2.7 Error messages and error handling
2.7.10 Error message ’Phase error’ (only MAC050 to 141-A)
2.7.11 Error message ’Overvoltage on bus’ (only MAC400 to MAC4500)
Message no. / Message
12 / ’Phase error’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition
The motor phase current has been measured to be Out of
Range and the motor driver is shut down to prevent perma
-
nent failure.
Please note that this message is only available in MAC050 to
MAC141-A.
Possible cause of this error - The servo filter (control loop) is unstable.
- The motor has been physically blocked.
- The motor has been running into a sudden mechanical colli-
sion.
Solutions to avoid error - Make sure that the servo filter is not set to an extreme unre-
alistic setting compared to the nature of the actual load. See
also
Servo filter adjustment, page 49.
- Avoid that the motor during normal operation is meeting a
mechanical collision or an extreme overload situation.
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 11 / ’IX_ERR’
Message no. / Message
12 / ’Overvoltage on bus’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition The internal bus-voltage has been higher than 450VDC
(MAC402: 63V) which is not allowed in order to prevent dam
-
ages of the motor.
Please note that this message is only available in MAC400,
MAC402, MAC800, MAC1200, MAC1500, MAC3000 and
MAC4500.
Possible cause of this error - The internal brake resistor is not sufficient to handle the
amount of returned energy from the motor. Use an external
resistor or if already present lower the value of the resistor.
- The mains supply voltage is too high.
Solutions to avoid error - Make sure that the mains voltage is within specified voltage
range.
- If this error only happens during a motor movement the er-
ror can probably be avoided by connecting an external pow-
er dump resistor or decrease the ohmic value if a resistor is
already present. See also
Connecting an external power dump
resistor, page 104.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
