Input/Output Connection Example
Potentiometer
1-10k Ohm Pot.
Recommended
(2 Watt minimum) P038 [Speed Reference] = 2 “0-10V Input”
Analog Input
0 to +10V, 100k ohm
impedance
4-20 mA, 250 ohm
impedance Bipolar
P038 [Speed Reference]
= 2 “0-10V Input” and
A123 [10V Bipolar Enbl]
= 1 “Bi-Polar In”
Unipolar (Voltage)
P038 [Speed Reference]
= 2 “0-10V Input”
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
