Error Handling
12 / 'Phase error'
Unrecoverable error / Motor is set in passive mode.
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.
- The servofilter (control loop) is unstable.
- The motor has been physically blocked.
- The motor has been running into a sudden mechanical colli-
sion.
- 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 43.
- Avoid that the motor during normal operation is meeting a me-
chanical collision or an extreme overload situation.
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
Bit 11 / 'IX_ERR'
12 / 'Overvoltage on bus'
Unrecoverable error / Motor is set in passive mode.
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.
- The internal brake resistor is not sufficient to handle the
amount of returned energy from the motor. Use an external re-
sistor or if already present lower the value of the resistor.
- The mains supply voltage is too high.
- 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 al-
ready present. See also Connecting an external power dump re-
sistor, page 68.
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
