controllers, bond B- of both controllers together
with heavy cable or copper strip.

current lower.

Internal reset
Reset caused by over current, high battery voltage
or low supply voltage. It is normal if occurs
occasionally.

Throttle isn’t zero
when try to
change direction
The controller won’t change drive direction if
throttle isn’t zero. Also it won’t change direction at
high speed. The controller will wait throttle and
speed close to zero before change direction.

Over voltage at
startup or
regeneration
The
controller
won’t
drive
motor
if
detect
overvoltage at power up. It will cut back regen
current or stop regen if detect overvoltage during
regen. You may set overvoltage threshold with GUI.
The max threshold is about 1.25 times of
controller rated voltage. I.e. you may set threshold
lower than 60V for 48V controller.
The LED flashes once at power on, then keeps on for normal operation. “1, 2”
means it flashed once, then flashes twice after 1 second. The time between two flashes
is 0.5 second. The pause time between one error code and another error code is 2
second.
