- IMC17 has an integrated NEMA 17 Step Motor, and comes in three different sizes:
  
  Part # Motor Body Length
  IMC17-S 2.69" (6.83cm)
  IMC17-M 2.92" (7.42cm)
  IMC17-L 3.24" (8.23cm)
  
  IMCE17 comes with a built-in Encoder*
  - 400 cycles per revolution (CPR)
  - 1600 pulses per revolution (PPR)
  - 2 channel quadrature TTL squarewave outputs
  *The IMCE17 has the optical encoder option. The encoder can be used to monitor speed, direction, and distance of travel. A controller measures the process' speed by simply timing how fast the encoder supplies pulses. It determines direction by monitoring which channel (A or B) rises first. It determines distance traveled by counting the number of pulses sent since movement began.

INPUT VOLTAGE: +12 to 40 VDC
DRIVE CURRENT(PER PHASE): 0.1 to 2.0 Amps Peak

List of Components:

IMC17 - Integrated Motor + Driver + Controller
DB9 cable
3-pin Connector
Serial Cable (not included)
PC
RS485 to RS232 Converter Card if using Serial Port to Communicate
Power Supply (+12 to 40 VDC)

Connection Specifications:

1. Find your Serial COM Port on your PC. Use a Male to Female Serial cable and connect one end of the cable to your PC. Take the other end of the cable and connect it to the Converter Card.

2. Use the DB-9 cable that is provided with the IMC17 to connect it to the motor. The 3-Pin, blue or white connector fits onto the Header of the Converter Card.

3. Finally, connect a +12 to 40 VDC Power supply to the Converter card. THe + and - labels are shown on the converter card.

4. Now you are ready to program your controller. Download the full Command List under Documents at the bottom of this page.

I cannot type anything in HyperTerminal:

Check to make sure that you have selected the correct COM Port. If you are using Windows 95, we suggest trying an operating system of Windows 98 or higher. Windows 95 has had problems with its HyperTerminal. Are you working on a Laptop? Sometimes there is a shift in the Ground on Laptop Serial Ports. Pin 5 on the Serial Port is Ground. Confirm that this is connected to a true ground.

Did you set your Properties settings correctly in HyperTerminal? Go to File Properties Settings ASCII Setup, and check the box 'Echo Typed Characters Locally'.

Is the LED closest to the red Address Dial flashing on the back of the IMC17 unit? A flashing LED indicates that the IMC17 is waiting for commands. The other steady LED indicates that Power is being supplied to it. If neither of these is on, then check to ensure that your Power Supply is functioning and connnected properly..

Check the Converter Card. Use a voltmeter to measure if Power is coming into the card correctly and if power is being supplied to the Controller properly.

I can type in HyperTerminal, but nothing happens:

Check the LED's. If neither is on, check the Power Supply. If one is steady, and the other LED is flashing, then the Power is being supplied correctly.

Is the IMC17 set to the correct Address? Check the Red Dial on the back of the unit. The white arrow should be pointing to the corresponding Address that you are sending commands to in HyperTerminal. Confirm that the arrow is not in between 2 Addresses.

Check the Converter Card. Use a voltmeter to measure if Power is coming into the card correctly and if power is being supplied to the Controller.

Assuming the Properties of HyperTerminal are set as described in the Manual (Getting Started), does HyperTerminal respond with a string of characters?
/0' indicates that the command is terminated
/0@ indicates that the command was received correctly
/0C indicates that the command is out of range
/0b indicates bad command

The IMC17 unit will accept commands, but Motor will stall in the middle of a command:

This means there is not enough current being supplied to the Motor. Use the m and l (lower case L) commands to change the current, or run the Motor at a Lower Speed (V command).
