Connection macro Cn005 - Analog input and fixed frequency
The analog input works as an additional setpoint.
If digital input 2 and digital input 3 are active together, the selected frequencies are summed,
that is, FF1 + FF2.
Function diagram
When the fixed speed is selected, the additional setpoint channel from the analog is
disabled. If there is no fixed speed setpoint, the setpoint channel connects to the analog
input.
