6. GETTING STARTED
In order to properly connect your new IMD17 Unit, first take a look at Figure 4, below.
Here’s a list of the parts needed to make the motor run:
• +12 to 24 Volt Power Supply
• Additional +5 Volt Power Supply
• Function Generator
1. Ensure that the IMD17 is not connected to the Main Power Supply until the
following procedures have been properly carried out.
2. Connect Pin 8 to the Positive Terminal of the +5 VDC Power Supply.
3. Connect the Negative Terminal of the +5 VDC Power Supply to the Negative
Terminal of the Signal Generator. This will be referred to as the Signal
Ground.
4. Connect Pin 1 and Pin 6 to the Positive and Negative Terminals of the Main
Power Supply, respectively.
5. Adjust the Frequency of the Signal Generator to achieve the desired
operating speed.

WARNING! DO NOT DISCONNECT THE DB-9 CABLE FROM THE IMD17 UNIT WHILE
POWER IS STILL BEING SUPPLIED. THIS MAY CAUSE DAMAGE TO THE INTERNAL
DRIVER BOARD.
WARNING! If you do not have a +5 VDC Power Source, use a Resistor in series to
limit the current of the opto isolators. See following page for Resistor values. If
the current exceeds 10 mA, the opto couplers cease to function.
