BENTLY 184684-01位移監(jiān)測(cè)器
SERVOSTAR CD-Lite的微處理器不斷監(jiān)控許多不同的狀態(tài)組件。通常，所有故障條件都被鎖定，因此您可以輕松確定問題當(dāng)檢測(cè)到故障時(shí)，將其記錄在狀態(tài)顯示中指示的內(nèi)部錯(cuò)誤日志中，通過串行端口發(fā)出，在大多數(shù)情況下會(huì)導(dǎo)致驅(qū)動(dòng)器禁用。許多故障可以重置通過切換硬件遠(yuǎn)程啟用（遠(yuǎn)程輸入）。以下是更常見的：驅(qū)動(dòng)器在裝置硬件和操作系統(tǒng)中檢測(cè)到的故障。
電機(jī)過熱：監(jiān)控電機(jī)外部恒溫器輸入是否開路條件用戶可以定義（使用THERMODE）在此故障條件下發(fā)生的情況。最壞的當(dāng)狀態(tài)顯示中出現(xiàn)“H”且故障繼電器觸點(diǎn)（繼電器）斷開。
驅(qū)動(dòng)器超溫：監(jiān)控內(nèi)部散熱器溫度是否處于不安全狀態(tài)。這條件導(dǎo)致顯示“t”并禁用驅(qū)動(dòng)器。驅(qū)動(dòng)器最終將冷卻到：允許重置此條件。
RMS過電流（回流）：回流檢測(cè)系統(tǒng)可“箝位”可用輸出現(xiàn)在的這不是真正的故障狀況，但由于命令的原因，可能會(huì)導(dǎo)致不期望的性能電流被限制在低于實(shí)現(xiàn)期望性能所需的電流。這種情況是狀態(tài)顯示中以閃爍的“F”表示，可通過監(jiān)控折疊開關(guān)檢測(cè)變量
總線過電壓：過電壓條件關(guān)閉驅(qū)動(dòng)器，并在狀態(tài)顯示。該故障主要發(fā)生在再生操作期間，此時(shí)總線升高到較高值而不是由電源產(chǎn)生的。
總線欠壓
欠壓狀態(tài)會(huì)關(guān)閉驅(qū)動(dòng)器并在狀態(tài)中顯示“u”陳列該故障通常發(fā)生在進(jìn)線電壓下降或電源。功率級(jí)故障（過電流）：硬件電路監(jiān)控負(fù)載短路、晶體管故障，以及瞬時(shí)過電流。通常，切換遠(yuǎn)程啟用不能重置功率級(jí)故障。電源必須循環(huán)。狀態(tài)顯示中閃爍的“P”表示此情況。
低壓電源故障：超出±12 VDC模擬電源的公差值將導(dǎo)致將顯示“A”并禁用驅(qū)動(dòng)器。
超速故障：軟件持續(xù)監(jiān)控實(shí)際（反饋）速度。如果電機(jī)速度超過VOSPD限制時(shí)，顯示“J”并禁用驅(qū)動(dòng)器。這通常發(fā)生在：是一個(gè)調(diào)整不當(dāng)?shù)南到y(tǒng)，負(fù)載超過其指令速度。
無補(bǔ)償器：如果伺服星無法設(shè)計(jì)補(bǔ)償器（在RSTVAR命令之后，CLEEPROM，或電機(jī)或驅(qū)動(dòng)參數(shù)的任何變化），顯示閃爍的減號(hào)（-）并使驅(qū)動(dòng)器禁用。此顯示通常表示驅(qū)動(dòng)器沒有補(bǔ)償文件已加載。

The SERVOSTAR CD-Lite’s microprocessor is constantly monitoring the status of many different
components. In general, all fault conditions are latched so you can readily determine the source of the
problem. When a fault is detected, it is logged in the internal error log, indicated in the status display,
enunciated over the serial port, and in most conditions causes a drive disable. Many faults can be reset
by toggling the hardware remote enable (REMOTE input). The following is a list of the more frequent
faults the drive detects in the unit hardware and operating system.
Motor OverTemperature: The Motor’s External Thermostat input is monitored for an open circuit
condition. The user can define (using THERMODE) what happens under this fault condition. The worst
case event is a power stage disable when an ‘H’ appears in the status display, and the fault relay contacts
(RELAY) are open.
Drive OverTemperature: The internal heatsink temperature is monitored for an unsafe condition. This
condition causes a ‘t’ to be displayed and disables the drive. The drive will eventually cool enough to
allow reset of this condition.
RMS OverCurrent (FoldBack): The FoldBack detection system can ‘clamp’ the available output
current. This is not a true fault condition, but may cause undesired performance, due to the command
current being limited below what is required to achieve the desired performance. This condition is
indicated with a flashing ‘F’ in the status display and can be detected by monitoring the FOLD switch
variable.
Bus OverVoltage: An over-voltage condition shuts down the drive and displays a lower-case ‘o’ in the
status display. This fault occurs mostly during regen operation where the BUS is raised to higher values
than that produced by the power supply.
Bus UnderVoltage: An under-voltage condition shuts down the drive and displays an ‘u’ in the status
display. This fault normally occurs when the incoming line voltage drops out or a fault occurs in the
power supply. PowerStage Fault (OverCurrent): Hardware circuitry monitors load short-circuit, transistor failure,
and instantaneous OverCurrent. In general, toggling the Remote Enable cannot reset a power stage fault.
Power must be cycled. A flashing ‘P’ in the status display indicates this condition.
Low-voltage power supply faults: Out of tolerance values on the ± 12 VDC analog supplies will cause
an ‘A’ to be displayed and disable the drive.
OverSpeed fault: Software continuously monitors the actual (feedback) speed. If the motor speed
exceeds the VOSPD limit, a ‘J’ is displayed and the drive is disabled. This normally occurs when there
is an improperly-tuned system and the load overshoots its commanded speed.
No compensator: In case the SERVOSTAR cannot design a compensator (after a RSTVAR command,
CLREEPROM, or any change in the motor or drive parameters), a flashing minus sign (-) is displayed
and causes the drive to disable. This display normally indicates the drive does not have a compensation
file loaded.
Memory reliability: During the initialization process upon power up, the runtime, variables memory
(RAM - Random Access Memory), and the program memory (EPROM - Electrically Programmable Read
Only Memory) are tested.
