Error while getting
parameters from
encoder
Main Sub
Error
code
18
Cause
Improper position
deviation settings
Position gain setting too
low
Torque limit too low
Excessive external load
Main Sub
Error
code
18
Cause
Deviation between set
velocity and actual velocity is
too great
Acceleration and
deceleration duration time for
set velocity is too low
Main Sub
Error

Cause
Resonance
Current loop gain too
large
Error Main Sub
Display: "Er 171"
1 Content: Encoder parameter initialization error
Diagnosis
Verify driver and motor models.
1. Verify if encoder cable is standard.
2. Verify if encoder has no peeled
insulator, broken connection or
improper contact.
Display: "Er 180"
Content: Excessive position deviation
0
Diagnosis
Verify if value of Pr_014 is too low
Verify if values of Pr1.00 & Pr1.05 are
too low
Verify if values of Pr0.13 & Pr5.22 are
too low
1. Verify if acceleration and
deceleration
is too low.
2. Verify if rotational velocity is too
high
3. Verify if load is too large
Display: "Er 181"
1 Content: Excessive velocity deviation
Diagnosis
Verify if value of Pr6.02 is too
low
Verify if value of Pr3.12 and
Pr3.13 are too low
Display: "Er 190"
0 Content: Vibration too strong
Diagnosis
Mechanical stiffness is too
high, resonance occurs
Verify current loop gain value

Solution
Replace with matching driver and
motor
Use standard encoder cable, verify
the connection of both sides of driver
and motor, change encoder cable if
necessary
Solution
Increase value of Pr_014
Increase values of Pr1.00 &
Pr1.05
Increase values of Pr0.13 &
Pr5.22
1. Increase duration time for
duration time acceleration and
deceleration
2. Decrease rotational
velocity
3. Decrease load
Solution
1. Increase value of Pr6.02;
2. Set Pr6.02 to 0, position error
detection off.
1. Increase value of Pr3.12, Pr3.13;
2. Adjust velocity gain to reduce
velocity lag error
Solution
Reduce mechanical stiffness or use
filter
Reduce current loop gain
