Absolute type
MPRZ Series (Supports Various Sizes)
Company：NIDEC MACHINE TOOL CORPORATION
Features
Application
Highly suitable for absolute feedback detector of direct motor and precise rotation table.
This Scale is applied to the position detection of Rotary table with DD motor or reduction mechanism. Especially most suitable for DD motor.
Moreover, suitable for Machining center with the turning function, since especially ultra high-speed detection is possible.

※1：Positioning error shows peak-to-peak within 1 rotation. Interpolation error (error within 1 pitch of Scale) is not included.
※2：Wiring is not included in weight.
※3：The number of poles is the number of patterns on the Scale.
※4：Connection of YASKAWA ΣV & Σ7 is only applicable in the case of DD motor.
