B. Ground each lead one at a time at motor end and check

continuity with a meter at the drive end. This must be done to
verify drive output phase connections to ensure no leads are
swapped from slave to master. (Severe motor damage will occur
if leads are swapped.)

C. Connect leads at motor end and megger U (L1 or L11), V (L2 or

L22), W (L3 or L33) to ground.

Inverter Bridge Checks- Check the inverter bridge for grounds and
shorts.

A. Measure each incoming phase to ground.

B Measure each phase to the DC+ and DC- bridge inputs.

C. Measure DC+ and DC- bridge inputs to ground.

Jumper & Dip Switch Checks - Use the system schematics and
check the jumpers and switches on the Main Control board and
Adapter boards of both the Master and Slave drive. The FORCE User
Manual (1336T-5.12) provides in depth information on switch and
jumper settings for all adapter boards. Main Control Board Jumpers
J3 and J4 control encoder voltage selection as detailed in Figure 3.2.
