Step 2 – Conn24VDC Power
You must connect an ex24VDC power source to the Gem6K, as the next
drawing shows. Use the removable terminal connector that is supplied with the
drive.
With +24VDC applied, the drive’s internal control board will remain powered
when the primary AC power source is disconnected, and will maintain several
important functions, including communication diagnostics, position feedback, and
other logic functions.
