Introduction
www.ti.com
The DRV8846 customer EVM is a platform revolving around the DRV8846, a low voltage dual H-bridge
driver and highly configurable power stage. This device has been optimized to drive a single bipolar
stepper with up to 32 degrees of internally generated microstepping.
The EVM houses an MSP430 microcontroller and a USB interface chip. The USB chip allows for serial
communications from a PC computer where a Microsoft® Windows® application is used to schedule serial
commands. These commands can be used to control each of the device’s signals, and drive the stepper
motor by issuing the step commands at the desired rate.
The microcontroller firmware operates using internal index mode.
This user's guide details the operation of the EVM, as well as the hardware configurability of the
evaluation module.
2.1
Connectors
The DRV8846EVM offers access to VM (motor voltage) power rail via a terminal block (J1). A set of test
clips in parallel with the terminal block allows for the monitoring of the input power rail.
Apply VM according to datasheet-recommended parameters.
NOTE: VDD for the microcontroller is derived from the micro USB connector.

Operation of the EVM
Use the following steps to operate the EVM.
1. Install the drivers and GUI. Refer to Appendix A at the end of this document for instructions.
2. Connect the wires of the stepper motor to terminals AOUT1, AOUT2, BOUT1, and BOUT2.
3. Connect the VM power supply but do not apply power at this step.
4. Connect the USB between the PC and the EVM. Open the GUI by selecting the launcher.exe file. It
may take up to 15 seconds to establish connection.
(a) Once the USB connection is established, the Status LED will begin to blink.
5. Apply 12 V to the VM and GND connections.
6. Configure the current settings, step and decay modes, torque, and pwm off time as desired as shown
in the following image:
The current is calculated using the VREF slider, the Sense resistor value, the Torque setting, and the
Step mode setting using the formula.

Where StepModifier is 0.71 for full step and 1.0 for other STEP MODE settings
The 12-bit DAC channel 0 is connected to the DRV8846 analog input VREF. Changing the DAC digital
value from 0 to 4092 in steps of 4, changes the analog voltage at the VREF pin from 0 V to VINT V.
See Equation 2.

7. Wake and Enable the device for operation.
(a) After setting up the controls signals for the DRV8846, enabling the DRV8846 requires selecting
both the WAKE and ENABLE buttons. When the WAKE button or ENABLE button are selected, the
circle to the left of the button will toggle from red to green.
(b) The WAKE button, which controls the nSLEEP pin, is used to wake the DRV8846. The ENABLE
button, which controls the nENBL pin, is used to enable the DRV8846 outputs.
(c) A message which states that *Both WAKE and ENABLE must be Green to enable the motor control
buttons will be visible until both the WAKE and ENABLE buttons are activated. Once these two
buttons have been activated, the message disappears and the Start/Stop and Move Steps buttons
will be available.
(d) If the WAKE or ENABLE buttons are selected during motor operation, the motor is immediately
stopped and the STEP control signal from the microcontroller is reset.
8. The DRV8846 EVM is now awake and can be commanded to turn the motor. This can be done by
either selecting the Start/Stop Steps, Move # of Steps, or Reciprocate buttons.
The Start/Stop Steps button is used to run the motor indefinitely. The motor will accelerate to the target
speed and run until the Start/Stop Steps button is selected. When the Start/Stop Steps button is
selected, the red button will change to green, and the Move Steps and Reciprocate buttons will be
disabled.
The Move Steps button is used to allow movement of an exact number of steps. When the Move Steps
button is selected, the red button to the left of Move Steps will turn green, and the Start/Stop Steps and
Reciprocate buttons are disabled until the number of steps have completed.
The Reciprocate button is a special case of the Move Steps. When selected, the motor will advance
the specified number of steps in the direction initially set by the control inputs. After a short pause, the
motor will then advance the same number of steps in the opposite direction. This sequence is repeated
until the Reciprocate button is selected.
When the Reciprocate button is selected, the red button to the left of Reciprocate will turn green, and
the Start/Stop Steps and Move # of Steps buttons are disabled until the number of steps have
completed.

Motor Control Frame (Includes Start/Stop Steps and Move Steps)
The GUI has an area which offers access to a series of very useful stepper control algorithms. This area
allows for determining the best current settings during running at various speeds, and when holding torque
is applied.
Motor motion can only happen by using an acceleration profile which will be detailed later on. A detailed
explanation of each stepper control section follows.
This frame allows the configuration and running of the stepper with the direction as specified by the DIR
checkbox, with the current decay mode as specified under the Decay Mode checkbox and the
microstepping resolution as specified under the Step Mode drop down box.

Introduction
www.ti.com
The Motion Control frame gathers user information regarding stepping rate, or motor speed. An
acceleration profile is employed to start at a programmable speed and increase stepping rate until
reaching the programmable desired speed.
An internal 8-MHz timer is used to measure time and generate the steps on a timely manner. The GUI will
send the information to the microcontroller as PPS, and the microcontroller will transform it into the
respective clock cycles needed for the timer to generate accurate STEP pulse timing.
2.6.1
Start/Stop Steps
The acceleration profile is coded inside of the microcontroller to accept both the starting speed PPS and
target speed PPS as a clock cycle number. When the start steps command is issued (Starts/Steps button
is selected), the PWM timer generates steps at a rate specified by the start speed PPS parameter.
When accelerating or decelerating, PPS is adjusted every 32 ms, based on the integer value of PPSPS/32
ms. If a non-zero value of PPSPS is entered, a minimum value of 1 is used. The step rate is increased by
the calculated value until the target speed is reached.
The very same start steps command computes how frequent automatic speed updates are issued and a
second timer is used to change the speed according to the programmed acceleration rate profile.
Once the target speed (PPS) is reached, the acceleration profile ends and the motor stays running until
the stop stepper command is issued (Start/Stop Steps button is selected again). When the stepper is
commanded to stop, the controller does exactly as it did while accelerating, but in reverse to decelerate
until the stop speed PPS is reached, in which case the motor fully stops.
A second motor actuation is provided by the Move # of Steps and Reciprocate commands in which a
programmed number of steps are issued and then the motor stopped. The acceleration and deceleration
profiles work similarly as before, except when the deceleration starts and when the motor actually stops
are a function of the Steps to Stop and deceleration rate parameters.
This second motor actuation is adjusted automatically for rising edge or rising and falling edge settings in
the STEP MODE.
The following figure shows the acceleration profile and the role each parameter plays during speed
computation:
Target Speed
Steps to Stop
Acceleration Rate
Starting Speed
Stopping Speed
Number of Steps
2.6.2
Move Steps
If the user desires to move the stepper a certain number of steps, this can be accomplished by using the
move steps function. Parameters from the other frames are reused and its utilization is as explained
previously. Two new parameters have been added to properly control the limited number of steps
actuation.
Number of Steps: Number of steps the controller will issue.
Steps to Stop: The controller is continuously monitoring the step being issued and when the current step
is equal to the steps to stop parameter, a deceleration profile is issued. If Steps to Stop is larger than the
number of steps, then the motor stops abruptly and without undergoing a deceleration profile.
When a deceleration profile is issued, the controller decreases the speed until reaching the stop speed
value. If the number of steps parameter is met before the deceleration profile is complete, then the motor
stops at the current speed. If the stop speed is met before all the number of steps is issued, then the
motor rotates at the stop speed value until all the steps are executed.

Introduction
www.ti.com
Ideally, the system should be tuned to resemble the case in which the controller executes all the
commanded steps at a speed as close as possible to the stop speed. In the event this is not possible, due
to the particular parameters being chosen, stopping the motor at a speed very close to the stop speed is
often good enough to ensure good motion quality and application performance.
The following figure shows the three conditions possible when stopping and the action taken:
