3-3-2 Automatic tuning error messages
If automatic tuning ends abnormally, the following message will appear. Investigate and confirm the
state following the error code.
– n
Automatic tuning step
No. Cause and remedy
n=1 The motor may not be connected correctly.
Check the connection.
The B00 and B01 parameters may not be set correctly.
Check the parameter setting.
n=2 The B00 and B01 parameters may not be set correctly.
Check the parameter setting.
n=3 The load and machine may not be separated.
Separate the load and machine.
Lengthen the acceleration time (A01-0).
Lengthen the deceleration time (A01-1).
If the motor vibrates, adjust the torque stabilizing gain (B18-2).
Normally, the d
efault value (1.00) is set, but increase the setting value in increments of approx.
0.05 according to the state of hunting. Please return to regulated value (1.00) of a set value
once, and reduce it by carving about 0.05 when the hunting phenomenon is not controlled
even in case of maximum value (4.00).
n=4 The load and machine may not be separated.
Separate the load and machine.
If the motor vibrates, increase the torque stabilizing gain (B18-2).
Normally, the d
efault value (1.00) is set, but increase the setting value in increments of approx.
0.05 according to the state of hunting. Please return to regulated value (1.00) of a set value
once, and reduce it by carving about 0.05 when the hunting phenomenon is not controlled
even in case of maximum value (4.00).
n=5 When the motor does not stop
Increase the acceleration/deceleration time (A01-0, A01-1).
When the motor does stop
The B00 and B01 parameters may not be set correctly.
Check the parameter setting.
n=6 The B00 and B01 parameters may not be set correctly.
Check the parameter setting.
n=8
Indicates that the output voltage did not stabilize for 1 second or more during magnetic pole
position estimation for the PM motor.
n=9 Indicates that the PM motor magnetic pole estimation did not end normally even after retrying
three times.
