Subroutine 45 - LUBRICAT (control of lubricate)

Purpose
Subroutine 45 is used to control the lubrication according to specific time interval and duration (independent of the distance
that the axis has travelled). Meanwhile, a manual button is available to start the lubrication, and you can configure that the
lubrication starts automatically each time that the machine is powered up. Normally, lubricating starts automatically and
cyclically according to specified time interval Lintv, and operates for a specific time Ltime at each cycle. Lubrication stops in
case of an Emergency Stop, lubrication motor overload, low lubricant level.
This subroutine can activate following alarms:
● Alarm 700020: lubrication motor overload
● Alarm 700021: low lubricant level
