Unipolar (Current)
P038 [Speed Reference]
= 3 “4-20mA Input”
Analog Input, PTC
For Drive Fault Wire the PTC and External Resistor (typically matched to the PTC Hot
Resistance) to I/O Terminals 12, 13, 14.
Wire R2/R3 Relay Output (SRC) to I/O Terminals 5 & 11.
A051 [Digital In1 Sel] = 3 “Aux Fault”
A055 [Relay Out Sel] = 10 “Above Anlg V”
A056 [Relay Out Level] = % Voltage Trip
