5.2.2 Tuning-less Levels Setting (Fn200) Procedure
The following procedure is used for setting the tuning-less levels.
Setting tuning-less Levels is performed from the digital operator (optional), or SigmaWin+.
The operating procedure from the Digital Operator is described here.
For the basic operation of the digital operator, refer to Σ -V series User’s Manual, Operation of Digital Opera-
tor (SIEP S800000 55).
(1) Before Performing Tuning-less Function
Check the following settings before performing the tuning-less function, or otherwise “NO-OP” will be dis-
played during the tuning-less operation.
• The tuning-less function must be enabled. (Pn170.0 = 1)
• The write prohibited setting (Fn010) must not be set.
(2) Operating Procedure with Digital Operator
CAUTION
To ensure safety, perform tuning-less function in a state where the SERVOPACK can come to an emergency stop at
anytime.
