1: A motor deviation counter overflow error occurs when a long instruction pulse is entered.
Causes and solutions
(1) Generally, the gain setting is too large, and we can manually adjust the gain or adjust the gain automatically.
(2) The load is too heavy, and it is necessary to re-select the motor with a larger capacity, or to reduce the load. To avoid overload operation, it is recommended to install a reducer to increase the load capacity.
Second: the position control of the servo motor is not accurate
(1) Confirm whether the current value of the actual pulse sent by the controller is consistent with the one we need to set.
(2) Monitor whether the number of pulse instructions received by the servo drive is consistent with that sent by the controller, and check the control line cable if it is inconsistent.
(2) Generally, the gain setting is too large, and we can manually adjust the gain or adjust the gain automatically.
(3) The servo motor generates accumulated errors during operation, and it is recommended to carry out the origin search operation within the range where the error exceeds the allowable range.
(4) The accuracy of the purchased servo motor itself is not high or the transmission mechanism is abnormal.
Three: servo motor position control operation, report overspeed fault handling method
(1) Check whether the servo power line and coding line are installed correctly, and whether the surface is damaged
(2) The gear ratio of the electronics is set too large
(3) The gain setting is too big, we can adjust the gain manually or adjust the gain automatically.
