Rockwell Automation 1560E SMC Flex Smart Motor Controller - Manual (Page 76)

Power Supply Tests (cont.)
NOTE: Systems with optional Pump Control or Soft Stop include
continuous gate drive power supplies (IGDPS); therefore, step 5 does not
apply.
5. Since the gate driver circuits normally receive power from the snubber
circuits when the SMC is operating, an alternate source must be used
for testing. Locate the Portable Test Power Supply that was included
with the equipment, and verify that the rating corresponds to the
available power system (i.e. 110/120 VAC or 220/240 VAC). Plug the
unit into the power source, and plug the green connector into TB1 on
each of the gate driver sections (See Figure 3.4).

6. The yellow LED on the upper right-hand side of the energized gate
driver circuit should be lit (it may appear dim, depending on ambient
light conditions). This is normally sufficient to verify that the gate drive
system is functioning, however, a more detailed check can be made
utilizing steps 7 and 8.
