2.5 OPERATING MODES
The SPARK has three operating modes consisting of Brake Mode, Coast Mode, and Calibration Mode. It can also be
reset to the factory defaults.
The MODE button is used to switch between the three modes and to reset the SPARK to its factory defaults. It is located
near the power input terminals and is labeled as MODE in raised lettering on the SPARK housing. See Figure 2-5.
Figure 2-5 Mode Button
Use a straightened paper clip or other small implement to press the Mode Button.
The following sections describe each operating mode in detail.
2.5.1 BRAKE/ CO AST M ODE
When not driving the motor, the SPARK will short the motor terminals to dissipate electrical energy, effectively braking
the motor. Alternatively, the SPARK can be put in a Coast Mode which allows the motor to spin down at its own rate.
Press and release the MODE button to toggle between brake and coast mode. When in Brake Mode (default), the Status
LED will display a solid or blinking blue color. When in Coast Mode, the Status LED will display a solid or blinking yellow
color. See section 2.6 STATUS LED for more information.
This mode is saved in memory and persists through a power cycle.
