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(jī)軸位置。分解器可以被視為變壓器
其輸出對(duì)于任何給定的軸位置是唯一的（絕對(duì)位置反饋）。這個(gè)變壓器由正弦波參考信號(hào)驅(qū)動(dòng)。兩個(gè)交流信號(hào)從分解器輸入正弦和余弦。
所有這三個(gè)正弦波信號(hào)都是低電平
易受噪聲影響。重要的是使用適當(dāng)屏蔽的電纜，并使其遠(yuǎn)離其他噪聲輻射設(shè)備和電纜。不建議以相同的方式運(yùn)行反饋和電機(jī)電纜
管道Danaher Motion Kollmorgen測(cè)試了長(zhǎng)達(dá)75英尺（22.9米）的電纜長(zhǎng)度。沒(méi)有性能下降。但是，性能可能因電機(jī)和分解器而異
類型使用標(biāo)準(zhǔn)Danaher Motion Kollmorgen電纜及其低阻抗和Danaher Motion Kollmorgen GOLDLINE電機(jī)旋轉(zhuǎn)變壓器進(jìn)行測(cè)試。請(qǐng)參閱當(dāng)長(zhǎng)電纜運(yùn)行超過(guò)250英尺（76m） 是期望的。Danaher Motion Kollmorgen建議使用雙絞線屏蔽對(duì)進(jìn)行反饋電纜。伺服星將電機(jī)速度計(jì)算為位置的導(dǎo)數(shù)（位置變化隨著時(shí)間的推移）。利用其專利技術(shù)，所有讀數(shù)都擴(kuò)展到16位分辨率。對(duì)于驅(qū)動(dòng)器將分解器輸入轉(zhuǎn)換為18位分辨率，從而提供平滑的電機(jī)速度控制。旋轉(zhuǎn)變壓器的數(shù)字分辨率（RDRES）為數(shù)字轉(zhuǎn)換器系統(tǒng)根據(jù)應(yīng)用速度限制（VLIM）自動(dòng)確定。
以下是SERVOSTAR分辨率能力的總結(jié)。SERVOSTAR以正交編碼器的形式向您提供電機(jī)位置輸出
信號(hào)消除了對(duì)附加位置反饋裝置的需要。產(chǎn)出如下：差分線路驅(qū)動(dòng)器。有一個(gè)相關(guān)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(hù)設(shè)備。
由于控制器和驅(qū)動(dòng)器之間通常存在電位差，建議連接（如果出現(xiàn)接地回路，斷開(kāi)并重新測(cè)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).
