4.7.2
Operation Sequence for Managing Parameters
Using SERVOPACK
The following describes the operation sequence for managing parameters using the non-vol-
atile memory of the SERVOPACK.
As described below, divide the operation into two steps.
Step 1: Saving parameters (during set-up)
Step 2: Ordinary operation sequence
* 1. If communication disconnects normally, the NOP command is sent. If communication does
not disconnect normally, the DISCONNECT command is sent for two or more communica-
tions cycles prior to connection, then the CONNECT command is sent.
* 2. Do not use PRM_WR.
