FUNCTION CODES
Chap 5
F02
Operation method
Select setting method of run command. Indicate instruction method of run/stop and rotation direction
(forward/reverse rotation) for each setting method.
F02 data
Setting method of run command
Run/stop Rotation direction command
0: Keypad operation
(Rotation direction input: Terminal block)
/ keys
“FWD”, “REV”
1: External signal (digital input)
“FWD”, “REV”
2: Keypad operation (forward rotation)
/ keys
Rotation direction command is
unnecessary
(Forward rotation operation only,
reverse rotation operation disabled)
3: Keypad operation (Reverse rotation)
/ keys
Rotation direction command is
unnecessary
(Reverse rotation operation only,
forward rotation operation disabled)
Digital input signal, “FWD”, “REV” needs to be assigned to terminals [FWD], [REV].
( Function code E98, E99 data = 98, 99)
• F02 cannot be changed when “FWD” or “REV” is ON.
•
If F02 = 1 and when assignment of terminal [FWD] or [REV] is changed from other function to “FWD
function or “REV” function, turn the terminal [FWD] and [REV] of
f in advance (motor may rotate due to
change in the setting).
■ 3-wire operation by external signal
Although external signal of “FWD” and “REV” is 2-wire operation at the initial state, by assigning “Select 3-wire
operation (HLD)”, it is possible to use as self-hold signal at 3-wire operation by using “FWD”, “REV” and “HLD”
signals. When “HLD” is ON, inverter self-holds “FWD” or “REV” signal, and the hold state can be released by OFF.
If there is no “HOLD” function assignment, “FWD” and “REV” become 2-wire operation.
Refer to Function code E01 to E05 (Data =6) to find the details of “HLD”.
As a setting method of run command, high-priority setting methods (remote/local switch (refer to Chapter 3,
Section 3.3.7), communication, etc.) are available in addition to the above mentioned settings.
