Function description
The inverter can now be started via input 1 (forward run) or input 2 (reverse run). If
the inputs RV and FW are both closed, the inverter is stopped.
By adjusting the external potentiometer the desired frequency set value (voltage set
value) can be set.
The analog meter can be used to display the frequency (parameter 00 must be set
under C 23) or the motor current (parameter 01 must be set under C 23). With
function b 81 the displayed frequency or current value can be adjusted to the
measuring range of the special meter used.
