Bipolar
[Speed Reference1]
= 5 “0-10V Input” and
[10V Bipolar Enbl]
= 1 “Bi-Polar In”
Unipolar (Voltage)
[Speed Reference1]
= 5 “0-10V Input”
Unipolar (Current)
[Speed Reference1]
= 6 “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.
[DigIn TermBlk 05] = 12 “Aux Fault”
[Relay Out 2 Sel] = 10 “Above Anlg V”
[Relay Out 2 Level] = % Voltage Trip
Pulse Train Input
PowerFlex 523
t065 [DigIn TermBlk 05]
= 52
PowerFlex 525
t067 [DigIn TermBlk 07]
= 52
Use P047, P049 and P051
[Speed Referencex] to
select pulse input.
Jumper for DigIn TermBlk
05 or 07 Sel must be
moved to Pulse In.
