The general operating environment temperature of the inverter is generally required to be between -10°C and +50°C. In order to ensure the reliable operation of the frequency converter and extend the service life of the frequency converter, the inverter must be cooled. In winter, the built-in fan of the inverter can be used to take away the heat inside the inverter cabinet; the summer temperature itself has 40°C, and the internal heat taken away by the built-in fan of the inverter can only increase the temperature of the indoor and inverter cabinets
Q1. What is the difference between torque control and torque limiting?
A1 :Torque control can be done with any of our PID capable drives. Torque control would be a closed loop system where the process variable would be torque. You would have both a torque reference and torque feedback signal. The user would establish a torque signal and allow the drive to control to that set point. Many customers have used torque sensors, load cells, and current transducers to establish an analog input to the drive. Ideally a vector drive would work better than a volts/hertz drive. A vector drive would allow tighter speed regulation and better control in the lower speed range. Torque limiting can be done with series drive. Instead of using an external torque sensor, torque limiting uses the drive's internal current sensor. The operator would set the torque limit, and when that level is exceeded, the drive would act like a governor on a generator. The speed would be restricted until the appropriate level is again maintained. Mechanical devices, in addition to drives, are also employed for torque limiting. Items such as clutches, shear pins, gearboxes, and etc.
