Operation Mode - Mitsubishi Electric Freqrol-A100 Instruction Manual

2.1.3
Operation Mode
The inverter has three operation modes: "operation using the external input
signals" (external operation mode), "operation using the PU" (PU operation
mode), and "combined operation using the external input signals and PUN
(combined operation mode).
Factory-set operation mode
When the input power is switched on (or
the inverter is reset), the inverter is set
to the mode of "operation using the ex-
ternal input signals". Therefore, as soon
as the input power is switched on, the
inverter is ready for operation using the
external input signals. In this state, turn
the start signal (across STF, STR and
SD) on to start operation.
