53 STBY I HIGH
This alarm occurs two ways:
1) In the initial rest state after key
on, if the outputs of the current
amplifiers are not comprised in the
window 2.2 to 2.8 Vdc.
2) After the initial diagnosis this
alarm occurs when the outputs of
the current amplifiers at rest have a
drift larger than ±0.15 V.
It is necessary to replace
the controller.
61 HIGH TEMPERATURE
T h i s a l a r m o c c u r s i f t h e
temperature of the controller base
plate overtakes 75 degrees.
Improve the cooling of the
controller; otherwise it is
necessary to replace the
controller.
65 MOTOR TEMPERAT.
This alarm occurs only when DIAG
MOTOR TEMP is on and the
thermal sensor inside the motor
measures a temperature higher
than 150 degrees. It occurs also
when trying to acquire the motor
resistance with a temperature in the
motor higher than 150 degree
(still with DIAG MOTOR TEMP to
ON).
Check the thermal sensor in
the motor is right working. If
it is, improve the cooling of
the motor.
70 HIGH CURRENT
This alarm occurs if the circuit to
limit via hardware the current in the
motor is either always active at key-
on or repeatedly active when the
motor is turning.
Check the motor is suited to
work with the eps-ac0 (not
oversized). Otherwise it is
necessary to replace the
controller.
71 POWER FAILURE #3
This alarm occurs when the current
in the phase V of the motor is zero
and the motor is commanded for
moving.
Check the power fuse is OK.
Check the battery positive
arrives to the controller.
Check the continuity of
the wire in the phase V of
the motor. Otherwise it is
necessary to replace the
controller.
72 POWER FAILURE #2
This alarm occurs when the current
in the phase U of the motor is zero
and the motor is commanded for
moving.
Check the power fuse is OK.
Check the battery positive
arrives to the controller.
Check the continuity of
the wire in the phase U of
the motor. Otherwise it is
necessary to replace the
controller.
