Overview
This guide assumes that the motor has already been connected to power, and the Icon software has been set up and used successfully to connect to the motor. Visit the software landing page, quick-start guide, or installation and operation manual for assistance.
In this article, we will cover:
- Configuring the motor for analog/digital control via the Icon software
- Available settings for analog/digital I/O terminals
- Basic analog control wiring examples
- Advanced analog control examples
Configuring Motor for Analog/Digital Control
To use analog/digital control, the motor first needs to be connected to with the Icon software and the control mode set to “Analog/Digital”
- Provide power to the motor, and connect a device running Icon via ethernet cable (Modbus TCP)
- In Icon, select “CONNECT” at the top left. The motor should now be communicating with Icon
- Under “Parameter Settings” open the “Operation Type” dropdown
- For “Control Mode” select “Analog/Digital”
Step 2:
Steps 3 and 4:
Settings for Analog / Digital I/O Terminals
The functions available for analog/digital control can be assigned to various analog/digital I/O terminals. Please see Installation and Operation Manual for terminal electrical specs; improper use may damage motor.
- Observe default configuration in “Parameter Settings” tab, under “Operation Type” and “Terminal Settings”. Many applications do not require changes in this step.
- If changes are necessary, ensure that no single terminal is assigned to multiple functions, or you may experience control issues. Ensure that the “AI1 Type” is set to the correct setting for your control method: Voltage for 0-10V, Current for 4-20 mA.
-
Analog scaling may be configured under “Terminal Settings”, using the AI1 Min and Max (%) settings. This function requires that the AI1 function be set to speed. Analog scaling can be used to raise/lower the upper/lower bounds of the analog input. Example with 0-10V power supply:
- Changing the AI1 Min Setting (%) to 20% will set the motor to the user minimum speed at 2V.
- Changing the AI1 Max Setting (%) to 80% will set the motor to the user maximum speed at 8V.
-
The Analog/Digital Output terminals can be configured at the bottom of the “Terminal Settings” window.
- AO1 Function may be either Speed (outputs current motor speed based on AO1 type) or a constant 10V for self-contained potentiometer control. See Advanced Control Examples section
- DO1 and DO2 Function may be set to Active (motor on) or Fault (motor fault state)
The digital input terminals are only for use with +24V inputs. Assignable functions to DI terminals can be seen below. For a detailed look at motor parameters, see the motor parameters list.
Update with 4.1!
| Feature Name | Selections | Feature Description |
|---|---|---|
| Speed Input Source | Analog, Modbus | Determines input source for speed control |
| Start/Stop Input Source | DI1-4 | Determines input source for motor start and stop |
| Direction Input Source | DI1-4 | Determines input source for rotation direction |
| Clear Fault Input Source | DI1-4 | Determines input source for clearing motor fault |
| Motor Disable Input Source | DI1-4 | Determines input source for disabling motor |
Basic Wiring Setup
Ensure that power is disconnected from the motor before opening access panel.
Update with 4.1!
The simple analog control wiring method uses three wires:
-
+24V source to designated start/stop input source (DI1 by default)
- It is possible to use a jumper from the on-board +24V output to DI1. See note below.
- Two-wire 0-10V or 4-20 mA source to AI1 and GND
Jumper Method Notes:
- Using a jumper wire forces motor to user minimum speed if power to motor is supplied due to hardwired “ON” command. Speed control in desired speed range is still possible.
- The jumper wire may be replaced with a +24V signal wire to designated start/stop digital input terminal for external start/stop control.
Advanced Control Examples
Self-Contained Potentiometer Control
This method may be used to configure a motor for potentiometer control with no external control wiring required.
-
The AO1 terminal must be set to 10V (for potentiometer control)
- See “2. Settings for analog/digital I/O terminals”
- For an on/off switch: Connect +24V output to the DI1 (or other on/off command terminal) through desired switch type.
- For potentiometer control: Connect AO1 to AI1 through potentiometer.
