Analog setpoint values for the DE1 device via control signal terminal 4 (AI1)
will be disabled. In addition to setpoint values set via Modbus RTU, it will
also be possible to set setpoint values directly with the control signal
terminals:
• Fixed frequencies (FF1 to FF4), coded in binary with FF2
• Digitally setting the setpoint value with the UP and DOWN commands
(P-15 = 4, 5, 6).
￫
If P-13 = 2, 4, 5, 6, 7: Setting the setpoint value with the control
signal terminals will disable setting setpoint values via Modbus
RTU.
In addition to fixed frequency FF1, which can be activated directly, fixed
frequencies (FF1 to FF4) can be selected by using the binary-coded FF2
1
FF2 inputs.
