The Kelly User's Manual names the KLS as "Kelly KSL Sensorless Motor Controller", and under 3.2 Connections: J2 Pin Definition, says "Hall phase (temporary unavailable)".
Can anyone confirm whether the Kelly KLS can be run with Hall Sensors?

KLS-8080I works with BLDC motors with hall sensors. KLS-8080IPS can work with BLDC motors with sine/cosine speed sensors.
