AUX. I/O CONFIG submenu
The
AUX. I/O CONFIG
menu group contains parameters associated with additional I/O modules that can be added with
specific options.

Auxiliary Digital
Output Function
Sets functionality of the auxiliary digital outputs.
O-C Cmd
Digital outputs provide programmable auxiliary limit switch outputs based on values set in the
“Calibrate Aux. DO Close” and “Calibrate Aux. DO Open” settings. This setting can only be used
with proportional control applications since it requires a percentage value based on using a
feedback potentiometer.
DO1 = Programmed Aux Close position
DO2 = Programmed Aux Open position
Lim SW
Digital outputs mirror the position limits of the switches connected to position switch header (P5).
DO1 = Close position limit
DO2 = Open position limit
Motor Out
Digital outputs mirror the motor outputs. When specified motor output is energized, the
corresponding digital output is activated.
DO1 = CW motor output
DO2 = CCW motor output

Auxiliary Digital
Input Function
Sets functionality of the auxiliary digital inputs.
Disable
Digital inputs are disabled.
Local Ctrl
Digital inputs are configured for local/remote inputs.
DI1 = Local close switch input. When DI1 terminals are powered, the TMC4 commands a 0.0%
signal and moves to programmed 0.0% position while DI3 detects local input. If operating
as on/off actuator, it will drive to the close position limit switch.
DI2 = Local open switch input. When DI2 terminals are powered, the TMC4 commands a
100.0% signal and moves to programmed 0.0% position while DI3 detects local input. If
operating as on/off actuator, it will drive to the open position limit switch.
DI3 = Local/remote switch input. When DI3 terminals are powered, the TMC4 goes into local
control mode and disables remote signals. It will only operate with signals input to DI1 and
DI2 terminals.

Auxiliary Analog
Output Function
Sets functionality of the auxiliary analog outputs.
Feedback
Provides auxiliary 0-20mA analog output independent of standard feedback signal based on
calibrated auxiliary output zero and span.
4mA
Provides constant 4mA analog output based on calibrated auxiliary output zero and span.
20mA
Provides constant 20mA analog output based on calibrated auxiliary output zero and span.

Calibrate Aux.
Analog Out Zero
Sets auxiliary analog output signal zero digital count value. When selected, use [PREVIOUS ▲] or [NEXT ▼] to
adjust feedback until desired value is measured. Note, this feedback will correspond to the programmed
“Calibrate Close Pos” position in the
POSITION CONFIG
menu. If command is set for reverse action, set this
value accordingly.
Value is scaled between 12 bit count of 0 and 4095 for the selected command type range.

Calibrate Aux.
Analog Out Span
Sets auxiliary analog output signal span digital count value. When selected, use [PREVIOUS ▲] or [NEXT ▼]
to adjust feedback until desired value is measured. Note, this feedback will correspond to the programmed
“Calibrate Open Pos” position in the
POSITION CONFIG
menu. If command is set for reverse action, set this
value accordingly.
Value is scaled between 12 bit count of 0 and 4095 for the selected command type range.
