Software coded for Power Assist Level 3 maximum, ignores display PAS setting
SS39ET series or similar Hall Effect IC Typical voltage response:
3
| Controller cable #6 (Diagram C) No connect. Controller cable #9 (Diagram C) No connect.
4
| Controller cable #2 (Diagram C) Harmony/NuVinci connection. Connects to voltage drop/regulator chip, ends in bullet connectors (not shown in Diagrams of this document) with adapter that ends in Blue Harmony plug. Slack hidden inside down tube.
5
| Controller cable #4 (Diagram C) Motor-hall sensor. Has in-line plug while sensor is contained within motor unit.
6
| Controller cable #3 (Diagram C) Torque Sensor. Has in-line plug while sensor is contained within motor unit.
7
| Controller is a 9-MOSFET design; industry typical 9-MOSFET will handle 25 Amps
8
| Controller microcontroller; STM32F0426T6

| Enviolo { NuVinci Optimized )
Grip Controller to Hub Interface connection is located above the Motor
assembly and not visible when motor is installed. Location has not been
verified.

Unlike the manual operation units. Automatic unit hubs can not be shifted
completely through the ratio range while stationary. Systems will wait for
pedaling or wheel movement. So downshift before coming to a full stop.
Appendix 1: Julet vs Higo
6 mm round connectors: HIGO (left side) and JULET (right side)
The HIGO male connector has a somewhat larger collar. with a larger
champfer in front to allow the female connector’s lip to use the champfer as a
ramp when inserting the connector It is also the reason why HIGO connectors
hold on tighter and are a touch more resistent to water entry.
TIP: Use some bowstring wax to lubricate the collar. making it easier
for the soft female lip to slide over it. This also allows for easier pulling
apart the connectors. at the same time making it ever more water resistant.
Here a cross-sectional view of the male connectors
