PRE-OPERATION INSTRUCTIONS
Terminal name
Turn ON the STF signal to
Forward rotation
start forward rotation and
start
turn it OFF to stop.
Turn ON the STR signal to
Reverse rotation
start reverse rotation and
start
turn it OFF to stop.
Multi-speed Multi-speed can be selected according to the
selection combination of RH, RM and RL signals.
Turn ON the MRS signal (2 ms or more) to stop the
inverter output.
Output stop
Use this signal to shut off the inverter output when
stopping the motor with an electromagnetic brake.
Use this signal to reset a fault output provided when a
protective function is activated. Turn ON the RES signal
for 0.1 second or more, then turn it OFF.
In the initial setting, reset is always enabled. By setting
Reset Pr.75, reset can be enabled only at an inverter fault
occurrence. The inverter recovers about 1 second after
the reset is released.
(For details of Pr.75, refer to the FR-E800 Instruction
Manual (Function).)
