The limits section is where parameters are defined as a safety function for the entire system, not just the motor. on Monday, September 16, 2019 If there is only one encoder, and it is mounted to the load (main encoder), then there is only the option to select block commutation. If there is a gearhead on the front of the motor for maximum accuracy it is important to configure the gearbox as an absolute ratio rather than a x:1 format as this has been simplified. The EPOS4 Hardware Reference for the relevant EPOS4 has information on the specification of the feedback sensor connectors which the sensors must conform to, such as power requirements and the EPOS4 Firmware Specification has information on the data of the sensors, such as SSI Data Rate, number of data bits and other limitations. Dual-loop is typically used when high positional accuracy is required. Therefore, as a principal regulation structure, EPOS4 offers current-based control. As the number of pole pair increases, the maximum speed decreases at the same rate, to calculate divide the max speed (based on which method of commutation you use) by the number of pole pairs to calculate the maximum speed for your motor.
