Description
Some treadmill motor controllers
monitor the amount of current being delivered to the drive
motor. The software sets a maximum
amount of allowable drive motor current. This error
indicates that maximum drive motor
current has been reached.
Possible
Causes
1. The running belt and/or running
bed is badly worn.
2. A shorted or de-magnetized drive
motor is causing the high power demand.
Possible
Remedies
1. A clamp-on A.C. ammeter must be
used to determine the amount of A.C input current being
drawn by the treadmill under no load
and loaded conditions. The current readings can be
used to determine the condition of
the running belt and/or running bed. These same readings
should be taken on a similar unit
with a known good running belt and running bed. Those
readings can then be used as a
benchmark for future use. Replace the running belt and/or
running bed as required. Remember,
many running beds are double sided and the bed can
be flipped over rather than being
replaced.
2.
A known good drive motor must be substituted for the existing drive motor.
