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 ±0.15V
.
It is necessary to replace the controller
.
61 HIGH TEMPERATURE
This alarm occurs if the tempera-
ture of the controller base plate
overtakes 75 degrees.
Improve the cooling of the controller;
otherwise it is necessary to replace the
controller
.
65
MOTOR
TEMPERATURE
This alarm occurs only when DIA
MOTOR TEMP is on and the thermal
sensor inside the
motor measures a temperature
higher than 150 degrees. It
also occurs when trying to acquire
the motor resistance with a tempera-
ture in the motor higher than 150
degree (still with DIAG MOTOR
TEMP to ON).
Check that the thermal sensor in the
motor is working correctly
.
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-DC0 (not oversized). Other-
wise it is necessary to replace the con-
troller
.
71 POWER FAILURE #3
This alarm occurs when the cur- rent
in the phase V of the
motor is zero and the motor is com-
manded 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 cur- rent
in the phase U of the
motor is zero and the motor is com-
manded 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
.
73 POWER FAILURE #1
This alarm occurs when the cur- rent
in the phase W 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 W of the motor
.
Otherwise it is
necessary to replace the controller
.
83 BAD ENCODER SIGN
It occurs in applications with tog- gle
switches when the applied fre-
quency (FREQUENCY) and motor
sped (ENC SPEED)
have opposite sign.
Swap in between two encoder channels
(CNB#7 with CNB#8).
