installation, roll pressure & release, Pilot release Installation The Rapid-Air servo was run and fully tested before being shipped from our plant. Carefully inspect all parts when uncrating them. If you find any damaged parts, please report it to the carrier that delivered the servo drive and at the same time, report the damage to your distributor. 1) console stand – optional 1) servo mounting bracket – optional 1) cascade roller assembly – optional mounted on the bracket.
feed rolls, pilot release stop, entrance guide Feed Rolls Pilot Release Stop The rolls are case hardened and ground solid rolls which make them good for profiling, if you are running a part that would need clearances ground into the roll. Useful information that you might need in the future is that one revolution of the rolls is 3.173 inches. This can be used to check if the program and motor are working correctly. Put a line on the lower roll and program the feed to feed to feed 3.173 inches.
Operator input section Operator Input Section The intent of this section is to familiarize the operator with the flow of the program and what to expect with each key press. Each program screen of the servo will be displayed and also comments to clarify possible questions.
