SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 671
■ 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.

Figure 12.74 3-Wire Sequence Time Chart
Note:
• To input the Run command, activate the terminal for 1 ms minimum.
• The default setting for b1-17 [RUN@PowerUp Selection] is 1 [Disregard RUN]. If you enable the Run command when the drive is
energized, the protective function will activate and the will flash quickly. If Run is permitted in the application, set b1-17 = 2
[Accept RUN].
■ 6: Jog Reference
Setting Function Description
6 Jog Reference
Sets the drive to use the JOG Frequency Reference (JOG command) set in d1-17. The JOG Frequency Reference (JOG
command) overrides Frequency References 1 to 16 (d1-01 to d1-16).
