory Default
“Coast”
Units
Display Drive
“Coast” 0
Causes the drive to turn off immediately.
“DC Brake” 1
Injects DC braking voltage into the motor.
Requires a value in both [DC Hold Time]
& [DC Hold Level].
“Ramp” 2
Drive decelerates to 0 Hz, then if [DC
Hold Time] & [DC Hold Level] are greater
than zero the holding brake is applied. If
the values equal zero, then the drive
turns off. Requires a value in [Decel Time
1] or [Decel Time 2].
“S Curve” 3
Drive causes S Curve Ramp to 0 Hz in
[Decel Time 1] or [Decel Time 2] x 2.
