Error Handling
14 / 'Overspeed'
Unrecoverable error / Motor is set in passive mode.
The actual velocity (speed) has been higher than allowed.
Please note that this message is only available in MAC400 and
MAC800.
- Velocity too high.
- Servofilter is not stiff enough and speed may overshoot during
start and/or stop or when sudden load changes happens.
This error is triggered at 4300 RPM (MAC400) and 3600 RPM
(MAC800).
- Make sure that the velocity setting is within specified range
(0-3000 RPM nominal).
- Make sure that the servo filter is set to stable setting in order
to avoid overshoots during acceleration or similar. See also
Servo filter adjustment, page 43.
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
Bit 13 / 'SPEED_ERR'
16 / 'SSI Read error'
Unrecoverable error / Motor is set in passive mode.
An external SSI encoder has been enabled but communication
with the encoder has failed.
- The encoder is not connected correctly.
- The format chosen is not compatible with the actual encoder.
- Improper cabling have been used.
- Use proper cabling between the motor and the external SSI en-
coder. A screened cable with twisted pair wires is recommend-
ed.
- Make sure that the right SSI format is selected.
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
