Mitsubishi Electric FR-F740 EC Instruction Manual page 125

Operation
Power on → operation mode check
For the initial setting, the inverter operates in the
external operation mode "EXT" when powering
on. Check that the operation command indication
is "EXT". If not displayed, press the PU/EXT key
to change to the external "EXT" operation mode.
If the operation mode still does not change, set
Pr. 79 to "0" to change to the external operation
mode. (Refer to section 5.7.)
Turn the start signal STF or STR on. Operation
status indication FWD or REV flickers.
CAUTION:
When both the forward and reverse signal are
turned on, the inverter will not start. Also, if both
switches turn on while running, the inverter
stops.
Acceleration → constant speed
Turn the volume (frequency setting potentiometer)
clockwise slowly to full.
The frequency value on the indication increases
according to Pr. 7 "Acceleration time" until 50Hz
is displayed.
Deceleration
Turn the volume (frequency setting potentiometer)
counter clockwise slowly to full.
The frequency value of the indication decreases
according to Pr. 8 "Deceleration time" until 0.00Hz
is displayed.
The motor stops.
Stop
Turn the start switch STF or STR off.

NOTES When you want to operate in the external operation mode always at powering on or when
you want to save the trouble of input, set "2" (external operation mode) in Pr. 79 "Operation
mode selection" to choose external operation mode always.
Pr. 178 "STF terminal function selection" must be set to "60" (or Pr. 179 "STR terminal func-
tion selection" must be set to "61"). (All are initial values.)
