F02 Operation Method
F02 selects the source that specifies a run command.
Data for F02 Run Command Description
0
Keypad Enables the , , and keys to run the motor in the
forward and reverse directions, and stop the motor.
1
Terminal command
FWD
or
REV
Enables input terminal commands
FWD
and
REV
to run the
motor in the forward and reverse directions, and stop the motor.
2
Keypad
(Forward rotation) Enables the and keys to run the motor in the forward
direction and stop it. Running the motor in the reverse direction
is not possible.
3
Keypad
(Reverse rotation) Enables the and
keys to run the motor in the reverse
direction and stop it. Running the motor in the forward direction
is not possible.
• When F02 = 1, the "Run forward"
FWD
and "Run reverse"
REV
terminal commands must be assigned to
terminals [FWD] and [REV], respectively.
• When the FWD or REV is ON, the F02 data cannot be changed.
• When changing terminal command assignments to terminals [FWD] and [REV] from commands other than the
FWD
and
REV
to the
FWD
or
REV
with F02 being set to "1," be sure to turn the target terminal OFF
beforehand; otherwise, the motor may unintentionally rotate.
„ 3-wire operation with external input signals (digital input terminal commands)
The default setting of the
FWD
and
REV
are 2-wire. Assigning the terminal command
HLD
self-holds the forward
FWD
or
reverse
REV
run command, to enable 3-wire inverter operation. Short-circuiting the
HLD
-assigned terminal and [CM] (i.e.,
when
HLD
is ON) self-holds the first
FWD
or
REV
at its rising edge. Turning the
HLD
OFF releases the self-holding.
When no
HLD
is assigned, 2-wire operation involving only
FWD
and
REV
takes effect.
For details about
HLD
, refer to E01 to E07 (data = 6).
In addition to the run command sources described above, higher priority command sources including remote and local mode
(see Section 7.3.6) and communications link are provided. For details, refer to the block diagrams in Chapter 6 in
FRENIC-MEGA User's Manual.
