7.16.1
Maximum machining spindle speed
The following safety regulation forces to limit the spindle speed on lathes:
There is a variable, MDISL, associated with the spindle speed limits to make this routine easier. This
variable is read-write from the PLC and read-only from DNC and CNC.
Besides updated by the PLC, this variable can also be updated in the following cases:
• When programming G92 in MDI mode.
• When programming G92 in ISO code in MC or TC mode.
• In MC or TC mode, when a new speed limit is defined in the "SMAX" field.
The speed limits entered via CNC, PLC (PLCSL) and DNC (DNCSL) keep the same functionality
and priority and are not affected by the MDISL variable; in other words, the CNC also limits the
spindle speed with these variables.
Management via PLC
To comply the safety regulation, we recommend to manage from the PLC the variables associated
with speed limit as shown in the following example. It applies the following restrictions:
• A new part-program cannot be executed without previously entering the spindle speed limit.
Otherwise, an error message will be issued.
When repeating the execution of the program, the speed limit needs not be entered, it must only
be entered when executing the program for the first time.
• While executing a program, if a new limit is entered in MDI, it replaces the previous one.
• In independent MC or TC cycles it is not required to enter the SMAX because it is already defined
in each cycle.
• If the program being executed has a G92 function, the program will only be valid if the value
defined in G92 is smaller than the one programmed by MDI.
• When having two main spindles, the speed limit entered will be valid for both.
"A program will not be executed in machining mode unless the maximum spindle speed value for the
part is entered as well as the proper maximum speed for the part holding fixture for the machine.
Should the operator forget to enter or validate these speeds in each program change, the execution
in machining mode will not be possible.
It will not exceed the lower speed among the maximum by parameter, the maximum by program and
the maximum entered manually.
