12.7 H: TERMINALS
692 SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
Note:
• Turning ON the Forward Run command terminal and the Reverse Run command terminal will cause alarm EF [FWD/REV Run
Command Input Error] and the motor will ramp to stop.
• Initialize the drive with a 2-wire sequence to set the Reverse Run command to terminal DI2.
• This function will not operate at the same time as H1-xx = 3, 4 [Run Command, FWD/REV Cmd].
■ 3: Run Command
Setting Function Description
3 Run Command
Sets the Run command for 2-wire sequence 2. Set this function and H1-xx = 4 [FWD/REV Cmd] together.
ON : Run
OFF : Stop
Note:
This function will not operate at the same time as H1-xx = 1, 2 [Forward Run, Reverse Run].
■ 4: FWD/REV Cmd
Setting Function Description
4 FWD/REV Cmd
Sets the direction of motor rotation for 2-wire sequence 2. Set this function and H1-xx = 3 [Run Command] together.
ON : Reverse
OFF : Forward
Note:
• You must input the Run command to rotate the motor.
• This function will not operate at the same time as H1-xx = 1, 2 [Forward Run, Reverse Run].
■ 5: 3-Wire Seq.
Setting Function Description
5 3-Wire Seq.
Sets the direction of motor rotation for 3-wire sequence.
If the 3-wire sequence is set to a terminal that is not MFDI terminals DI1 and DI2, these terminals will be the
input terminals for Forward run/Reverse run command.
The drive will automatically set terminal DI1 to Run command (RUN) and terminal DI2 to Stop command
(STOP). When terminal DI1 (Run command) activates for 1 ms minimum, the drive rotates the motor. When
terminal DI2 (Stop command) deactivates, the drive stops. When terminal DIx 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 terminal parameters before you close the control circuit wiring. Incorrect
Run/Stop circuit sequence settings can cause death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard.
When using a 3-Wire sequence:
• Set the drive for 3-Wire sequence.
• Set b1-17 = 1 [RUN@PowerUp Selection = Disregard RUN]
• Wire the drive for 3-Wire sequence.
If these three conditions are correct, the motor can rotate in reverse when energizing the drive:
• The drive is wired for 3-Wire sequence.
• The drive is set for a 2-Wire sequence (default).
• b1-17 = 2 [Accept RUN]
Failure to obey can cause death or serious injury from moving equipment.
