BENTLY 184684-01位移監(jiān)測器
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)檢測到故障時,將其記錄在狀態(tài)顯示中指示的內(nèi)部錯誤日志中,通過串行端口發(fā)出,在大多數(shù)情況下會導(dǎo)致驅(qū)動器禁用。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)動器在裝置硬件和操作系統(tǒng)中檢測到的故障。
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(繼電器)斷開。
驅(qū)動器超溫: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)動器。驅(qū)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(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,可能會導(dǎo)致不期望的性能電流被限制在低于實現(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)檢測變量
總線過電壓:過電壓條件關(guān)閉驅(qū)動器,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)會關(guān)閉驅(qū)動器并在狀態(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,以及瞬時過電流。通常,切換遠(yuǎn)程啟用不能重置功率級故障。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)動器。
超速故障:軟件持續(xù)監(jiān)控實際(反饋)速度。如果電機(jī)速度超過VOSPD限制時,顯示“J”并禁用驅(qū)動器。這通常發(fā)生在:是一個調(diào)整不當(dāng)?shù)南到y(tǒng),負(fù)載超過其指令速度。
無補償器:如果伺服星無法設(shè)計補償器(在RSTVAR命令之后,CLEEPROM,或電機(jī)或驅(qū)動參數(shù)的任何變化),顯示閃爍的減號(-)并使驅(qū)動器禁用。此顯示通常表示驅(qū)動器沒有補償文件已加載。

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.
