The value is invalid.#3 (PLS): The number of position feedback pulses per motor revolution, specified inparameter No. 2024, is zero or less. The value is invalid.#4 (DIR): The wrong direction of rotation for the motor is specified in parameter No.2022 (the value is other than 111 or –111).#6 (AXS): In parameter No. 1023 (servo axis number), a value that falls outside therange of 1 to the number of controlled axes is specified. (For example, 4 isspecified instead of 3.) Alternatively, the values specified in theparameter are not consecutive.56
