Microstep Selection (SW1 Settings)
The select switches 2, 3 and 4 of the DIP switch, allow the user to select the number of microsteps per
step. The table below shows the standard resolution values along with the associated positions for the
select switches. The standard waveforms are sinusoidal. Microstep Selection Switches are located on the
side of the DPC40511.

Motor Selection
The DPC40511’s bipolar microstep driver is compatible with both bipolar and unipolar motor configurations,
(i.e. 8 and 4 lead motors, and 6 lead center tapped motors).
Step motors with low current ratings and high inductance will perform better at low speeds, providing
higher low-end torque. Motors with high current ratings and low inductance will perform better at higher
speeds, providing more high-end torque.
Since the DPC40511 is a constant current source, it is not...

Setting the Output Current
The output current on the DPC40511 is set by an onboard potentiometer. This potentiometer determines
the per phase peak output current of the driver. The relationship between the output current and the
potentiometer value is as follows:
Reducing Output Current
Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and
occurs approximately 20mSec after the last positive going edge of the step clock input. The...

4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potentiometer
value. Four Lead Motors are usually rated with their appropriate series current, as opposed to the 
Phase
Current
, which is the rating for 6 and 8 lead motors.
6 Lead Motors
When configuring a 6 lead motor in a half-coil configuration (connected from one end of the coil to the
center tap), multiply the specified per Phase (or unipolar) current rating by 1.4 to determine...

8 Lead Motors
Series Connection: When configuring the motor windings in series, use the per Phase (or unipolar)
current rating to determine the current setting potentiometer value.
Parallel Connection: When configuring the motor windings in parallel, multiply the per Phase (or unipolar)
current rating by 2.0 to determine the current setting potentiometer value.
Connecting the Step Motor
Phase 1 and Phase 3 of the step motor are connected to pins 1 and 2 on connector TB4. Phase 2 and...

Section 2: Controller Functions
Move Number of Steps: The move number of steps command causes the motion to start in the direction
last specified. This command will move the motor the number of steps given. (Range: 0 to 8388607)
Soft Limit Switches: These switches are used exclusively when homing to a datum point. If positioned
properly with the appropriate parameters, it causes the motor to ramp down to the base speed before
encountering the home limit switch. Limit Switch Inputs:...

Finish Move: When writing a program, the finish move command is used directly after a motion command.
With this command, the controller will see a busy signal until the move is complete before executing any
further commands. Unless the finish move command is used, the controller will keep on executing
commands, even though the controller is not ready to use it. This data will be ignored by the controller, so
the program will not work as expected.
Quit: The quit command, used within a...

Max Speed: The max speed is the top speed the user wants the motor to run at. This speed must always
be greater than the base speed. It is entered directly as the number of steps/second.
(Range: 77 to 15000) Acceleration/Deceleration: The acceleration and deceleration are by default the same value. This function
controls the time that the motor will take to move from base speed to max speed. The higher the value, the
slower the motor will accelerate. The same principal applies for the...

Section 3: SMC50WIN Software
The SMC50WIN software is a handy utility that supports Anaheim Automation’s line of PCL501 and
PCL511 step motor controllers.  Connecting your PC to the controller, via a serial cable, the SMC50WIN
software can easily perform the following tasks:
• Exercise and monitor the controller
• Write and edit stored programs for stand-alone operation
• Directly communicate with the controller
The software will automatically switch between the PCL501 and PCL511...

“The Unit is Connected” / “The Unit is NOT Connected”
On the right of the Toolbar, the user will find the communication status of the controller. If communication
is not established, please refer to the troubleshooting section.
