The following checks must be made:
1. Linear motor in general
– Which linear motor is being used?
– Is the motor listed?
If yes Type: 1FN_ _ _ _ –_ _ _ _ _–_ _ _ _
If no Find out the manufacturer's data for the "unlisted" linear
motor and enter
– Is the cooling circuit operational and is the coolant mixture correct? (Rec-
ommended mix: 75% water, 25% Tyfocor).
2. Mechanical components
– Can the axis move freely over the entire traversing range?
– Do the mounting dimensions of the motor and the air gap between the
primary and secondary parts comply with the manufacturer's specifica-
tions?
– Vertical axis:
If the axis has weight compensation, is this functional?
– Brake:
If a brake is fitted, is it being applied and released correctly?
– Traversing range limitation:
Are mechanical limit stops installed on both sides of the travel path and
bolted securely in position?
– Are the moving cables installed properly in a cable trailing device?
