4.3.3 Easy operation mode setting (easy setting mode)
A frequency inverter can be controlled alone via the parameter unit, through external signals
(switch, SPC outputs, external setpoint sources, etc.) or through a combination of external sig-
nals and inputs to the parameter unit. The choice of operation mode is done by setting param-
eter 79. (Refer to section 5.1.6.)
Setting of Pr. 79 "Operation mode selection" according to combination of the start command and
speed command can be easily made.
In the following example the parameter is set to the value "3" so that the motor is started by sig-
nals to the STF and STR terminals and the speed can be adjusted using the digital dial on the
operation panel.
