Unit Selection
In order to select a unit the @ command followed by 0 (address of the unit) must be sent.
NOTE: There should be no spaces between the @ and address select.
How to select the unit:
@0  (Unit is selected)
@1  (Unit is selected)
@29  (Unit 29 is selected)
How to get a response from the unit:

EA - Encoder Autocorrect Enabled
Format:   EA[0 or 1]
Description:  This command will either enable or disable the encoder auto correct func-
tion.  To enable the function use a 1, to disable the function use a 0.  When this function is 
enabled, the relative register is used to calculate the encoder position, therefore before the 
next move is made, the relative register needs to be set.  This command is used in con-
junction with the encoder delay “ED”, encoder ratio “EM”, encoder retries “ER” and encoder 
window “EW” commands.

remove the ringing that might be associated with the mechanics of the system.  This com-
mand is used in conjunction with the encoder auto correct “EA” command.
Range:    0 - 65535
EM - Encoder Motor Ratio
Format:   EM[value]
Description:  This represents the ratio for the number of encoder pulses to one motor step.  
An example is for a 1000 line quadrature encoder and a 400 step/revolution motor, the mo-
tor ratio is (1000 * 4)/400 = 10.  This command is used in conjunction with the encoder auto 
correct EA command.
Range:    1 - 255
ER - Encoder Retries
Format:   ER[value]
Description:  This is the number of times the DPY50601 controller will try to auto correct 
the motor before an error occurs.  This command is used in conjunction with the encoder 
auto correct EA command.  When the auto correct error, Output 8 will be triggered.

the B (base speed), M (max speed), and A (acceleration/deceleration) 
commands.
H1:  In type 1 homing, the DPY50601 will send clocks until a soft limit is 
reached, then ramp down to base speed, change directions and run at 
base speed unit the release of the home limit input.  The ramp profi le 
is specifi ed by the B(base speed), M(max speed), and A(acceleration/
deceleration) commands.
I - Read Inputs
Format 1:  IR
Description:  This command returns the binary value of the inputs to the PC.  Since the 
inputs are pulled up internally (except input 1), they will return a high when they are open.  
For example; if all inputs are active (grounded), the command will return a 0.  If all inputs are 
inactive (open), the command will return a 63.  Input 1 is the LSB and input 6 is the MSB.
Format 2:  I[input]
Description:  This command returns the value of the selected input to the PC.  If the input 
is open or high it will return a 1.  If the input is grounded or low it will return a 0.
Range:    0 - 6
J - Fast Jog Speed

Format 1:  M[value]
Description:  This command sets the maximum (running) speed for motion.  This value 
must be set before motion begins, and be greater than the base speed.
Range:    1 - 50000
Format 2:  M
Description: This command uses the voltage on input 1 to calculate and set the max speed.  
The analog speed must be enabled for this command to work.  This command is used in 
conjunction with the analog speed “;”, the analog speed lower limit “[“, and the analog speed 
lower limit “]” commands.  This value must be set before motion begins.
N - Number of Steps
Format 1:  N[value]
Description:  This command sets the number of clocks for the DPY50601 to send out fol-
lowing a G command.  It is also used to set the registration index during and index on the 
fl y move.  Motion is not activated by this command; it only sets the index register.
Range:    0 - 8388607
Format 2:  N
Description:  This command reads the thumbwheel switches to set the number of clocks 
for the DPY50601 to send out following a G command.  For this command to work SW2 
must be in the TWS position, and the thumbwheel enable bit must be enabled.  Motion is 
not activated by this command, it only sets the index register.  This command is used in 
conjunction with the thumbwheel enabled “/” command.
O - Set Outputs
Format 1:  OR[value]
Description: This command sets the output register according to the binary value entered. 
Output 1 is the LSB and output 8 is the MSB.

the register.  (N = P - Z)
Range:    -8388607 to +8388607
Format 2:  P
Description:  This command uses the voltage on input 1 to calculate and set the number 
of clocks for the DPY50601 to send out following a G command.  The analog position must 
be enabled for this command to work.  Motion is not activated by this command, it only sets 
the register (N = P - Z).  This command is used in conjunction with the analog position “:”, 
the analog position lower limit “{“, and the analog position lower limit “}” commands.
S - Go Slew
Format:   S
Description:  This command will send clocks out to the DPY50601.  The only commands 
that can stop the clocks are; “.” (stop motion) or “,” (soft limit).  Motion can also be stopped 
by using the limit switch inputs.  The ramp profi le is specifi ed by the B (base speed), M (max 
speed), and A (acceleration/deceleration) commands.
T - Motor Current Enabled
Format 1:  T[0 or 1]
Description:  This command will control the On/Off output, which is designed to connect to 
the on/off input of Anaheim Automation’s step motor drivers.  To energize and allow current 
to fl ow through the coil of the motor, set the value to 1.  To de-energize and turn the current 
off to the motor, set the value to 0.  This is a dedicated output, and not controlled with the
