BENTLY 184684-01位移监测器
SERVOSTAR CD-Lite的微处理器不断监控许多不同的状态组件。通常，所有故障条件都被锁定，因此您可以轻松确定问题当检测到故障时，将其记录在状态显示中指示的内部错误日志中，通过串行端口发出，在大多数情况下会导致驱动器禁用。许多故障可以重置通过切换硬件远程启用（远程输入）。以下是更常见的：驱动器在装置硬件和操作系统中检测到的故障。
电机过热：监控电机外部恒温器输入是否开路条件用户可以定义（使用THERMODE）在此故障条件下发生的情况。最坏的当状态显示中出现“H”且故障继电器触点（继电器）断开。
驱动器超温：监控内部散热器温度是否处于不安全状态。这条件导致显示“t”并禁用驱动器。驱动器最终将冷却到：允许重置此条件。
RMS过电流（回流）：回流检测系统可“箝位”可用输出现在的这不是真正的故障状况，但由于命令的原因，可能会导致不期望的性能电流被限制在低于实现期望性能所需的电流。这种情况是状态显示中以闪烁的“F”表示，可通过监控折叠开关检测变量
总线过电压：过电压条件关闭驱动器，并在状态显示。该故障主要发生在再生操作期间，此时总线升高到较高值而不是由电源产生的。
总线欠压
欠压状态会关闭驱动器并在状态中显示“u”陈列该故障通常发生在进线电压下降或电源。功率级故障（过电流）：硬件电路监控负载短路、晶体管故障，以及瞬时过电流。通常，切换远程启用不能重置功率级故障。电源必须循环。状态显示中闪烁的“P”表示此情况。
低压电源故障：超出±12 VDC模拟电源的公差值将导致将显示“A”并禁用驱动器。
超速故障：软件持续监控实际（反馈）速度。如果电机速度超过VOSPD限制时，显示“J”并禁用驱动器。这通常发生在：是一个调整不当的系统，负载超过其指令速度。
无补偿器：如果伺服星无法设计补偿器（在RSTVAR命令之后，CLEEPROM，或电机或驱动参数的任何变化），显示闪烁的减号（-）并使驱动器禁用。此显示通常表示驱动器没有补偿文件已加载。
内存可靠性：在通电初始化过程中，运行时、变量内存（RAM-随机存取存储器）和程序存储器（EPROM-电可编程读取仅存储器）进行测试。
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.
