IN OPERATION
In rotating tuning…
1.
If the motor rotates more than one tour, then
terminate operation by releasing UP and DOWN
buttons.
2.
In rotating tuning the motor rotates smoothly until
the nearest pole position.
3.
If it is currently staying just in its pole position, then it
firstly rotates for some degrees to get away from this
position and rotates again to find the pole position.
4.
If there is no rotation the system will terminate the
operation by giving an error message.
5.
Increase the value of the parameter C20-TUNING
CURRENT and repeat the tuning operation once
more.
6.
If the operation fails again, then increase C20 step by
step until the tuning operation will complete
successfully.
IN OPERATION
In stationary tuning…
Since there will be no rotation, brakes must be held
closed along the operation.
However, if the brakes are not adjusted well to hold
the machine fixed then the motor may rotate. In this
case tuning operation fails.
Therefore, the brakes must be checked before tuning
operation.
In stationary tuning the system will apply signal to
the motor to find pole position without any rotation.
Faults in Operation related to Tuning:
ENCODER ERROR:
This error is caused mainly due to the faulty or wrong
earth connections.
Check earth connections and wires.
MOTOR CONNECTION ERROR:
The device output stage does not sense three motor
phase windings.
The wires and connections between motor and the
device output should be checked.
ENABLE ERROR
This error arises if the safety line is cut by any reason
during the operation. Releasing RUN button may
cause this error.
TUNING ERROR
Any rotation of the motor in stationary tuning may
cause tuning error.
