Introduction
The DRV8886 customer EVM is a platform revolving around the DRV8886, a medium-voltage dual Hbridge driver and highly-configurable power stage. This device has been optimized to drive a single bipolar
stepper with up to 16 degrees of internally generated microstepping.
The EVM houses an MSP430™ microcontroller and an USB interface chip. The USB chip allows for serial
communications from a PC computer where a Windows® application is used to schedule serial
commands. These commands can be used to control each of the device signals, and drive the stepper
motor by issuing the step commands at the desired rate.
The microcontroller firmware operates using an 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 DRV8886 EVM offers access to the VM (motor voltage) power rail through a terminal block (J1). A set
of test clips in parallel with the terminal block allows for the monitoring of the input power rail.
The user must apply the VM voltage according to recommended parameters listed in the data sheet.

StepModifier is 0.71 for full step and 1 for other STEP MODE settings
(1)
The number 1.232 is based on the maximum current allowed using the configuration. If VRREF = 0 V,
the maximum current is 1 A. The 12-bit DAC channel 1 is connected to the DRV8886 analog input
RREF through a 15-kΩ series resistor. The DAC voltage begins at 1.232 V (0%) and ends at 0 V
(100%).
Step 8. After setting up the control signals for the DRV8886, select both the WAKE and ENABLE
toggle buttons to enable the DRV8886. When toggled, the WAKE or ENABLE status toggles
between red and green.
The WAKE toggle button, which controls the nSLEEP pin, is used to wake the DRV8886. The ENABLE
toggle button, which controls the ENABLE pin, is used to enable the DRV8886 outputs.
A message stating Both WAKE and ENABLE must be green to enable the motor control buttons is
visible until both the WAKE and ENABLE toggle buttons are activated. When these two toggle buttons
have been activated, the message disappears and the Start/Stop Steps and Move # of Steps toggle
buttons are available.
If the WAKE or ENABLE toggle buttons are selected during motor operation, the motor is immediately
stopped and the STEP control signal from the microcontroller is reset.
Figure 4. Wake and Enable Toggle Buttons
Step 9.
The DRV8886 EVM is now awake and can be commanded to turn the motor. Turning the
motor occurs by either selecting the Start/Stop Steps, Move # of Steps, or Reciprocate toggle
button.
The Start/Stop Steps toggle button is used to run the motor indefinitely. The motor will accelerate to the
target speed and run until the Start/Stop Steps toggle button is selected. When the Start/Stop Steps toggle
button is selected, the red button changes to green, and the Move Steps and Reciprocate toggle buttons
are disabled.

The Move Steps toggle button is used to allow movement of an exact number of steps. When the Move
Steps toggle button is selected, the Move Steps toggle button turns green, and the Start/Stop Steps and
Reciprocate toggle buttons are disabled until the number of steps have completed.
The Reciprocate toggle button is a special case of the Move Steps option. When selected, the motor
advances the specified number of steps in the direction initially set by the control inputs. After a short
pause, the motor then advances the same number of steps in the opposite direction. This sequence is
repeated until the Reciprocate toggle button is selected.
When the Reciprocate toggle button is selected, the Reciprocate toggle button turns green, and the
Start/Stop Steps and Move # of Steps toggle buttons are disabled until the Reciprocate toggle button is
set to red and the number of steps have completed.
Figure 5. Reciprocate Toggle Button
As an extra precaution, the motor can be stopped by selecting either the WAKE or ENABLE toggle
buttons. When selected, the STEP commands are stopped and the motor control buttons are disabled. To
re-enable motor control, set the WAKE and ENABLE toggle buttons to green.

2.6
Motion 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.
Note: Both the WAKE and ENABLE toggle buttons must be green to enable the motor control buttons.
Figure 6. Motor Motion Profile
Motor motion can only happen by using an acceleration profile which is described in Section 2.6.1. A
detailed explanation of each stepper control section follows (see Section 2.6.1 and Section 2.6.2).
This frame allows the configuration and running of the stepper with the direction as specified by the DIR
toggle button, with the current decay mode as specified under the Decay Mode drop-down menu, and the
microstepping resolution as specified under the STEP MODE drop-down menu.
The Motion Control frame gathers user information regarding stepping rate or motor speed. An
acceleration profile is used to start at a programmable speed and increase the 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
sends the information to the microcontroller as pulse-per-second (PPS) signal, and the microcontroller
transforms it into the respective clock cycles required 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 signal
and target-speed PPS signal as a clock cycle number. When the START STEPS command is issued (the
Start/Stop Steps toggle button is selected), the PWM timer generates steps at a rate specified by the start
speed PPS parameter.
When accelerating or decelerating, the PPS signal is adjusted every 32 ms based on the integer value of
PPSPS / 32 ms. If a nonzero 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.
If the starting speed is greater than or equal to the target speed, the acceleration rate is set to 0. This
setting will prevent further speed changes until the motor is stopped, and new starting and target speeds
are entered. Texas Instruments recommends setting the starting speed to ½ the target speed to avoid this
scenario.
The very same START STEPS command computes how frequently automatic speed updates are issued
and a second timer is used to change the speed according to the programmed acceleration rate profile.
When the target speed PPS value is reached, the acceleration profile ends and the motor continues
running until the STOP STEPPER command is issued (the Start/Stop Steps toggle button is selected
again). When the stepper is commanded to stop, the controller performs the same actions as it did while
accelerating, but in reverse order to decelerate until the stop speed PPS value is reached, in which case
the motor fully stops.

Introduction
www.ti.com
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 is 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.
Figure 7 shows the acceleration profile and the role each parameter plays during speed computation.
Note: Both the WAKE and ENABLE toggle buttons must be green to enable the motor control buttons.
Figure 7. Acceleration Profile
2.6.2
Move Steps
To move the stepper a certain number of steps, use the move steps function to easily perform this action.
Parameters from the other frames are reused and their use is as previously explained. Two new
parameters have been added to properly control the limited number of steps actuation. These parameters
are described as follows:
Number of Steps — This parameter is the number of steps that 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 the value of the
Steps to Stop parameter 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 value of the
Stopping Speed parameter. If the # 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.
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
because of the particular parameters that were selected, stopping the motor at a speed very close to the
Stopping Speed parameter is often good enough to ensure good motion quality and application
performance.
Figure 8 shows the three conditions possible when stopping and the action taken.

EVM Use Restrictions and Warnings:
4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT
LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.
4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling
or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.
4.3 Safety-Related Warnings and Restrictions:
4.3.1
User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should contact a TI
field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
4.3.2
EVMs are intended solely for use by technically qualified, professional electronics experts who are familiar with the
dangers and application risks associated with handling electrical mechanical components, systems, and subsystems.
User assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees,
affiliates, contractors or designees. User assumes all responsibility and liability to ensure that any interfaces (electronic
and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely
limit accessible leakage currents to minimize the risk of electrical shock hazard. User assumes all responsibility and
liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or
designees.
4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal,
state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all
responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and
liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local
