Setup of the excess positional deviation protection
During the position control or full-closed control(Not supported), this function detects potential excessive
difference between the positional command and motor position and issues Err 24.0 Excess positional deviation
protection.
Excessive position deviation level can be set in Pr0.14" Position deviation excess setup ".
(See the control block diagram.)
Because the positional deviation during normal operation depends on the operating speed and gain setting, fill
the equation below based on your operating condition and input the resulting value to Pr 0.14.
Pr0.14" Position deviation excess setup "
＝
Ve / Kp * (1.2 - 2.0)
Ve
：
The maximum operating frequency of the encoder unit or external scale units [pulse/s]
Kp
：
Position loop gain [1/s]
Coefficients in parentheses are margins of protection to prevent frequent excessive position deviation.
Notes:
• When switching position loop gain Kp, select the smallest value for calculation.
• When switching from the velocity control to position control, position deviation correcting function is used,
which will increase calculation value and error. To cope with these problems, increase the margin.
5)
Setup of motor working range
During the position control or full-closed control(Not supported), this function detects the motor position which
exceeds the revolutions set to Pr 5.14 Motor working range setup, and issues Err 34.0 Software limit protection.
For details, refer to 6-2 Motor working range setup function.
