Swap the channels of the encoder (CNB#8 with CNB#7).
CAN Bus Code = 13
It occurs if a test to write and read one location in EEPROM fails.
The SW expects to read the written value. It occurs also when the
hour counter gives different values between the three redundant
locations in which it is recorded. It occurs also when the busy bit of
the EEPROM does not rise within 12 msec.
It is necessary to replace the controller.
CAN Bus Code = 244
The parameters to compensate for the gain of the current
amplifiers (ADJUSTMENT #03 and ADJUSTMENT #04) are
recorded in a not volatile memory (eeprom) with a redundant
handling. In fact every adjustment is recorded in three eeprom
locations. If the values in these three locations are different in
between this alarm occurs.
It is necessary to send the controller to Zapi to execute the
maximum current regulation.
CAN Bus Code = 225
This alarm occurs when the parameters to compensate for the
gain of the current amplifiers (ADJUSTMENT #03 and
ADJUSTMENT #04) have the default values (i.e. the maximum
current was not regulated).
It is necessary to send the controller to Zapi to perform the
maximum current regulation.
CAN Bus Code = 61
This alarm occurs if the temperature of the controller base plate
overtakes 78 degrees.
Improve the cooling of the controller; otherwise it is necessary to
replace the controller.
CAN Bus Code = 65
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
degrees (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.
