JVL A/S - User Manual - Integrated Servo Motors MAC050 - 4500
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 perma-
nent failure.
Please note that this message is only available in MAC050 to
MAC141-A.
- The servo filter (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
- Avoid that the motor during normal operation is meeting a
mechanical 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 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.
- 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.
- 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
resistor, page 104.
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
