Control Circuit Connections
Terminal Identification
The control board is divided into 5 groups of terminals and connectors, plus a group of micro switches that
control individual terminal configurations.
•
Always insulate bare control or shield wires with shrink tubing or electrical tape to prevent short circuit.
•
The ideal length of stripped wire for control terminals is 5 mm.

Analog Inputs/Outputs
– These connections are used for transducers, sensors, and control systems
such as a BAS, BMS, or PLC. Use shielded cable with shield connected to the ground terminal. Ter
-
minals accept 26~16 AWG (0.13~1.3mm
2
) wires, and should be tightened to a torque of 1.73 lb-in (0.19
Nm).
•
ACI
is a 0-10 VDC or 4-20 mA input, adjustable by micro switch. Set
ACI Input Sel [IO–00]
to match the
switch setting. Default = 4-20 mA.
•
AVI1
is a 0-10 VDC or 4-20 mA input, adjustable by micro switch. Set
AVI1 Input Sel [IO–05]
to match
the switch setting. Default = 0-10 V.
•
AVI2
is a 0-10VDC input.
When an input source has been connected, select the appropriate terminal in either
Auto Speed Ref

,
Hand Speed Ref [SET

, or
PID F/B Source [SET
–

.
•
AFM1 & AFM2
are programmable, multi-function analog outputs. Refer to
AFMI Out Select [IO–59]
and
AFM2 Out Select [IO–61]
for options. Each output can be set by micro switch to 0-10V (min load 5k Ω at
2 mA) or 0/4-20 mA (max load 500 Ω).
•
+10V
terminal (with common ACM) provides a +10 VDC 50 mA power supply for input devices.
•
ACM
terminals are the common for analog inputs, outputs, and +10 VDC power supply. All ACM
terminals are connected internally.
IMPORTANT:
DCM and ACM terminals are isolated from each other and from the ground. Do not
connect these terminals to earth ground, which can cause electrical noise in control circuits and
unstable VFD operation.
