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.
t065 [DigIn TermBlk 05] = 12 “Aux Fault”
t081 [Relay Out 2 Sel] = 10 “Above Anlg V”

Use P047, P049 and P051
[Speed Referencex] to
select pulse input.
Jumper for DigIn
TermBlk 05 or 07 Sel
must be moved to Pulse
