PPD113 CPU

These drive systems can operate over a wide range of speeds (such as large logistics systems), thus allowing for streamlined versions. The power range of NORDAC ON can reach 2.6kW, while NORDAC ON+can reach up to 3kW. These two inverters are integrated with industrial Ethernet interfaces. Whether it is Profinet, EtherNet/IP, or EtherCAT, the required protocols can be easily set through parameters, and firmware updates can also be achieved through Ethernet. Therefore, NORDAC ON/ON+frequency converters are very suitable for integration into industrial IoT environments. The device also includes diagnostic interfaces, M12 connectors for sensors and actuators, and a protocol based encoder interface with NORDAC ON+attachment, which has good anti-interference protection.

The principle of a leakage protector is that the zero sequence current is zero. When using a frequency converter, the zero sequence current cannot be zero.

The output side of the frequency converter is a PWM wave, and there is a capacitance effect of a long cable between the motor cable and the ground. When using a cable with a shielding layer, the capacitance effect is more obvious. During the operation of the frequency converter, the capacitor is being charged and discharged, and current flows into the ground through the capacitor, which then flows back to the frequency converter from the grounding wire on the incoming side, forming a current circuit. If a leakage protector is used on the incoming side, it will act and cut off the system operation.

SO, don't equip your frequency converter with a leakage protector. If you want to ensure safety, just do a good job of grounding the equipment.

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.
