14 giu 2023 · A constant, single-polarity (DC) voltage is supplied to the leads. One or two pairs of spring-loaded carbon brushes cause the electricity to flow to the rotating rotor windings. When the motor turns one-half or one-quarter of a revolution, the electricity is flipped (or ‘commutated’) so that the magnetic field is reversed. Figure 1.

Feedforward Control. “Feedforward” is a rather under-used control strategy capable of managing a great many types of process problems. It is based on the principle of preemptive load counter-action: that if all significant loads on a process variable are monitored, and their effects on that process variable are well-understood, a control ...
Cascade Control - Nested Feedback Loops. To cascade controllers means to connect the output signal of one controller to the setpoint of another controller, with each controller sensing a different aspect of the same process. The first controller (called the primary, or archaically, master) essentially “gives orders” to the second controller ...
23 mar 2022 · Pulse width modulation (or PWM) can be used to better control variable loads. Load devices are designed to run efficiently and perform their respective tasks when provided with a certain voltage, consuming a particular amount of current. To change the parameters of the load, the voltage can be lowered, but this will often have negative effects ...
30 gen 2023 · The codes are two bytes long or one word (16 bit) of hexadecimal numbering with the most significant byte first or “big-endian”. Typically, each device on the Modbus network will have four memory registers: discrete inputs, coil outputs, input registers (input data), and holding registers (output data). These memory registers can be read or ...
Programmable Logic Controller - PLC. A forum for industrial controllers that can automate a specific process, machine function, or even an entire production line. LATEST. Issues running a program on the Arduino Opta. Program uploads just fine but won't execute.
Control valves configured to follow the command of the same controller are said to be split-ranged, or sequenced. Split-ranged control valves may take different forms of sequencing. A few different modes of control valve sequencing are commonly seen in the industry: complementary, exclusive, and progressive. Complementary valve sequencing
