n47 : Momentary Power Loss Ride-thru 0 = Disabled (Factory setting)
Protection 1 = Enabled – 2 sec. power loss
ride-thru
2 = Enabled – indefinite power loss
ride-thru, provided control
power is maintained
The setting of this parameter either enables or disables the ride-thru feature of the Drive. If
disabled, the unit will stop immediately whenever a power loss occurs. If enabled, the Drive will
continue to operate during a momentary power loss of up to 80%, but if the loss exceeds the
identified time period, the Drive will stop.
5.15 MOMENTARY POWER LOSS RIDE-THRU
n44 : Multi-function Analog Output Factory setting: 0
The monitor output provides a 0-10 Vdc signal
proportional to either output frequency or output current
between terminals AM & AC:
0 = 0-10 Vdc proportional
to output frequency
1 = 0-10 Vdc proportional
to output current
n45 : Analog Monitor Gain Factory Setting: 1.00
Range: 0.01 to 2.00
This constant is used to calibrate the meter connected to terminals AM & AC.
