5. CONNECTORS A DB-9 female connector cable receives power and provides the control connections for the IMD17 Unit. Active signals are optically isolated. An open-collector drive is required to provide pulses for Step, levels for Direction and Disable/Enable.

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.
ALTERNATIVE STEP RESOLUTION CONNECTION It is possible to change the microstepping resolution by using the signal from the controller. Figure 5: Alternative Step Resolution Connection By sending a high signal to Pin 2 and/or Pin 3, the connection between these pins will be effectively closed with Pin 7. This will change the microstepping resolution. Please refer to the Table 3 for Step Resolution Settings. PLEASE NOTE: The microstepping resolution should not be changed on the fly, loss of step may occur.
INTERNAL SCHEMATIC The IMD17 has 3 optically isolated logic inputs. These inputs are isolated to minimize or eliminate electrical noise coupled onto the drive control signals. Each input is internally pulled-up to the level of the optocoupler supply and may be connected to sinking outputs on a controller or a PLC. These inputs are: Enable/Disable (Pin 4) Direction (Pin 5) Step Clock (Pin 9) Figure 6: Optically Isolated Inputs Within the Driver lies three 680 Ω Resistors and three Optocouplers.
8. TROUBLESHOOTING The Motor is in Holding Position, but does not rotate. This means that Power is being supplied to the driver and motor, so the power supply is OK. However, the signal generator might be causing the problem. Try changing the signal to TTL. If this doesn't help, is the external +5 VDC Power connected? Is Pin 4 (disable) touching Pin 7 (logic ground)? This will disable the driver from running. The Microstepping does not always change to the correct step resolution.
