PM864AK02 Signal processor module

The motor control performance is significantly improved, and it can achieve control of asynchronous motors and permanent magnet synchronous machines, supporting multiple PG cards, IO cards (including CAN communication), and more powerful functions. It can be used for various electrical transmission equipment such as textiles, papermaking, machine tools, packaging, food, lifting, lifting, petroleum machinery, chemical machinery, fans, water pumps, etc.

The S500 series frequency converters have significantly improved in the following aspects:

1. Rich support for motor types: supporting three-phase AC asynchronous motors and three-phase AC permanent magnet synchronous motors;

2. Rich control methods: speed sensor vector control (FVC), speed sensorless vector control (SVC), V/F control, V/F separation control;

3. Rich fieldbus: supports Modbus RTU and CANlink buses;

4. Rich encoder types: supporting differential output encoders, open collector (OC) or push pull output encoders;

5. A new speed sensorless vector control algorithm that provides better low-speed stability, stronger low-frequency torque, and supports SVC torque control;

6. A powerful external expansion card that can achieve CAN communication function, injection molding machine function, motor PT100 thermal protection function, etc;

EIn fact, it is achieved by controlling several DI terminals of the frequency converter to operate at the corresponding set frequency through different combination states. If I define DI1 and DI2 terminals as multi-stage speed control terminals, the two terminals will be combined into four states, namely 00, 01, 10, and 11. In the frequency converter, the frequency values corresponding to the four states are defined, assuming they are 10Hz, 15Hz, 25Hz, and 40Hz, then when DI1 is 0, When DI2 is 1, the frequency converter will output a frequency of 15Hz. The same applies to other combinations. By continuously switching the states of these two input points, the frequency converter can be controlled to operate at the corresponding frequency.

 and the natural energy consumption has also been reduced by one eighth, indicating that the gearbox has achieved energy-saving of the main ventilation fan. Moreover, most coal mines use a fan to drive two motors, so based on this feature, one frequency converter can simultaneously control the normal operation of both motors. Regardless of the driving method used to control the power of the frequency converter, the total power cannot be smaller than the sum of the two motors.

By using the i550 MOTEC frequency converter, Lenz can achieve transparency in the process from the transmission shaft to the cloud for our customers and support their digital transformation.

The IO Link master station function equipped with the i-series MOTEC frequency converter provides real-time recognition and diagnostic data from sensors, allowing for easy data exchange between IO Link sensors and actuators. By using Drive DataHub to connect to the cloud, it also saves additional hardware and installation costs, and performs well in status monitoring or predictive maintenance.

Today we will explain an important concept of frequency converters: frequency sources, and some brands may refer to them as given channels. In fact, what we are talking about is the same thing. Previously, as long as a running command was given to the frequency converter, it was already running. However, if the frequency was not given and the frequency was set to 0 at this time, even if the frequency converter was already running, the motor would not rotate due to the output frequency of the frequency converter being 0. Therefore, in general, both the command source and frequency source need to be given simultaneously. The command source is responsible for starting and the frequency source is responsible for controlling the speed, Only in this way can a frequency converter be used to control the motor for speed regulation.
