Mid-speed instability and the resulting loss of torque occurs in any step motor/drive system due to the motor back EMF modulating the motor winding currents at certain speeds. Mid-speed instability can be explained as a region of potential instability that occurs as a result of the electronic, magnetic, and mechanical characteristics of any stepping motor system. The circuitry used to control this phenomenon does so by advancing or delaying the switching of the output current with respect to the incoming pulse train.

This should be taken into account if the user is attempting to employ pulse placement techniques. Enable the digital electronic damping function by placing DIP switch S1 position 4 in the open position as shown. This is the default position and should be used for most applications if your application is affected by loss of torque at mid-range speeds. If pulse placement techniques are being used, disable the digital electronic damping function by placing DIP switch S1 position 4 in the open position.

The Idle Current Reduction (ICR) function reduces the phase current at times when no motion is commanded. Motor current is reduced when no step commands are received for a given time. This time can be set to 0.05 seconds, 0.1 seconds or 1.0 second. Current to both motor windings is reduced by one-half. The ICR function can be enabled/disabled and the time delay between the last step command and current reduction can be set to 50 ms, 0.1 seconds, or 1.0 second using DIP switch S1 position 5 and Jumper J6 position 7-8. With the jumper installed (factory default), ICR is disabled when DIP Switch S1 position 5 is in the closed position and enabled with a delay of 0.1 second (current is reduced by 50% when no step command is received for 0.1 second when the switch is open. With the jumper removed, ICR is enabled and the delay can be set to 0.05 second or 1.0 second by placing DIP Switch S1 position 5 in the closed or open position respectively.

The 6410-006-N-N-N drives are designed for minimum maintenance. The following cleaning procedure, performed as needed, will minimize problems due to dust and dirt build-up.

DCS and FCS provide conditions for the application of advanced control technology, and advanced control software is integrated into the system as an optional component of DCS. The commonly used advanced control technologies mainly include the following:

1. Single loop tuning technology: Single loop PID control always occupies the dominant position in process control, but its robust performance is not ideal, and it shows obvious shortcomings for processes with large delays and strong disturbances. To this end, a single loop model predictive control has been developed, which automatically adjusts control parameters and is suitable for processes with large delays and strong disturbances. For example, the Profit Loop Single Input Single Output (SISO) model predictive control algorithm in Honeywell’s Experion PKS R300 system

2.Soft instrument technology: This is based on a process mechanism model or statistical model, which estimates the main parameters of the product online and involves the estimated parameters in online control of product quality. For example, Honeywell’s Profit GCC software package for switching between atmospheric and vacuum crude oil

3.Multivariable model predictive control technology: This is the core technology of advanced control, which first identifies the process model, then estimates the process parameters and controlled variables, and compares them with the required target values. If there is a deviation, the optimal control quantity is calculated to achieve multivariable control of the entire device. For example, Honeywell’s RMPCT software package and Aspen Technology’s DMC-plus software package.

4.Online optimization technology: This is based on a process mechanism model and dynamic optimization technology, identifying the optimal operating points, and then implementing optimization operations through a multivariable controller. For example, Honeywell has developed dynamic optimization software based on Profit Optimizer, Profit Bridge, and mechanism models, which has been applied to ethylene and refining units

5.Performance monitoring and maintenance technology: The benefits of advanced control are relatively high in the initial stage of operation, but with the increase of operating time, changes in device performance, model mismatch, and operational changes, the performance of advanced control is reduced, and the economic benefits also decrease. To this end, developers have launched advanced control performance monitoring and maintenance tool software to maintain the benefits of advanced control. For example, Honeywell developed Scout software and Aspen Technology developed Aspen Watch software. In the future, promoting the application and development of DCS, FCS, and advanced control technologies is expected to be led by the process industry, especially the petroleum and chemical industries. Under the guidance of the national policy of “informatization drives industrialization, industrialization promotes informatization”, it is bound to usher in a spring of application and development of DCS, FCS, and advanced control technology.
