JVL A/S - User Manual - Integrated Servo Motors MAC050 - 4500
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, 402,
800, 1200, 1500, 3000 and MAC4500.
- Velocity too high.
- Servofilter is not stiff enough and speed may overshoot dur-
ing start and/or stop or when sudden load changes happens.
This error is triggered at 4300 RPM (MAC400 and MAC402)
and 3600 RPM (MAC800, MAC1200, MAC1500, MAC3000
and MAC4500).
- 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
- 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
encoder. A screened cable with twisted pair wires is recom-
mended.
- Make sure that the right SSI format is selected.
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
Bit 15 / 'SSI_ERR'
