Drive Fault / Motor Drive Failure (Sector)

Drive Fault / Motor Drive Failure (Sector)

Possible Causes
• Loose drive connections
• Faulty electric motor
• The H-bridge on the controller is damaged, possibly a blown FET
• The electric motor is faulty or has been disconnected

Solutions
• Check drive connections (motor and battery) and secure if
necessary
• Replace faulty electric motor
• Check that the MOTOR, FUSE and DRIVE cells are all
ticked in the information screen.
An ‘x’, question mark or anything other than a tick indicates
a fault. In the case of a damaged H-bridge, the display will
typically indicate the part of the bridge that is damaged
(i.e. Q1Q3, Q2Q4, etc.)
• In the event of a Drive Fault, the controller must be
repaired by an authorised workshop
• Ensure that the electric motor terminals are connected to
the controller
• Check the function of the electric motor by referring to the
information screen described above, or test the motor by
connecting the motor terminals straight onto the battery
• If the motor does not run, the commutator is most
probably faulty
