Purpose and ability of Triol AT24 variable frequency drive

12/15/2016

Variable frequency drive Triol AT24 is multifunctional system that supports control asynchronous (inverter) electric pump motor with different purpose. It can operate individually as well, as can be integrated into different control system while the additional interface units are being installed.

Variable frequency drive’s control system is based on modern high-performance dual core microprocessor and realizes all functional operation mode. Modern technologies with IGBT transistor (Insulated Gate Bipolar Transistor) are used in power scheme. As a result Triol AT24 VFDs have the high-reliability and various functions:

• start, stop, pump motor speed control;

• acceleration and braking with adjusted pace;

• reversion;

• acceleration, deceleration, stop;

• protection motor from short-circuit current;

• pump control from external two- and three-wire sensors;

• conservation of configuration control;

• motor dynamic braking;

• control of five pump motors simultaneously (macros “Cascade Controller”);

• automatic control of technological processes in a closed-loop system with a built-in PID-controller;

• Automatic Asynchronous motor restart;

• “soft start” capability for a motor (the motor can be ramped up to desired speed instead of being turned on at full RPMs), decreasing the mechanical stresses associated with full-voltage start-ups. It cost a longer motor life. In cyclic loads, the VFD also helps to avoid motor overheating.

If you are looking for improved process control, energy savings, higher reliability – Triol AT24 VFD is what you need!
