速度反馈方式选择
调速器可以选择不需要任何硬件连接的电枢电压反馈或下面介绍的直流测速发电机作反 馈。最后还有编码器反馈,在接下来的一页中会有介绍。
直流测速发电机反馈:
T3
端子
60-180V 41
20-65V 42
44
8-25V 43
直流测 速电机
举例: 假如测速发电机的额定电压是 DC110V ;额定转速是 2000RPM。当转速为 1500rpm 时, 电 压是:110×1500/2000=82.5V.所以选择 41 号端子,然后调节 T3 电位器调节主电机速度。
SCR 使能- 数字量输入 1 是控制 SCR 电枢和励磁触发的使能输入,因此当这个触点断开时调速器将 滑行至停止如同接触器辅助触点断开或紧急制动时 SCR 触发立即消失一样。使用一个辅助触点通过 主交流线路接触器来使能数字量输入 1 是很重要的,它将补偿主接触器的关断时间。 运行- 数字量输入 2 对于这些连接,当运行开关闭合时,调速器将根据斜坡 1 设置的加速时间来运 行,当运行开关断开时,调速器将根据斜坡 1 设置的减速时间来停止。输入 2 同时还可以使能继电器 触点。 正转/反转- 数字量输入 3 对于 4Q 调速器这个输入会通过关闭一个方向的晶闸管开启另一个方向的 晶闸管来改变电机的旋转方向。 点动- 数字量输入 4 点动功能将从关闭状态使能,并且它的速度取决于 quickstart 菜单中的点动设置。 在调速器运行状态下,该功能是不起作用的。 快速停止- 数字量输入 5 通常快速停止是一直使能的,因而允许运行功能,然而如果快速停止触点断 开,调速器将根据斜坡 2 设置的减速时间停止。快速停止可自定义,如果需要可以将快速停止时间设 为 0。 复位- 数字量输入 7 这个输入可以被选做通过一个开关来复位调速器的错误报警。如果没有选用此 功能,也可以同时按住 键和 E 键来复位报警。 电机外部保护元件输入- 数字量输入 8 如果数字量输入 8 此功能未用,这个输入应该连接到+24v 电 源。当使用此功能时,如果此开关断开,则调速器将停止并显示“external”报警。

Symbol ConventionsThe symbols that may be found in this document are defined as follows.Symbol DescriptionProvides additional information to emphasize or supplement important points of the main text.Indicates a potentially hazardous situation, which if not avoided, could result in equipment damage, data loss, performance degradation, or unexpected results.Indicates a hazard with a high level of risk, which if not avoided, will result in death or serious injury.1 Introduction1.1Product Introduction0300P series 100 Mbps PoE switches are layer 2 PoE switches, providing advanced PoE power supply technology on the basis of high-performance access. The devices support up to 300 m long-range transmission (EXTEND mode), and feature high-priority ports to ensure preferential network transmission in key service areas of users. The devices also support port isolation to guarantee information security, and can enable PoE watchdog to automatically detect and restart ports. The devices are reliable, easy to install and maintain, and equipped with rapid switching functions. With multiple access ports, the devices are suitable for small-scale LAN device access.1.2Packing ListAccessory QuantitySwitch × 1Power Cord × 1L-Shaped Bracket × 2Screw Without Indicator Panel × 4 With Indicator Panel × 6Quick Start Guide × 1Multilingual Information ofNetwork Switch× 11.3AppearanceDevice appearances vary with different models.

The only difference is that 0326P series switches feature twenty-four 10/100 Mbps PoE RJ45 ports. ● The front panels of 0326P series switches (with indicator panels) are similar to those of 0318P series switches (with indicator panels). The only difference is that 0326P series switches feature twenty-four 10/100 Mbps PoE RJ45 ports, twenty-four portstatus indicators, and twenty-four PoE status indicators.Port/Indicator Description of Front PanelNo.Indicator/PortDescription1 PWR Indicator● Solid on: The switch ispowered on normally.● Unlit: No power supply isconnected or power supply is abnormal.2 PoE-MAX Indicator● Solid on: The output powerof the switch is about to reach or has reached the upper limit.

Ports in the sameisolation group cannotcommunicate with eachother. Data transmission viaeach port is isolated toenhance network security.Note● Ports 1 to 8 of 0318P and 0326P series switches are high-priority ports used to prioritize network transmission in keyservice areas.●When the DIP switch isswitched to “OFF”, port isolation is disabled. Ports can communicate with each other.9PoE Watchdog DIP SwitchEnable or disable PoE watchdog.● When the DIP switch is setto “ON”, PoE watchdog is enabled to automatically detect device connection statuses of corresponding ports and restart ports in case of communication failures.● When the DIP switch is setto “OFF”, PoE watchdog is disabled. Corresponding ports are no longer automatically detected and restarted in case of communication failures.1010/100 Mbps PoE RJ45 PortUsed for connection to a PD via a network cable.11Gigabit Combo Port (G1/G1-F)When connected to a network cable, the combo port is a RJ45 port. When plugged into with an optical module and connected to an optical fiber, the combo port functions as a fiber optical port.Note● A combo port consists of aRJ45 port and a fiber optical port. You can use either the RJ45 port or the fiber optical port of a combo port, but cannot use them at the same time. For example, if RJ45 port G1 is connected, fiber optical port G1-F is unavailable. ● When connected to both anetwork cable and an optical fiber, the combo port works as a fiber optical port.12Gigabit Combo Port (G2/G2-F) Gigabit RJ45 Port (G2) (when the devices feature only one combo port G1/G1-F)Used for connection to another device via a network cable.● Ports supporting long-range transmission vary with devicemodels. Ports 9 to 16 of 0318P series switches and ports 17 to 24 of 0326P series switches support up to 300 m network transmission.● Ports supporting port isolation vary with device models. Ports1 to 16 of 0318P series switches and ports 1 to 24 of 0326P series switches support port isolation.● Ports supporting PoE watchdog vary with device models.

开关触点配置快速指南
无论是寻找按钮、微型开关、摇臂开关、旋转开关还是拨动开关,最好记住基本的开关配置。

开关必须至少具有两片称为触点的导电材料。

触点连接至外电路,基本操作是接通触点或断开触点,使电路打开或关闭。

接通即打开电路,断开即关闭电路。

不同开关的配置可能有所不同,这取决于刀和掷的数量。

刀为触点组的数量,而掷为传导位的数量。

刀和掷
常见配置:
∙单极单掷,缩写为SPST
∙双极单掷,缩写为DPST
∙单极双掷,缩写为SPDT
∙双极双掷,缩写为DPDT
简要概述和常见图解
SPST –简单的双控开关,开关内仅有一条电路和一个接通位置。

DPST –开关内可同时操作两条电路,同时切换两条开关电路,还可用于隔离带电电路和中性电路。

SPDT –用于在两个位置接通,在独立电路之间切换。

L1可为警示灯,L2可为发声器。

该配置又称为转接开关,因配备第三个切换位置,还可以中间位置断开。

DPDT –有两个瞬动开关同时操作,同时切换两个装置,例如警示灯和发声器,相当于两个SPDT开关。

具有中间位置断开的DPDT可用于电机控制,使用正转反转操作。
