Pacific PC832-001-N brushless servo drive

Pacific PC832-001-N brushless servo drive


This output can be connected to the customer’s hardware electronic stop chain and/or used to control a relay that energizes the coil of the motor’s safety cutoff brake. Before use, the driver normal/braking output (J1) must be defined as braking output through the I/O configuration wizard, as shown in the ToolPAC wizard in Figure 5-4. If the driver malfunctions, the brake output will be disabled. When the software is configured for the driver to output normally, as long as there are no faults, the output will be activated. (This does not mean that the controller is enabled!) When the software is configured for brake output, the output is only activated when the main power is turned on, the device is enabled, and there are no fault conditions present. The brake output is only wired in applications where the brake is used to maintain the motor position when the motor is not activated. The relay output becomes effective after 200ms at the forefront of the enable signal. If there is a fault or the drive is disabled, this output will immediately become inactive. The user does not have software control over this output.

ToolPAC supplies the tools necessary to configure the amplifier to your application. The screen images and descriptions provided in this section are intended to highlight some of the major features available within the software. ToolPAC Wizards for Setup, Tuning and I/O Configuration are provided to step the user through the basic configuration of the system. A dual trace scope is provided to allow the user to capture data on the commanded and actual motor motion. ToolPAC provides HELP on commands, parameters, features and functions available within the 3400 Series product line. Review this section to familiarize yourself with the features available prior to programming the unit. This will save time in the startup of a new application.

In the pressure swing adsorption device, the program control system has 6 program control valves for each adsorption tower. Under normal circumstances, 48 program control valves of the eight adsorption towers are opened and closed according to predetermined steps and switching times to achieve adsorption, average pressure drop, and other processes. When the following situations occur, the DCS system will automatically detect and alarm: 1) An external component of a program control valve malfunctions; 2) The execution mechanism of a certain adsorption tower program control valve is malfunctioning; 3) The control output module of an adsorption tower has malfunctioned; 4) The pressure transmitter of an adsorption tower is faulty. If it is in automatic program switching mode at this time, the DCS system program will consider automatically switching to 6 tower operation in the most suitable step sequence, so that production can proceed continuously and stably. If it is in manual switching mode at this time, the operator will select the corresponding tower according to the alarm prompt on the screen, cut it off, and the program will also consider automatically switching to tower 6 for operation in the most suitable step sequence. On the contrary, after the fault is resolved, the program also needs to consider the step-by-step switching from tower 6 to tower 8. The time setting for each step can be manually set, or an adaptive control method can be selected, and the DCS program automatically sets its time based on the working conditions.

In the whole program control system, the control program in DCS system is written in CL language provided by Daltav system. The program is of modular structure, including initialization program, main program, operation program of each tower, pressure detection program of each tower, valve inspection program, periodic calculation program, program control loop and other program modules. Each module is hung on the corresponding program point to realize its own functions. At the same time, through the flexible application of logic points, flow charts, and intermediate numbers, CL programs are better integrated with process control. The entire PSA program is composed of 20 program modules, including a sequence control main program block, timing block, manual valve program block, etc. The configuration of each program block is implemented using multiple modules such as ACT block and DO block. Its core module is the ACT function block.

ACT block based on input IN_ When D is set to 1, perform expression evaluation. The writing of expressions is mainly based on IF (expression) THEN (expression) ENDIF conditional statements. During configuration and programming, corresponding control programs are developed based on the action sequence diagram of the programmable valve. The control program is implemented using a large number of ACT functional modules, such as defining a corresponding ACT functional module during configuration, Add an expression to this function block to implement the corresponding control function (right-click on the CAT block and select Expression to open the expression writing dialog box for control program writing) If ‘LP. CV’ >=1 and ‘LP. CV <=15 THEN’ PSAC2/KV1A. CV ‘:=1 ENDIF if’ LP. CV ‘>=6 and’ LP. CV <=20 THEN ‘PSAC2/KV1B. CV’:=1 ENDIF This expression means that if the CV value of the ACT module LP is greater than 1 but less than 15, the KV1A valve opens. When the CV value of the LP is greater than 6 but less than 20, the KV1B valve opens.
