Multiturn Limit

This section describes how to set the multiturn limit from the MP3000 or SERVOPACK.
5.3.1

Check Items before Setup

Check the following items before setting the multiturn limit.
• Synchronous communications are established with the SERVOPACK (bit 0 in IW
• The Servomotor is OFF (Servo OFF) (bit 1 in IW
• An absolute encoder is used.
• The Pn002 = n.
Selections 2) is set to 0 (Use the encoder according to the encoder specifications).
• A multiturn limit disagreement alarm (A.CC0) has occurred on the SERVOPACK.*
*
A multiturn limit disagreement alarm (A.CC0) is displayed when the multiturn limit setting is changed with parame-
ter Pn205, because the value will differ from the value that is set for the encoder.
If there is a A.CC0 alarm (Multiturm Limit Mismatch) in the SERVOPACK, communications
