40PB3203A回路I/O板
超溫SMC Flex控制器使用參數(shù)119中的值來(lái)監(jiān)控使用內(nèi)部熱敏電阻測(cè)量SCR和旁路的溫度。當(dāng)達(dá)到電源極的最高額定溫度，機(jī)組關(guān)閉禁止停機(jī)和重啟。
溫度過(guò)高可能表示通風(fēng)不足、溫度過(guò)高環(huán)境溫度、過(guò)載或過(guò)度循環(huán)。溫度升高后如果降低到允許的水平，則可以清除故障。
打開(kāi)大門門開(kāi)路故障表明SCR點(diǎn)火不正確，通常是由在其中一個(gè)電源極上檢測(cè)到SCR門打開(kāi)。在控制器關(guān)閉時(shí)，它總共嘗試啟動(dòng)電機(jī)三次。線路故障
SMC Flex控制器持續(xù)監(jiān)控線路狀況是否異常因素。啟動(dòng)前保護(hù)包括：
?線路故障（帶相位指示）
-線路電壓損失
-缺少負(fù)載連接
-SCR短路
運(yùn)行保護(hù)包括：?線路故障（無(wú)相位指示）
-線路電壓損失
-缺少負(fù)載連接
您可以打開(kāi)或關(guān)閉反相保護(hù)。反相保護(hù)僅在預(yù)啟動(dòng)時(shí)起作用。
測(cè)量
電源監(jiān)測(cè)參數(shù)包括：
?三相電流（參數(shù)4、5和6）
?三相電壓（參數(shù)1、2和3）
?功率（kW）（參數(shù)7）
?用電量（千瓦時(shí)）（參數(shù)8）
?功率因數(shù)（參數(shù)11）
?電機(jī)熱容量使用（參數(shù)12）
?經(jīng)過(guò)時(shí)間（參數(shù)9）
帶制動(dòng)控制的智能電機(jī)制動(dòng)、Accu Stop和慢速選項(xiàng)。
經(jīng)過(guò)的時(shí)間和kWH值會(huì)自動(dòng)保存到上的存儲(chǔ)器中斷電。
電機(jī)熱容量利用率由內(nèi)置電子散熱片決定超載。當(dāng)該值達(dá)到100%時(shí)，發(fā)生過(guò)載故障。
輸入/輸出SMC Flex控制器最多可接受兩個(gè)輸入和四個(gè)輸出通過(guò)網(wǎng)絡(luò)控制。這兩個(gè)輸入在端子16（選項(xiàng)輸入#1，參數(shù)132）和端子15（選項(xiàng)輸入#2，參數(shù)29）。對(duì)于這兩個(gè)輸入，參數(shù)設(shè)置見(jiàn)表26，表39和表40為鉆頭標(biāo)識(shí)。
您可以通過(guò)以下方式對(duì)停止輸入進(jìn)行編程，以滿足所需的停止功能使用這兩個(gè)端子作為輸入。
這四個(gè)輸出是Aux#1（參數(shù)107）、Aux#2（參數(shù)110）和Aux#3（參數(shù)108）和輔助#4（參數(shù)109）。所有輔助觸點(diǎn)均為可編程為表26中的功能。如果輸出編程為網(wǎng)絡(luò)或網(wǎng)絡(luò)NC，可以通過(guò)網(wǎng)絡(luò)見(jiàn)表40，它定義了邏輯命令字（控制）。表達(dá)串行接口端口（DPI）是作為標(biāo)準(zhǔn)提供的，它允許您連接SMC Flex控制器與公告20HIM LCD接口的連接模塊。
圖22-DPI位置您可以將兩個(gè)外圍設(shè)備連接到DPI。最大輸出功率通過(guò)DPI的電流為280 mA。
Overtemperature
The SMC Flex controller uses the value in Parameter 119 to monitor the temperature of the SCRs and Bypass by using internal thermistors. When the maximum rated temperature of the power poles is reached, the unit shuts down and restart is inhibited. An overtemperature condition can indicate inadequate ventilation, high ambient temperature, overloading, or excessive cycling. After the temperature is reduced to allowable levels, the fault can be cleared. Open Gate An open gate fault indicates that improper SCR firing, typically caused by an open SCR gate, has been detected on one of the power poles. Before the controller shuts down, it attempts to start the motor a total of three times. Line Faults The SMC Flex controller continually monitors line conditions for abnormal factors. Pre-start protection includes: ? Line Fault (with phase indication) - Line voltage loss - Missing load connection - Shorted SCR Running protection includes: ? Line Fault (no phase indication) - Line voltage loss - Missing load connection You can toggle Phase Reversal protection either On or Off. Phase Reversal protection is functional only at pre-start. Metering Power monitoring parameters include: ? Three-phase current (Parameters 4, 5, and 6) ? Three-phase voltage (Parameters 1, 2, and 3) ? Power in kW (Parameter 7) ? Power usage in kWH (Parameter 8) ? Power factor (Parameter 11) ? Motor thermal capacity usage (Parameter 12) ? Elapsed time (Parameter 9)
Voltage measurement
is not available during the braking operation of the Smart Motor Braking, Accu-Stop, and Slow Speed with Braking control options. The elapsed time and kWH values are automatically saved to memory on power down. Motor thermal capacity usage is determined by the built-in electronic thermal overload. An overload fault occurs when this value reaches 100%. I/O The SMC Flex controller can accept up to two inputs and four outputs that are controlled over a network. The two inputs are controlled at terminal 16 (Option Input #1, Parameter 132), and terminal 15 (Option Input #2, Parameter 29). For these two inputs, see Table 26 for the parameter settings and Table 39 and Table 40 for the bit identification. You can program the Stop Input to meet the desired stop functionality by using these two terminals as inputs. The four outputs are Aux #1 (Parameter 107), Aux #2 (Parameter 110), Aux #3 (Parameter 108), and Aux #4 (Parameter 109). All auxiliary contacts are programmable to the function found in Table 26. If the outputs are programmed to Network or Network NC, they can be controlled over a Network. See Table 40, which defines the Logic Command Word (Control). Communication A serial interface port (DPI) is provided as standard, which lets you connect the SMC Flex controller connection to the Bulletin 20-HIM LCD interface modules. Figure 22 - DPI Location You can connect two peripheral devices to the DPI. The maximum output current through the DPI is 280 mA.
