Micro-Positioning Control™
Micro-Positioning Control function can provide a reduced speed range operation for precise
positioning. Enabled by a Multi-Function Input, it multiplies the normal speed reference by the
Micro-Speed Gain. Two Micro-Speed Gains are available. Gain 1 (C2-01) and Gain 2 (C2-02). They
can be adjusted and enabled independently.

NOTE: If both Micro-Speed 1 and Micro-Speed 2 are enabled. Micro-Speed 1 always takes
higher priority over Micro-Speed 2.
