Cycle Analyst V3.1 User Manual
Rev 1.0

1 Introduction

Thank you for the purchase of a V3 Cycle Analyst device, Grin's latest model of
open standard display and control device for ebikes and other electric vehicles.
This document should help you get reasonably familiar with the basic setup and
operation of a CA3 as part of your vehicle system.

2 High Level Operation

The V3 Cycle Analyst is not like a typical ebike display interface that
communicates with one particular model of motor controller. Instead the CA3 is
designed as a more universal display and control unit. To achieve this
universality, it reads existing signals already present in most EV drives to sense
the power and speed of the vehicle, and then it regulates the motor power
through a common throttle signal.
This is an important concept to understand; the CA3 does not "communicate"
with your ebike in the same manner as proprietary display units. Rather it taps
into analog signals already present inside a motor controller and interprets them.
It then sends what it thinks is the most appropriate throttle voltage to your
controller for generating a target amount of power from the motor.
As far as your motor controller knows, the V3 Cycle Analyst is just a throttle
device. The CA3 can't change any internal controller settings, or make the
controller do anything more than what you could do via deft manipulation of a
normal throttle.
