2.7 Error messages and error handling
2.7.8 Error message ’Temperature too high’ (only MAC400 to MAC4500)
2.7.9 Error message ’Low AC-voltage’ (only MAC400 to MAC4500)
Error message 11 do not exist since bits are used for other status purposes.
Message no. / Message
9 / ’Temperature too high’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition
The temperature has been higher than 84°C (183F) which is
not allowed.
Please note that this error is only available in MAC400,
MAC402, MAC800, MAC1200, MAC1500, MAC3000 and
MAC4500 since MAC050-141-A do not include a temperature
measurement circuit.
Possible cause of this error - The ambient temperature is higher than allowed - max is
+40°C/104°F.
- The motor is build into an environment where it can not dis-
sipate enough heat.
- The motor is not mounted on a proper mechanical structure
where heat can be dissipated.
Solutions to avoid error - Make precautions to decrease the surrounding ambient tem-
perature.
- Lower the speed and or load on the motor.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
Error bit / Firmware name Bit 8 / ’DEGC_ERR’
Message no. / Message
10 / ’Low AC-voltage’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition The mains supply is not connected or the mains voltage is too
low.
Please note that this message is only available in MAC400, 402,
800, 1200, 1500, 3000 and 4500 since MAC050-141-A/F do
not include AC supply.
Possible cause of this error - The mains supply is not connected correctly.
- The external fuse has blown.
Solutions to avoid error - Make sure that the external fuse is OK and that the mains
supply is connected correctly according to the chapter Power
Supply, page 89.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
