22Table 6 — Powerflex 755 Fault Code Descriptions and Corrective Actions (cont)Checking Power Modules and Motor Inputwith Input Power Off — Use the following procedureto check the drive’s power module circuitry with power off:1. Turn off and lock out input power. Wait five minutes.2. Verify there is no voltage at the drive’s input power termi-nals.3. Using a voltmeter, check the DC bus potential as de-scribed above to ensure the DC bus capacitors are dis-charged.4. Disconnect the motor from the drive.5. Check all AC line and DC bus fuses.6. Use a multimeter to check the input diodes and outputIGBTs if a fuse is open.7. Check motor impedance.8. Reconnect the motor to the drive.9. Reapply input power. See Tables 7 and 8.Table 7 — Diode ChecksNOTE: Digital meters require a special diode check functionbecause the current sourced by the meter during a normal resis-tance (Ohms) test is too low to accurately test a diode. Make surethe meter is set to the diode test function. Voltage readings may notbe exact as shown in above tables, but look for consistency duringeach of the 4 tests. When performing a test that should return infinity(OL) as shown in above tables, you may see a value slowly climbingtoward infinity. This is a result of the meter charging a capacitor andis normal.VFDFAULTCODEON VFDHISTSCREENICVCFAULTSTATEFAULT TYPE DESCRIPTION CORRECTIVE ACTION168 206 HeatSinkUnder-TmpHeatsink temperature sensor is reporting a valuebelow -18.7 C (-1.66 F) or the sensor feedbackcircuit is open.Check heat sink temperature sensor.
