Variable Speed Drives (VSDs) require preventative
maintenance just like any other industrial electrical
device. There are many different manufacturers and
sellers of VSDs, but all have the same basic
maintenance needs.
Here are some recommendations that will help achieve
the longest possible service from your Sullair VSD.
6.7 COMMISSIONING YOUR VSD:
• Record all Supervisor Controller / VSD Set Up
parameters for later reference.
• Perform a close visual inspection of the internal
components of the unit, looking for obvious loose
connections (see torque spec) or hidden shipping
damage.
• Ensure the installation and pre-power checks have
been performed in accordance with the VSD Pre-
ventative Maintenance instruction manual.
• Record line voltage, full load current, operating
speed of the motor, and drive temp information for
later reference.
6.8 AFTER THE FIRST 48 HRS
OF OPERATION:
• Remove the unit from service and using all proper
safety precautions inspect for the following:
• All power connections for tightness. (See torque spec)
• Over-all visual inspection for any signs of extreme
overheating or stressed components.
6.9 EVERY SIX MONTHS
• While the VSD is operating, measure and compare
the operating temperatures to those previously
recorded from the Supervisor Controller VSD Status/
Drive Temp.
• Following all proper safety precautions, check or
perform the following:
1. Using clean dry compressed air to clean the
unit of all dust and debris.
2. Check all connectors and connections for
tightness. (See torque spec)
3. General visual inspection for visible signs of
overheating or component stress.
4. Clean and check all cooling fans for proper
operation. (See section 1-23 for the size of
VSD for your unit and procedure.)
