分解器
SERVOSTAR使用單（兩極）或多速度（多極）分解器
反饋以監(jiān)控電機軸位置。分解器可以被視為變壓器
其輸出對于任何給定的軸位置是唯一的（絕對位置反饋）。這個變壓器由正弦波參考信號驅動。兩個交流信號從分解器輸入正弦和余弦。
所有這三個正弦波信號都是低電平
易受噪聲影響。重要的是使用適當屏蔽的電纜，并使其遠離其他噪聲輻射設備和電纜。不建議以相同的方式運行反饋和電機電纜
管道Danaher Motion Kollmorgen測試了長達75英尺（22.9米）的電纜長度。沒有性能下降。但是，性能可能因電機和分解器而異
類型使用標準Danaher Motion Kollmorgen電纜及其低阻抗和Danaher Motion Kollmorgen GOLDLINE電機旋轉變壓器進行測試。請參閱當長電纜運行超過250英尺（76m） 是期望的。Danaher Motion Kollmorgen建議使用雙絞線屏蔽對進行反饋電纜。伺服星將電機速度計算為位置的導數（位置變化隨著時間的推移）。利用其專利技術，所有讀數都擴展到16位分辨率。對于驅動器將分解器輸入轉換為18位分辨率，從而提供平滑的電機速度控制。旋轉變壓器的數字分辨率（RDRES）為數字轉換器系統(tǒng)根據應用速度限制（VLIM）自動確定。
以下是SERVOSTAR分辨率能力的總結。SERVOSTAR以正交編碼器的形式向您提供電機位置輸出
信號消除了對附加位置反饋裝置的需要。產出如下：差分線路驅動器。有一個相關的直流公共輸出（C4：引腳3），可以連接將共模噪聲和電壓峰值降至最低，以保護設備。
由于控制器和驅動器之間通常存在電位差，建議連接（如果出現接地回路，斷開并重新測試）。

Resolver
The SERVOSTAR uses either single (two poles) or multi-speed (multiple poles) resolver
feedback to monitor the motor shaft position. A resolver can be thought of as a transformer
whose output is unique for any given shaft position (an absolute position feedback). The
transformer is driven with a sinewave reference signal. Two AC signals are returned from the
resolver into the Sine and Cosine inputs. All three of these sinewave signals are low-level and
susceptible to noise. It is important to use properly- shielded cable and to keep it away from other noise-radiating
devices and cables. It is not recommended to run the feedback and motor cables in the same
conduit. Danaher Motion Kollmorgen has tested cable lengths up to 75 ft. (22.9 m). without
degradation of performance. However, performance may vary, depending on motor and resolver
type. Tests were performed with standard Danaher Motion Kollmorgen cable and its lowimpedance and Danaher Motion Kollmorgen GOLDLINE motor resolver. Please consult the
factory for cable and resolver impedance specifications when long cable runs above 250 ft. (76
m) are desired. Danaher Motion Kollmorgen recommends twisted-shielded pair for feedback
cables. The SERVOSTAR calculates motor velocity as the derivative of position (change in position
over time). With its patented technique, all readings are extended to a resolution of 16-bit. For
velocity feedback calculations, the drive converts the resolver input to 18-bits of resolution,
giving smooth motor velocity control. The digital resolution (RDRES) of the Resolver-to-Digital
Converter system is determined automatically according to the application velocity limit (VLIM).
The following is a summary of the SERVOSTAR’s resolution capabilities The SERVOSTAR provides a motor position output to you in the form of quadrature encoder
signals eliminating the need for an additional position feedback device. The outputs are
differential line drivers. There is an associated DC common output (C4: pin 3) which can connect
to your port to keep common mode noise and voltage spikes minimized for device protection.
Because there are normally differences of potential between your controller and the drive,
connection is recommended (if ground loops occur, disconnect and retest).
