If Reverse Motor Phase Sequence (B26) = 0 the output phase sequence is U-V-W when Output Frequency (J60) is positive and W-V-U when Output
Frequency (J60) is negative. If Reverse Motor Phase Sequence (B26) = 1 the output phase sequence is reversed so that the phase sequence in W-
V-U for positive frequencies and U-V-W for negative frequencies.
Fast Disable (B27) normally shows the hardware enable state based on the state of the safe torque off system. However, drive I/O can be routed to
Fast Disable (B27) to reduce the disable time. See description of the enable logic for more details.
