19 1 Content: Excessive hybrid position deviation
Cause Diagnosis Solution
Driver UVW terminal output
single phasing or wiring error
Verify if UVW terminal wiring
connection is right
Make sure UVW terminals are
correctly connected to UVW of motor;
change motor power cable.
Motor rotor blocked
Look for mechanical
blockages
Check the machinery
Driver stiffness too low Verify if position loop and
velocity loop gain is too low Increase position loop and velocity
loop gain
Full closed loop position
deviation (
Deviation
between external encoder
feedback position and
motor feedback position
)
exceeds Pr0.33
Verify if Pr0.33 is set too low
Increase Pr0.33 set value accordingly
but please aware that doing so might
cause the position deviation to be
higher.
Error
code
Main Sub Display: “ Er 1A0 ”
1A 0 Content: Overspeed
Cause Diagnosis Solution
Motor velocity
exceeded first
speed limit
(Pr3.21)
1. Verify if velocity command is too high;
2. Verify if simulated velocity command voltage
is too high;
3. Verify if parameter value of Pr3.21 is too low;
4. Verify if input frequency and division
frequency coefficient of pulse train is proper;
5. Verify if encoder is wired correctly 1. Adjust velocity input
command; 2. Increase Pr3.21
value;
3. Adjust pulse train input
frequency and division
frequency coefficient;
4. Verify encoder wiring;
Error
code
Main Sub Display: “ Er 1A1 ”
1A 1 Content: Velocity out of control
Cause Diagnosis Solution
Motor velocity
out of control,
Excessive
velocity error Verify encoder phase sequence; Verify if UVW
cable is connected to the right terminal Reconnect UVW if wrongly
connected. If still remains
unsolved, please contact
technical support.
