ELECTRICAL INSTALLATION
Control Circuit Connections

Temperature Protection or PID Control with PT-100 or PTC Sensor
• Connect the sensor Positive wire to the AFM2 terminal. Place the AFM2 micro
switch in the down position.
• Connect the sensor Negative wire to the ACM terminal.
• Use a jumper wire to connect the AFM2 and AVI1 terminals. The AVI1 micro switch
should be in the up position.
• Any shield wire should be connected to Earth ground.
• For PT100, AVI1 Input Sel [IO-05] should be set to PT100 & AFM2 .
• If using PT100 for PID Feedback, Spare Sensor, or Aux Sensor, set the max value to 200 °C.
Speed Control using 0-10 VDC Potentiometer
• Connect the potentiometer Positive wire to the VFD +10V terminal.
• Connect the potentiometer Output wire to the AVI1, AVI2, or ACI terminal. The
AVI1 micro switch should be in the up position. If using the ACI terminal, the
ACI micro switch should be down.
• Connect the potentiometer Com wire to the ACM terminal (signal ground).
• Any shield wire should be connected to Earth ground.
• ACI Input Sel [IO–00] or AVI1 Input Sel [IO–05] should be set to 0-10V .
•
Auto Speed Ref [SET–07]
or
Hand Speed Ref [SET–09]
should be set to the chosen input.
Relay switching to control an external starter, contactor, or other system
• Connect the incoming power to the RC terminal.
• Wire the corresponding RA terminal to the external application.
• Set the relay control,
Relay RA1 [IO-47], Relay RA2 [IO-48], Relay RA3 [IO-49]
.
NOTE: Illustration example uses 120 V, relay 1, and a run light application.
External HOA switch
• Connect two MI terminals to DCM and the HOA switch.
• Wire a normally open run contact to DCM and FWD terminals.
• MI1 Define [IO-21] to MI8 Define [IO-28] of the two terminals should be set to 26_HOA-HAND ,
and
27_HOA-AUTO
.
• Put HOA Mode Source [SET_60] to Digital Input .
NOTE: Factory-installed drives use MI7 for Hand and MI8 for Auto.
