Important: You must align J4 Pin 1 with J4B Pin 1. J4 has
eleven pins and J4B has twelve pins. If you fail to
align the connectors, the 120L4060 drive will not
run because motor voltage feedback circuits will
remain open. The LF151200W4 drive does not use
motor voltage feedback, so there is no electrical
connection between J4 and J4B.
