Subroutine 44 - COOLING (cooling control)
Purpose
Subroutine 44 is used to start/stop cooling using the buttons on the MCP in the JOG mode, or to start (using the auxiliary
function M07/M08 in the part program) or to stop (using the M09 in the part program) cooling in the AUTO/MDA mode.
Cooling is forbidden in case of EMERGENCY STOP, cooling motor overload, program test or under the simulation mode.
This subroutine can activate the following alarms:
● Alarm 700018: motor overload for the cooling pump
● Alarm 700019: low coolant level
