Checking the reference values
After the successful completion of reference machining, check the
determined reference values.
The load monitoring function compares current
utilization values with limit values. For proper
comparison, the reference values for utilization must
not be too low. Check the determined values and, if
required, remove monitored axes with a utilization rate
of less than 5 % from the monitoring zone.
Meanings of the values:
Utilization: Determined drive torque relative to the rated torque
of the drive in [%]
Utilization sum: Sum of the utilization values in the monitoring
zone in [%*ms]
Opening the reference values:
Select the Display menu item
Select the Edit load data menu item
The control opens the Set load data form
containing the parameters listed below. In
addition, the determined values are displayed as
a bar graph
Cycle parameters:
ZO: Zone number – Number of the monitoring zone
AX: Axis name – Monitored axis
CH: Channel no. – Selected channel
T: Tool pocket of the active tool in the monitoring zone
ID: ID no. – Name of the active tool in the monitoring zone
P: Utilization – Maximum utilization during reference machining
PA: Utilization – Maximum utilization during the current
machining operation
PG1: Limit value – Utilization limit 1
PG2: Limit value – Utilization limit 2
W: Utilization sum during reference machining
WA: Utilization sum during the current machining operation
WGF: Limit value factor – Factor for the limit of the utilization
sum
