(15) Configurable motor over-temperature detection and protection with the
recommended thermistor KTY84-130/150 or KTY83-122.
(16) 3 hall position sensor inputs. Open collector, pull up provided. Sin/Cosin Speed
sensors inputs. Can not support Resolver sensor type.
(17)
Brake analog regen mode. This regen mode doesn't need brake switch to support
any more.
(18) Enhanced regen brake function. A novel ABS technique provides powerful and
smooth regen. The regen can happen at any speeds until zero speed.
(19) Cruise control. Only can be activated in forward direction.
(20) KHS-I/IPS can support Broadcast type CAN bus function. It is 250Kbps.By default,
KHS-I/IPS controller includes CAN bus function.
(21)
B
luetooth function. Required a small Bluetooth converter which needs to be
purchased in addition from our website. This small converter is only useful for KHS
controller.
(22) Can support three speed function on the latest version.
Caution!
The regen is not a safe function. Usually you may use the mechanical brake.
