SPARK Flex Specifications

The following tables provide the operating and mechanical specifications for the SPARK Flex Motor Controller.

DO NOT exceed the maximum electrical specifications. Doing so will cause permanent damage to the SPARK Flex and will void the warranty.

Neutral corresponds to zero output voltage (0 V) and is either braking or coasting depending on the current idle behavior mode.

††

If a valid pulse isn't received within the timeout period, the SPARK Flex will disable its output.

†††

Input deadband is added to each side of the neutral pulse width. Within the deadband, output state is neutral. The deadband value is configurable using the REV Hardware Client or through the CAN interface.
