 Dynamic Brake or Chopper Connection 3

Inductor/Connection Point During power up, there can be a racing condition between the time the drive
Locations control board comes alive and verifies all input status and the time the
Chopper control board comes alive and closes its AUX contact. To correct
this condition, Rockwell recommends connecting a programmable CR4 NC
contact at TB2-16 and TB2-17 across the Brake Chopper AUX Contact to
shunt the contact until the BUS is fully charged and the logic inputs are
satisfied. See Table B for recommended programming to provide enough
time for the Chopper AUX contact to close, thus preventing AUX fault in
the drive at power up.

ATTENTION: To avoid a shock hazard, assure that all

! power to the drive has been removed before proceeding. In
addition, verify that the DC bus has discharged by
measuring across the “+DC” and “–DC” terminals of TB1
with a voltmeter. The voltage should be 0.0VDC.

Important: Two different inductors were used — use appropriate drawing

for inductor style in drive to have DB added.
