Chapter 1 Overview • 12 USER MANUAL The DMC-13X 8 also provi des standard 64 ex tended I/O points. These TT L I/O points ar e software configurabl e in bank s of 8 point s, and can be brought out directl y on the IOM -1964 I/O module. Each axis on the controller has 2 encoders, the main enco der an d an auxiliary encoder.
USER MANUAL Chapter 1 Overview • 13 Encoder An encoder translates motion into electrical pulses which are fed back into the controller. T he DMC- 13X8 accepts feedback from either a rotary or linear e ncoder. Typical encoders provide two channels i n quadrature, known as CH A and CHB.

(Optional) Motor Off Jumpers The state of the motor upon power up may be selected with the placement of a hardware jumper on the controller.
Chapter 2 Getting Started • 20 USER MANUAL Example: Sinusoidal Commutation Configuration using a DMC-1348 BAXZ This comma n d caus es the contro ller to be re co nfigured as a DMC-132 8 con troller. The X and Z axe s are configured for sinusoidal commutation .
USER MANUAL Chapter 2 Getting Started • 21 To change the voltag e level of the AEN signal, note the state of the resistor pack on the ICM-1900. When Pin 1 i s on the 5V m ark, the out put volta ge is 0-5V. T o change t o 12 volts, pull the resistor pack and rotate it so that Pin 1 is on the 12 volt side.
Chapter 2 Getting Started • 22 USER MANUAL Each set of sensors m ust use inputs that are in consecutive order. The input lines are specified with the command, BI. For exampl e, if the Hall sensors of the Z axis are connected to in puts 6, 7 a nd 8, use the i nstruction: BI ,, 6 or BIZ = 6 Step 7a.
USER MANUAL Chapter 2 Getting Started • 23 For example, the following command will limit the output of the controller to 1 vo lt on the X axis: TL 1 <CR> Note: Once the correct polarity of the feedback loop has been determined, the torque limit should, in general, be increased to the defa ult value of 9.
