The usage of pulses for setting controls and signal blocks is widely used in PLCs, for a wide range of tasks. Even though, most frequency converters do not count on this resource to receive setpoint from PLCs, this is usually done through analog inputs/outputs or Fieldbus. Delta C2000 has a fast signal receiving digital input, called MI8 high speed input, through this digital input C2000 can receive a setpoint: speed or position. Another advantage is that PLCs usually have few analog outputs built-in, which can be expanded by AI/AO cards. However, with Delta DVP28SV you can assign until 4 channels in order to control external devices such as Delta C2000 drives, through its internal PLCs to set speed and also position from a train of pulses. The MI8 high speed input can count until 33Khz. On this note, we are going to learn how to set this MI8 to work in speed control and in position control.
