Commissioning the Drive Chapter 4
DC/DC Converter (PS2)
The DC/DC converter has no provision for output power adjustments. A green
LED on front case of the power supply indicates that the power supply is
functioning properly. Using a Digital Multimeter, measure each of the outputs of
the DC/DC converter to ensure that they meet the values specified on the
electrical schematics. Compare these measured values to those displayed on the
Operator Terminal under the Metering group.
Record all plug values on the relevant Commissioning Guide data sheet.
If any values are out of the expected range, a bad DC/DC converter is suspect.
For additional information on how to troubleshoot the DC/DC converter, refer
to the troubleshooting section, Chapter 3 of the Technical Data manual,
