LCD Display

Range Yes

No (Default)

Description Selecting yes will allow the drive to function on single phase input power. If this parameter is set to No,

the drive will fault on “Phase Loss” when single phase power is applied. Consult factory before using a

drive on single phase power.

See page 34 for more information on single phase.

Description This parameter congures what action is taken, if any, when the drive loses the reference speed input

signal (Vin1, Cin, Vin2). The input signal needs to be congured as a 4-20mA input. A Fault 22, Ref Loss

will result when the signal is at or below the trip level of 3.0 mA. When congured to a 0 - 20mA or a

0 - 10V input, the monitoring/fault is not active. Also, if the input signal (Vin1, Cin, Vin2) is congured

for broken wire detection and the input is disconnected, a fault 23, broken Wire will result.

Displayed Name Action taken when signal is lost

Retain Spd The last known reference speed will remain in effect.

Preset Lvl The drive will ramp to the frequency set by parameter AFN 30 (Lost Ref Freq)

Fault (Default) A fault is generated and the drive stops.
