Cn003 - Fixed speeds
Three fixed speeds with ON/OFF
If several digital inputs are active at the same time, the
selected frequencies are summed, for example, FF1 + FF2
+ FF3.
Cn005 - Analog input and fixed frequency
The analog input works as an additional setpoint.
If digital input 2 and digit input 3 are active together, the
selected frequencies are summed, that is, FF1 + FF2.
Cn007 - External push buttons with analog control
Note that the command sources are pulse signals.

Up to 16 different fixed frequency values (0 Hz, P1001 ...
P1015) can be selected by the fixed frequency selectors
(P1020 ... P1023).
Cn006 - External push button control
Note that the command sources are pulse signals.
Cn008 - PID control with analog reference
If a negative setpoint for the PID control is desired, change
the setpoint and feedback wiring as needed.
