The maximum holding torque values are as follows:CSK24Ⅺ: 22.2 oz-in (0.16N •m) ϳ44.4 oz-in (0.32N •m)CSK26Ⅺ:54.1 oz-in (0.39N •m) ϳ187 oz-in (1.35N •m)2.Powerful SH Geared TypeThe product line for the CSK series also includes the SH geared type that provides high torques. There are six gear ratios: 3.6:1, 7.2:1, 9:1, 10:1, 18:1, and 36:1.3.High-Resolution TypeThe product line for the CSK series also includes high-resolution types for which the basic step angle (1.8Њ/step) for the two-phase stepping motors is cut in half to 0.9Њ/step (for full steps).The resolution is doubled from 200 steps per revolution for standard types to 400 steps per revolution. The high-resolution type can be run in half-step mode to provide 800 steps per revolution.pact DriverThe drivers produce a high output of 2A/phase for 24V/36V DC.

When the photocoupler state changes from "ON" to "OFF", the motor rotates one step. The direction of rotation is determined by the following rotation direction signal.Rotation Direction SignalThe "Rotation Direction" signal is input to theDIR./CCW Ϫterminal. A "photocoupler ON" signal input commands a clockwise direction rotation. A "photocoupler OFF" signal input commands a counterclockwise direction rotation.2-Pulse Input Mode CW Pulse Signal"Pulse" signal is input to the PULSE/CW Ϫterminal. When the photocoupler state changes from "ON" to "OFF", the motor rotates one step in a clockwise W Pulse Signal"Pulse" signal is input to the DIR./CCW Ϫterminal. When the photocoupler state changes from "ON" to "OFF", the motor rotates one step in a counterclockwise direction.●All Windings Off (C.OFF) InputWhen the "All windings Off" (C.OFF) signal is in the"photocoupler ON" state, the current to the motor is cut off and motor torque is reduced to zero. The motor output shaft can then be rotated freely by hand.This signal is used when moving the motor by external force or manual home position is desired.●Excitation-Timing (TIMING) OutputThe signal is output once each time the excitation sequence returns to step "0" in synchronization with input pulses. The excitation sequence is designed to complete electrical one cycle as the motor shaft rotates 7.2˚. A signal is output every 4 pulses in full step mode (1.8˚/step) and every 8pulses in half step mode (0.9˚/step).Use a power supply that can supply sufficient input current.When power supply capacity is insufficient, a decrease in motor output can cause the following malfunctions:●Motor does not rotate properly at high-speed (insufficient torque)●Motor startup and stopping is slow.Use connector TB1 and TB2 when connecting.Note:●Keep the voltage Vo 1and Vo 2between DC 5V and DC 24V. When they are equal to DC 5V, the external resistances R 1and R 2are not neccessory. When they are above DC 5V, connect R 1to keep the current below 20mA, and connect R 2to keep the current below 10mA.●Use twisted-pair wire of 3.1ϫ10-4 in 2(0.2mm 2) or thicker and 6.6 feet (2m) or iess in length for the signal line.●Use wire 7.8ϫ10-4 in 2(0.5mm 2) or thicker for motor lines (when extended) and power supply lines, and use 1.2ϫ10-3 in 2(0.75mm 2) or thicker for the wire for the grounding line.●Use spot grounding for the grounding of the driver and external controller. ●Signal lines should be kept away at least 3.94 in. (10cm) from power lines(power supply lines and motor lines). Do not bind the signal line and power line together.ⅢTIMING CHARTCW Motor CCWPulseAll Windings Off Input ON OFFON OFFON OFFDirection✽1 It is recommended to wait a period of time to allow the motor oscillations toend before inputting the "All windings Off" signal. This time varies with the load inertia, the load torque and the starting pulse rate, Signal input must be stopped before the motor stops.✽2 Never input a step pulse signal immediately after switching the "All windingsOff" signal to the “photocoupler ON ” state or the motor may losesynchronism. In general, an interval of 100ms (minimum) is required.Response up to about 10 kHz with a pulse duty of 50%. When using it at higher speeds, narrow the pulse width.2. Adjusting the Motor Operating CurrentTo set the "Automatic Current Cutback" function to inactive (SW1:OFF):(1) Adjust the motor operating current with the RUNpotentiometer. It can be adjusted from 0.3A/phase to the rated value of the driver.(2) The motor operating current is set for the rated current at the time of shipping. The RUN potentiometer can be used lower the operating current to reduce temperature rise in the motor/driver, adjust torque margin and reduce vibration.ⅢSWITCHING AND SETTING FUNCTIONS 3. Adjusting The Current At Motor StandstillT o set the "Automatic Current Cutback" function to active (SW1:ON):(1) Adjust the current at motor standstill with the STOPpotentiometer. It can be adjusted from 25% to 40% of the run operating current (0.3A minimum).(2) At the time of shipping, the current at motor standstill is set for 40%. The STOP potentiometer readjusts the current to the value required to produce enough holding torque.(1) Automatic Current Cutback at motor standstill When switch 1 (ACD) is set to ON, the "Automatic CurrentCutback" function at motor standstill is active. Approximately 0.1seconds after input pulses stop, the motor output current is automatically lowered to suppress heat generation in the motor and driver. Generally, the switch should be in the ON position. (If the switch is set to OFF , the "Automatic Current Cutback"function at motor standstill is disabled.)(2) Step Angle Standard Type:When switch 2 (F/H) is set to ON, the driver is set for 1.8˚/step (200 steps per revolution. When the switch is set to OFF , the driver is set for 0.9˚/step (400 steps per revolution). High-Resolution Type:When switch 2 (F/H) is set to ON, the driver is set for 0.9˚/step (400 steps per revolution). When the switch is set to OFF , the driver is set for 0.45˚/step (800 steps per revolution).(3) Pulse Input ModeThe driver is designed to function under either of the following two pulse output modes on the user ’s controller:●When switch 3 (1P/2P) is set to OFF , the driver is set for the 2-pulse input mode, in which two types of pulse signal (one each for CW and CCW) are used to control the motor.●When switch 3 (1P/2P) is set to ON, the driver is set for the 1-pulse input mode, in which a pulse signal and a direction of rotation signal are used to control the motor.(4) Power Supply VoltageWhen using a 24V DC power supply, switch 4 (24/36V) should be ON. When using a 36V DC power supply, the switch should be OFF .ⅢADJUSTING THE OUTPUT CURRENT1.Adjustment MethodConnecting voltmeterInsert voltmeter test probes [approximately 0.18 in. diameter (2.1mm)] as shown below.The current value for one phase is equivalent to the voltage shown by the voltmeter.

兄弟铸万方行业创百强
----访沈阳市东方电机有限公司总经理鲁东全总经理鲁东全是一位充满智慧、知人善用的杰出领导者;是一位胸存博爱、情系员工的民营企业家;副总经理宋红哲是一个追逐理想,为了志向奋斗不息的追梦人;是一位诚诚实实做人,踏踏实实做事的实干家。
这就是扬名于沈北新区的兄弟企业----沈阳东方电机有限公司。
人生是不止一段风雨历程拼集起来的故事。
有人从某一个时间节点走进来,也有人从另一个时间节点走出去,还有人坚韧地延续着属于他们共同的故事。
这些坚韧的人是敢于站在摇曳的船帆上笑傲肆虐海峰的勇士,是面对骇浪惊涛也能沉稳避过暗礁湍流的忠魂。
也许,前行的航线上,时间的浪涛冲刷了太多的印迹,但淘金后留下的,是璀璨如珍珠般耀眼的传奇……
这个传奇来自东方。
东方人用勤奋和挚诚诠释了企业的壮大之路,用智慧与意志见证了“至诚一心,重责自强”的风雨历程,一跃成为辽宁省行业百强企业。
长期以来我国内装备制造业一向重主机、轻配套的发展思路,致使大型铸锻件,以及液压件、密封件等基础零件等基础零件一直成为制约我国大型成套设备发展的瓶颈。
“这些零部件看起来不大,其经济效益比较可观,而且具有很强
的战略意义。
”提及前不久出台的装备制造业调整振兴计划,总经理鲁东全颇为感慨。
他表示,“希望规划能进一步细化、落实,同时尽快建立完善的机制,对大型铸锻件的技术水平提升起到实实在在的促进作用。
”
“近年来国家不断加大重大装备国产化力度。
东方也投入巨资开展技术攻关,提升大型铸锻件尤其是军工锻件的技术水平和生产能力,目前公司已形成了大型铸锻件的制造基地。
”他表示说,至于高端产品研制难,还是源于成套能力不足。
“比如,目前我们的大型铸锻件还需要大吊车吊起来,这导致效率的低下。
部分企业的油压机、水压机与旁边的操作机并不匹配,结果设备虽好,但却没能发挥应有的作用。
”
“这还与以往重视程度不够、研发投入太少有关系。
”鲁东全指出,“至上世纪八十年代以来,一些研发经费完全依靠国家投资,投资不到位研发就难以进行。
公司下一步会成立一个专家组,认真研究行业发展的症结所在,究竟缺什么,到底需要多少资金,然后根据认证结果进行整体的规划部署。
”
目前的重大装备已经非常先进,差距还在软环境上。
大型铸锻件在大型火力、水力、核电、大型轴承锻件等方面的问题还没完全解决。
热加工要比冷加工难得多,它还包括长久积淀的经验、工艺等那些看不到、摸不到的技术。
要提升大型铸锻件、基础部件、加工辅具、特种原材料
等配套产品的技术水平,夯实产业发展基础。
“现在国家充分支持我国大型铸锻件发展,希望整个行业能充分把握这次难得的机遇。
”弟弟宋红哲补充说。
鲁东全审时度势,以新的经营思维去应对客运市场的挑战,整合资源,发挥比较优势。
一是树立品牌意识,不断提高服务质量。
他始终坚持以人为本的经营理念,改变服务观念,提高服务质量,树立文化窗口。
积极参加市里组织的一系列主题竞赛活动,充分调动广大员工爱岗敬业、钻研业务的积极性,形成了努力打造东方的工作氛围,让每位客户都体会到企业内涵;二是把落实安全制度,做为企业发展根本。
公司专门成立了安全工作领导小组,坚持安全生产,杜绝安全生产事故,让员工高高兴兴上班,安安全全下班;三是维护员工合法权益,企业与工会签订集体合同。
在他的倡导下,每年工会都召开会员代表大会,为广大员工更好地参与企业管理提供了平台,同时为了增加企业管理的透明度,还从工资福利、女工权益保护和劳动安全卫生几方面,与企业进行协商,签订集体合同,保护员工的权益。
鲁东全还用文化管理企业,用精神统领员工。
企业文化是企业的发展之魂,也是企业持续发展的不竭动力,这一点,他早有认识。
他说,企业的竞争归根到底是文化的竞争,企业文化是企业的生命之源,是企业成熟的标志,只有让企业文化起来,才能真正实现企业可持续发展和科学发展,企业
才会有恒久和活力。
在企业文化建设方面,建立了一种企业员工共享的价值观和行为准则,通过建立共同的价值观和企业精神,提高企业的向心力和凝聚力,把员工凝聚在企业周围,激发职工积极性和力量汇聚到企业的整体目标上,从而提高企业的经济效益和社会效益。
现如今东方生产的各类模锻、胎模锻、自由类锻、所涉及的钢种有碳钢类、模具钢、不锈钢、合金钢、轴承钢、工具钢、弹簧钢等,销路已经遍布国内外。
早已摆脱金融风暴企业的低谷时期,从而迎来万方人异军突起的行业巅峰。
先后被授予:中国市场信誉企业、辽宁省行业百强企业、辽宁市场信誉品牌、辽宁省社会公益事业优秀单位;公司的生产能力和技术设备在同行业中达到了领先地位。
去年鲁东全又被授予“自主创新优秀企业家”称号,一个企业的壮大从来都不是一夜成就的,一个品牌的树立也不是一朝一夕的,一个优秀管理者的成长也不是渐修顿悟就可以达到的,凡事都要经历一定量的积累才能达到质的突变。
这样浅显的道理对于任何怀揣梦想同时又踏实肯干的奋斗者来说都是再明白不过的,然而真正把简单的事情做成功并且经年累月一直坚持下来却并不是那样轻而易举,也正因此,做到的这些成为了最终的收获者。
创业,看似简单,却凝聚着无限的勇气和智慧。
兄弟俩的奋斗成为万方集团的助推剂,专业化的发展道路必将成就立足于辽宁工业基地的双
骄!。
