According to the external input signal, to set the analog signal:
0-5V, 0-10V or 4-
20mA
. Between analog signal voltage range and motor speed, there is a linear
relationship (when the working speed limit is off).
With the maximum working speed limit turned on, the motor speed will be
limited
. For example, if 0V to 0rpm, 5V to 600rpm (then 2.5V should be 300rpm).
But if the maximum working speed limit is 300rpm, when the external input analog
signal is 2.5V, the motor speed is 300rpm. After the input signal exceeds 2.5V, the
motor speed remains unchanged at 300 rpm.
