Error
code
Main Sub Display: “ Er 171 ”
17 1 Content: Encoder parameter initialization error
Cause Diagnosis Solution
Driver and motor
not matched
Verify driver and motor models.
Replace with matching driver and
motor
Error while getting
parameters from
encoder
1. Verify if encoder cable is standard.
2. Verify if encoder has no peeled
insulator, broken connection or
improper contact. Use standard encoder cable, verify
the connection of both sides of driver
and motor, change encoder cable if
necessary

Content: Excessive position deviation
Cause Diagnosis Solution
Improper position
deviation settings Verify if value of Pr_014 is too low Increase value of Pr_014
Position gain setting too
low Verify if values of Pr1.00 & Pr1.05 are
too low Increase values of Pr1.00 &
Pr1.05
Torque limit too low
Verify if values of Pr0.13 & Pr5.22 are
too low Increase values of Pr0.13 &
Pr5.22
Excessive external load
1. Verify if acceleration and
deceleration duration time
is too low.
2. Verify if rotational velocity is too
high
3. Verify if load is too large 1. Increase duration time for
acceleration and
deceleration
2. Decrease rotational
velocity
3. Decrease load

18 1
Content: Excessive velocity deviation
Cause Diagnosis Solution
Deviation between set
velocity and actual velocity is
too great
Verify if value of Pr6.02 is too
low
1. Increase value of Pr6.02;
2. Set Pr6.02 to 0, position error
detection off.
Acceleration and
deceleration duration time for
set velocity is too low
Verify if value of Pr3.12 and
Pr3.13 are too low
1. Increase value of Pr3.12, Pr3.13;
2. Adjust velocity gain to reduce
velocity lag error
Error

Main Sub
Display: “ Er 190 ”
19 0 Content: Vibration too strong
Cause Diagnosis Solution
Resonance
Mechanical stiffness is too
high, resonance occurs
Reduce mechanical stiffness or use
filter
Current loop gain too
large
Verify current loop gain value Reduce current loop gain
