Error Handling
Error message ’Phase error’ (only MAC050 to 141)
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 permanent failure.
Please note that this message is only available in MAC050 to
MAC141.
Possible cause of this error
- The servofilter (control loop) is unstable.
- The motor has been physically blocked.
- The motor has been running into a sudden mechanical collision.
Solutions to avoid error
- Make sure that the servo filter is not set to an extreme unrealistic setting compared to the nature of the actual load. See
also Servo filter adjustment, page 50.
- 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’
Error message ’Overvoltage on bus’ (only MAC400 / 800)
Message no. / Message
12 / ’Overvoltage on bus’
Type / Motor action
Unrecoverable error / Motor is set in passive mode.
Error condition
The internal busvoltage has been higher than 450VDC which is
not allowed in order to prevent damages of the motor.
Please note that this message is only available in MAC400 and
MAC800.
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 error
can probably be avoided by connecting an external power
dump resistor or decrease the ohmic value if a resistor is already present. See also Connecting an external power dump resistor, page 86.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
