6410-001-N-N-N power driver

The figure below shows the connections required between the 6410-001-N-N-N connector J3 and Pacific Scientific motors having flying leads. Connections are shown for 4 lead motors, 8 lead motors with paralleled windings, and 8 lead motors with series windings. Wire nuts may be used for the winding connections at the motor end.

The figure below shows the connections required between the 6410-001-N-N-N connector J3 and Pacific Scientific stepper motors having a terminal board in the rear end bell. Connections are shown for 4 lead motors, 8 lead motors with paralleled windings, and 8 lead motors with series windings.

Input that determines the direction of motor rotation. If standard motor wiring is followed, the motor will turn clockwise if the opto current is zero. The sense of the DIR + input can be reversed by reversing the connection of either (but not both) motor phase connectors (i.e. switching A & A OR B & B). Refer to the figure at the end of the table for timing and circuit information.

Input used to enable or disable the 6410-001-N-N-N’s power stage. With the J6 5-6 jumper out (factory default) the power stage is enabled if the opto current is zero and disabled if the opto is driven. Inserting the jumper reverses this functionality. See figure at the end of the table for circuit information. There is a delay of approximately 500 ms after enabling the drive and the power stage becoming active.

The application and development of FCS is a new type of distributed network control system, which is not only a field communication network system but also a field automation system. As a field communication network system, it has open digital communication function and can be interconnected with various communication networks. As a field automation system, it takes various field instruments installed on the production site with input, output, calculation, control, and communication functions as nodes of the field bus, and directly forms decentralized control loops on the field bus.

FCS represents the development direction of current control technology and DCS, and has entered the stage of industrial application. People have various comments on FCS, ranging from likes and dislikes of new technologies to confusion about the current situation. Despite various opinions, the author believes that currently FCS and DCS coexist. As an important branch of the application development under the DCS framework, FCS briefly expresses the following personal opinions: ① The transformation of FCS: not only has it transformed traditional single function analog instruments, but also has been transformed into comprehensive function digital instruments; Moreover, it has transformed the control station of traditional DCS by dispersing input, output, calculation, and control functions into fieldbus instruments, forming a control loop on the fieldbus, forming a completely digital decentralized control system The characteristics of FCS include seven aspects or advantages: system decentralization, system openness, product interoperability, environmental adaptability, ease of maintenance, system reliability, and economic use. Some people have objections to the “economy of use”, which is a normal temporary phenomenon. The reason is that FCS has not yet entered the stage of mass application, and the prices of fieldbus instruments and auxiliary equipment are on the high side. With the promotion and application of FCS, technological progress, market competition, and survival of the fittest, the economy of FCS will become apparent. Looking back at the time, DCS was also the same, and now people have fully accepted DCS Application of FCS: A typical industrial application example is the 900000 ton/year ethylene project of Shanghai SECCO.

DCS adopts Emerson’s Delta V system, and the control station is equipped with FF-H1 fieldbus modules in addition to conventional I/O modules. The two interfaces of each module form two sections of FF-H1 bus, and each section of FF-H1 bus is designed with 9 instruments (6 practical and 3 backup). This project involves 2473 FF-H1 field bus sections and 14375 FF-H1 field bus instruments, with an average of 5.8 instruments installed on each FF-H1 field bus section. The FF-H1 field bus section integrates field bus instruments from different manufacturers. In addition to Emerson’s temperature, pressure, flow and other instruments, there are also E+H radar level and flow meters, ABB’s valve locator, ROTORK’s electric motor controller, TYCO’s electric motor controller, etc., ensuring the consistency and interoperability of multiple products Integration of FCS: In small engineering projects, FCS is a self-contained system, while in medium to large engineering projects, FCS and DCS control stations are integrated in two general ways.

One type is the FF-H1 fieldbus module as a subordinate I/O module of the control station, such as Emerson’s Delta V system, as shown in Figure 3; Another type is the FF-H1 fieldbus module, which is independent, such as Honeywell’s Experion PKS R300 system, as shown in Figure 4. The former FF-H1 is attached to the controller, resulting in slow information transmission; The latter is FF-H1 independent and has fast information transmission. The engineer station (ES), operator station (OS), and computer station (CS) in Figures 3 and 4 are DCS operation monitoring layer devices. The control station has redundant power supply (P), controller (C), fieldbus interface (H1), and various I/O modules.
