When using linear motors, the maximum encoder frequency is 12.8MHz. The maximum setting of parameter Pn281 (Encoder Resolution) is dependent upon parameter Pn280 (Linear Scale Pitch) and Pn384 (Peak Motor Speed.) Attached to this document (.JPG file) is a table showing the maximum setting for Pn281 for specific Pn280 and Pn384 settings.
Monitor Un010 can also be used to monitor the following:
A) The maximum value of Pn281 (Encoder Resolution) for a given Pn280 (Linear Scale Pitch) and Pn384 (Peak Motor Speed) (default monitor.)
B) The maximum value of Pn384 (Peak Motor Speed) for a given Pn280 (Linear Scale Pitch) and Pn281 (Encoder Resolution.) Set Pn080.3=1 to enable this monitor.
