雙增益（ANDG）輸入的額外好處。啟用時(shí)，系統(tǒng)使用兩個(gè)14位A/D
讀取用戶提供的模擬信號(hào)的輸入。一個(gè)輸入是±10V信號(hào)的直接讀數(shù)，而另一個(gè)包含2x增益項(xiàng)。當(dāng)輸入電壓于4V時(shí)，2x通道用于確定用戶的輸入電壓。這將分辨率擴(kuò)展到15位等效值。在4V以上
系統(tǒng)使用直接14位轉(zhuǎn)換。特殊的軟件算法用于最小化交叉失真并增加0.25V滯后。
模擬系統(tǒng)通常需要縮放和偏移偏置。SERVOSTAR CD Lite添加了模擬偏移

VDC輸入禁用或啟用電機(jī)的功率級(jí)輸出。必須向客戶提供信號(hào)，以使驅(qū)動(dòng)器啟用（結(jié)合其他參數(shù)；激活）并運(yùn)行。
不建議從邏輯電源（C5）上分接信號(hào)。此開關(guān)的切換也啟動(dòng)從故障狀態(tài)恢復(fù)的嘗試。
故障輸出繼電器（繼電器、繼電器模式）
SERVOSTAR CD Lite以繼電器（繼電器）的形式提供驅(qū)動(dòng)器就緒/驅(qū)動(dòng)器上升輸出
輸出繼電器（繼電器）輸出由SERVOSTAR CD Lite的微處理器控制。那里是一個(gè)軟件開關(guān)（RELAYMODE），用于將繼電器（繼電器）輸出配置為“驅(qū)動(dòng)器就緒”或“向上行駛”指示燈：如果RELAYMODE=0，則當(dāng)驅(qū)動(dòng)器無錯(cuò)誤并準(zhǔn)備運(yùn)行時(shí)，繼電器關(guān)閉。這是一個(gè)“驅(qū)動(dòng)器”“就緒”配置。
如果繼電器模式=1，則繼電器僅在驅(qū)動(dòng)器啟用時(shí)閉合。這是一個(gè)“開車上路”配置（活動(dòng)等于1）。
如果RELAYMODE=2不適用于CD-LITE。
如果繼電器模式=3，則繼電器在沒有故障時(shí)打開，當(dāng)驅(qū)動(dòng)器檢測(cè)到過錯(cuò)The input voltage from the differential receiver is applied to a precise 12-bit Analog-to-Digital (A/D) conversion system. The A/D conversion system is read by the microprocessor, 250μs for the velocity loop mode, and every 62.5μs for the torque (current) loop mode of operation. Encoder-based units have the additional benefit of a Dual Gain (ANDG) input. When enabled, the system uses two 14-bit A/D inputs to read the user-supplied analog signal. One input is a direct reading of the ± 10V signal, while the other incorporates a 2x gain term. When the input voltage is less than 4V, the 2x channel is used to determine the user’s input voltage. This extends the resolution to a 15-bit equivalent. Above 4V, the system uses the straight 14-bit conversion. Special software algorithms are used to minimize cross-over distortion and add 0.25 V hysterisis. Analog systems often require scaling and offset bias. The SERVOSTAR CD-Lite adds an analog offset (ANOFF1) variable to this reading, performs an analog deadband (ANDB) adjustment, and scales it through velocity loop input scaling (VSCALE), or torque loop input scaling (ISCALE) before passing the data to the selected control loop. The analog input (ANIN1) variable indicates the analog reading after the offset (ANOFF1) and the deadband (ANDB) adjustments, but before the loop scaling. The ANIN1 variable range is ± 22500 counts (or mV). The SERVOSTAR CD-Lite also has an automatic analog input zeroing function. Invoking the ANZERO command while the drive is enabled or disabled samples motor velocity over a 32 ms period and updates ANOFF1 accordingly to cancel out analog input offset. This command uses an internal offset mechanism that has finer resolution than ANOFF1 is capable of providing Remote Enable Input (REMOTE) The opto-isolated Remote Enable input (REMOTE) provides a hardware drive enable switch. This 12-24 VDC input disables or enables the power stage output to the motor. The signal must be customersupplied to get the drive to enable (in combination with other parameters; ACTIVE) and operate. Tapping the signal off the logic supply (C5) is not recommended. The toggling of this switch also initiates an attempt to recover from a fault condition. Fault Output Relay (RELAY, RELAYMODE) The SERVOSTAR CD-Lite provides a drive ready/drive up output in the form of a relay (RELAY) output. The relay (RELAY) output is controlled by the SERVOSTAR CD-Lite’s microprocessor. There is a software switch (RELAYMODE) that configures the relay (RELAY) output to act as a ‘Drive Ready’ or ‘Drive Up’ indicator: If RELAYMODE = 0, the relay is closed when the drive is error free and ready to run. This is a ‘Drive Ready’ configuration. If RELAYMODE = 1, the relay is closed only when the drive is enabled. This is a ‘Drive Up’ configuration (ACTIVE equals 1). If RELAYMODE = 2 is not avalible with CD-LITE. If RELAYMODE = 3, the relay is open when no faults are latch and closed when the drive detects a fault.
