Multi-Function Digital Input Setting Values - YASKAWA GA800 Programming Manual

Note:
• Refer to H1-xx "MFDI setting values" for the setting values of the MFDI.
• You cannot set 0 [3-Wire Sequence] or 20 to 2F [External fault] in H1-40 to H1-42.
• When you will not use H1-40 to H1-42, set them to F [Through Mode].
• You cannot use MFDI for digital input option D1-A3 at the same time as function selection for MEMOBUS/Modbus MFDI 1 to 3.

0: 3-Wire Sequence
Setting Value Function
0 3-Wire Sequence
If the 3-wire sequence is set to a terminal that is not MFDI terminals S1 and S2, these terminals will be the input
terminals for Forward run/Reverse run command. The drive will automatically set terminal S1 to Run command
(RUN) and terminal S2 to Stop command (STOP).
When terminal S1 (Run command) activates for 1 ms minimum, the drive rotates the motor. When terminal S2 (Stop
command) deactivates, the drive stops. When terminal Sx that is set in 3-wire sequence deactivates, the drive operates
in the forward direction, and when it activates, the drive operates in the reverse direction.
WARNING! Sudden Movement Hazard. Set the MFDI parameters before you close control circuit switches. Incorrect Run/Stop
circuit sequence settings can cause serious injury or death from moving equipment.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] and make sure that b1-17 = 0 [Run Command at Power Up = Disregard Existing RUN Command] (default). If you do
not correctly set the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in reverse
when you energize the drive.
