BENTLY 184684-01位移監測器
SERVOSTAR CD-Lite的微處理器不斷監控許多不同的狀態組件。通常，所有故障條件都被鎖定，因此您可以輕松確定問題當檢測到故障時，將其記錄在狀態顯示中指示的內部錯誤日志中，通過串行端口發出，在大多數情況下會導致驅動器禁用。許多故障可以重置通過切換硬件遠程啟用（遠程輸入）。以下是更常見的：驅動器在裝置硬件和操作系統中檢測到的故障。
電機過熱：監控電機外部恒溫器輸入是否開路條件用戶可以定義（使用THERMODE）在此故障條件下發生的情況。最壞的當狀態顯示中出現“H”且故障繼電器觸點（繼電器）斷開。
驅動器超溫：監控內部散熱器溫度是否處于不安全狀態。這條件導致顯示“t”并禁用驅動器。驅動器最終將冷卻到：允許重置此條件。
RMS過電流（回流）：回流檢測系統可“箝位”可用輸出現在的這不是真正的故障狀況，但由于命令的原因，可能會導致不期望的性能電流被限制在低于實現期望性能所需的電流。這種情況是狀態顯示中以閃爍的“F”表示，可通過監控折疊開關檢測變量
總線過電壓：過電壓條件關閉驅動器，并在狀態顯示。該故障主要發生在再生操作期間，此時總線升高到較高值而不是由電源產生的。
總線欠壓
欠壓狀態會關閉驅動器并在狀態中顯示“u”陳列該故障通常發生在進線電壓下降或電源。功率級故障（過電流）：硬件電路監控負載短路、晶體管故障，以及瞬時過電流。通常，切換遠程啟用不能重置功率級故障。電源必須循環。狀態顯示中閃爍的“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致將顯示“A”并禁用驅動器。
超速故障：軟件持續監控實際（反饋）速度。如果電機速度超過VOSPD限制時，顯示“J”并禁用驅動器。這通常發生在：是一個調整不當的系統，負載超過其指令速度。
無補償器：如果伺服星無法設計補償器（在RSTVAR命令之后，CLEEPROM，或電機或驅動參數的任何變化），顯示閃爍的減號（-）并使驅動器禁用。此顯示通常表示驅動器沒有補償文件已加載。
內存可靠性：在通電初始化過程中，運行時、變量內存（RAM-隨機存取存儲器）和程序存儲器（EPROM-電可編程讀取僅存儲器）進行測試。
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.
