Error 8 Speed monitoring

Error: 8.1 (0801hex \| 2049dec) Description: Speed monitoring – motor mode

	Cause	Measure
	Speed controller operates at setting limit (mechanical overload or phase failure in supply system or motor).	– Increase delay time of speed monitoring. – Reduce the load. – Increase current limiting/torque limiting. – Reduce the acceleration. – Check the motor cable, motor, and line phases.
	Encoder not connected correctly.	Check the encoder connection.
	Encoder has incorrect direction of rotation.	Check the direction of rotation.

Error: 8.2 (0802hex \| 2050dec) Description: Speed monitoring – generator mode

	Cause	Measure
	Speed controller operates at setting limit (mechanical overload or phase failure in supply system or motor).	– Increase delay time of speed monitoring. – Reduce the load. – Increase current limiting/torque limiting. – Decrease deceleration. – Check the motor cable, motor, and line phases.
	Encoder not connected correctly.	Check the encoder connection.
	Encoder has incorrect direction of rotation.	Check the direction of rotation.

Error: 8.3 (0803hex \| 2051dec) Description: Maximum speed at motor shaft exceeded

	Cause	Measure
	The actual speed has exceeded the "Maximum speed at motor shaft" limit value. This limit value is set at startup matching the motor and gear unit.	Reduce the maximum speed.
	The setpoint is too high.	Reduce the setpoint
	The motor is driven by the load.	Check the project planning of the drive.
