To adjust the output frequency of a frequency converter, the converter must provide a signal to change the frequency; this signal is called the frequency setpoint signal. The frequency setpoint method refers to the way the frequency converter provides this setpoint signal.
OKE frequency inverters offer various frequency setting methods, including keyboard operation, digital input port setting, analog signal setting, pulse signal setting, and communication mode setting. Each frequency setting method has its own advantages and disadvantages. Different frequency setting methods can be superimposed and switched according to functional requirements to achieve stepless speed regulation and soft start of the motor, resulting in high operating efficiency.
