Control Inputs (Pins 4, 5,6,7):
Input 1,2: Logic “1” (Open) = Not Active
      Logic “0” (0VDC) = Active
Direction: Logic “1” (Open) = CW
      Logic “0” (0VDC) = CCW
On/Off: Logic “1” (Open)  = On
   Logic “0” (0VDC)  = Off
Limit Inputs (Pins 8,9):
Limits: Logic “1” (Open) - Not Active, Motor Running
 Logic “0” (0VDC) - Active, Motor stops in given Direction
Note:
Open Inputs are inactive and internally pulled up to +5VDC for all 23MDS\

Inputs and Outputs
Inputs: All inputs are pulled up to 5VDC. A logic “0” activates inputs that are pulled up. An unconnected input will 
always remain inactive.
Direction: When this input is not active, the motor will be moving in the clockwise or “+” direction. When this 
input is active, the motor will move in the counterclockwise or “-“ direction. This input is not read when a software 
index command is given. To change direction while using the software, change the direction option there.  When...

Terminating Resistor
To eliminate noise on the transmission lines or  when using a 4000 ft. cable, a terminating resistor is suggested. 
If used, the termination resistor need only be added to the last (furthest from the RS485 converter box) 23MDSI 
Series motor/driver/controller on the network between pins A(-) and B(+) on the terminal block. The value of this 
resistor should be 120 ohms.
Axis Selection
Each 23MDSI Series motor/driver/controller is addressed using a programmable register allowing the...

Functions
Hard Limit Switches: When a hard limit switch is encountered, the pulses will stop. Hard limits are intended as 
either a home position or an emergency stop for your system.
Profile Inputs: These inputs are used to select and begin the specified motion profile. Only 1 input should be 
activated at a time.
Motion  Profiles:  The  indexer  will  accept  up  to  two  different  speed  or  motion  profiles.  Each  profile  has  it  own 
programmable Accel/Decel, Base speed, Max speed, Index...

SMPG-SMSI Software
The SMPG-SMSI software is a handy utility that supports Anaheim Automation’s programmable pulse generators 
and simple indexers.  Connecting your PC to the 23MDSI Series stepper motor/driver/controller, via RS485, the 
software can easily perform the following tasks:
 • Exercise and monitor the 23MDSI Series stepper motor/driver/controller
 • Directly communicate with the 23MDSI Series stepper motor/driver/contro\
