4.7 Absolute Encoders4-494 Operationlimit value in the encoder, refer to 4.7.7 Multiturn Limit Disagreement Alarm (A.CC0).The standard specifications of the direct drive motor include a single-turn absolute encoder. Therefore, theencoder’s rotational serial data is always 0.The absolute value of the load side can be created with the motor shaft angle only even when constructing anabsolute position detecting system because the servomotor and the load can be directly connected.4.7.7 Multiturn Limit Disagreement Alarm (A.CC0)When the multiturn limit set value is changed with parameter Pn205, a multiturn limit disagreement alarm(A.CC0) will be displayed because the value differs from that of the encoder.If this alarm is displayed, perform the operation described below and change the multiturn limit value in theencoder to the value set in Pn205.This setting can also be performed with the adjustment command (ADJ). For details on the ADJ (Adjustment)command, refer to theΣ-V Series/DC Power InputΣ-V Series/Σ-V Series for Large-Capacity Models User’sManual MECHATROLINK-II Commands (Manual No.: SIEP S800000 54).Factory Setting (= 65535) Other Setting (≠65535)+32767-32768 Motor rotations0Rotationalserial dataReverseForward0Motor rotationsPn205 setting value ReverseForwardRotationalserial dataAlarmDisplay Alarm Name Alarm Output MeaningA.CC0 Multiturn Limit Disagreement OFF (H) Different multiturn limits have been set in theencoder and SERVOPACK.Step Display after Operation Keys Operation1 Press the Key to select the utility function. Andpress the or Key to select the Fn013.2Press the Key to view the execution display ofFn013.Note: If the display is not switched and “NO-OP” isdisplayed in the status display, the Write Pro-hibited Setting (Fn010 = 0001) is set. Checkthe setting and reset.3Press the Key to set the multiturn limit value.When the setting is completed, the status displayshows "DONE" for one second. The status displaythen returns to show "A.CC0" again.Note: If the Key is pressed instead of theKey, the multiturn limit value will not be reset.4 Press the Key to return to the display the proce-dure 1.5 To enable the change in the setting, turn the power OFF and ON again.A .
