Operation; Instruments And Parts To Be Prepared Before Operation - Mitsubishi Electric Freqrol-A100 Instruction Manual

2.1 OPERATION
/ ; ; h e FR-A1OOE inverter can be operated in any of three modes. Select the
appropriate mode for an application and running conditions and prepare
required instruments and parts.
Note: This inverter is desiged for use with the
F R - P U 0 2 - 1
or
F R - A R W E - 1
parameter units. If a previous type of parameter unit is used the inverter
will not start in external or communication mode as Pr. 75 is factory set
to
" 1 4 " .
Like wise if a previous parameter unit (not
F R - P U 0 2 E - 1
or FR-ARWE-I)
is connected during inverter operation, the inverter will be decelerated
to a stop. (Refer to page 100.)

operation mode
The inverter is operated with the external operation and PU
operation
modes combined in either of the following two
methods.

Use this cable when the parame-
ter unit is held in hand to perform
operation, for example.
1)
The external signal is used as the start signal and the
PU is used to set the frequency.

"PU" stands for the parameter unit.
2)
The operation command key of the PU is used to start
and the external frequency setting potentiometer is
used to set the frequency.
