Regenerative Drives — Reversing and Non-Regenerative Motor Applications
Wiring Specifications Terminal Blocks J5 and J6 are available for either regenerative or
non-regenerative drive connection.
Note: Only regenerative drives allow motor reversing. Regenerative
drives require that quadrature pulse encoders be used.
ATTENTION: The incorrect wiring of the pulse encoder
and/or motor can cause an overspeed condition. Verify
correct motor and pulse encoder polarity in the Start-Up and
Adjustment section of the 1397 User Manual. Failure to
observe this precaution could result in bodily injury.
