The temperature of the NTC thermistor and the junction temperature Tvj are different. The junction temperature Tvj becomes higher than the temperature of the NTC thermistor. The thermistor is mounted on the same insulating substrate as the IGBT chip but is away from the IGBT chip. It follows the junction temperature Tvj with an offset […]
An installation of 3 of our FRENIC-Ace inverters and an HMI with connection via MODBUS was implemented in a restaurant in Croatia to offer customers a 360º view of the city. The task was to control the motors that are simultaneously rotating the restaurant platform, avoid any failures, and analyze and collect feedback of the application.
Our inverters control 3 of their motors, offering power control, protection against failures, speed control and maintenance warnings. Meanwhile, our HMI gives access to analytic data like current, temperature, and more at any moment.
