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(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(wèn)題當檢測到故障時(shí)，將其記錄在狀態(tài)顯示中指示的內部錯誤日志中，通過(guò)串行端口發(fā)出，在大多數情況下會(huì )導致驅動(dòng)器禁用。許多故障可以重置通過(guò)切換硬件遠程啟用（遠程輸入）。以下是更常見(jiàn)的：驅動(dòng)器在裝置硬件和操作系統中檢測到的故障。
電機過(guò)熱：監控電機外部恒溫器輸入是否開(kāi)路條件用戶(hù)可以定義（使用THERMODE）在此故障條件下發(fā)生的情況。最壞的當狀態(tài)顯示中出現“H”且故障繼電器觸點(diǎn)（繼電器）斷開(kāi)。
驅動(dòng)器超溫：監控內部散熱器溫度是否處于不安全狀態(tài)。這條件導致顯示“t”并禁用驅動(dòng)器。驅動(dòng)器最終將冷卻到：允許重置此條件。
RMS過(guò)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(huì )導致不期望的性能電流被限制在低于實(shí)現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(guò)監控折疊開(kāi)關(guān)檢測變量

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.
