7.6.1 Cleaning Instructions
When necessary to clean the servo drive, follow the directions below:
Ventilation system:
Disconnect the control and power supply of the servo drive and wait for 10 minutes.
Remove de dust accumulated on the ventilation openings using a plastic brush or cloth.
Remove the dust accumulated on the fins of the heatsink and fan blades using compressed air.
Electronic card:
Disconnect the control and power supply of the servo drive and wait for 10 minutes.
Remove the dust accumulated on the cards using and anti-static brush or ion compressed air gun (Example:
Charges Burtes Ion Gun (non nuclear) reference A6030-6DESCO).
If necessary, remove the cards from the servo drive.
Always use grounding strap.
