Spindle Axis Load Meter
When a SERVOPACK is used for the spindle axis (i.e., when Pn01E.0 is set to 1 or 5), use a load meter to
determine how much of the capacity of the spindle axis is being used.
The load meter can be used to set the base spindle motor output with a parameter setting.
Set the load meter base setting, for example, to operate the spindle axis for a short period of time only to per-
form cutting or to perform continuous cutting with the spindle axis, based on the customer’s needs.
Determine how to display the information from the spindle axis load meter on the host controller GUI so that
it is easy to view, whether it be as numerical data or in the form of a bar graph or as a traditional needle-type
display.
You can apply a filter at the SERVOPACK due to the rapid value changes that occur in short intervals from the
load meter monitor.
9.6.1
Load Meter Monitor Selection
To monitor the load meter, select either Optional Monitor 1 or Optional Monitor 2 for the monitor selection
and then select the load meter for parameter Pn824 or Pn825.
For details, refer to
9.1 SERVOPACK Monitors
.
Setting Example to Monitor the Load Meter with SEL_MON3
SVCMD_CTRL.SEL_MON3 = 0E hex (Selects Optional Monitor 1.)
Pn824 = 3E hex (Selects the load meter.)
9.6.2
Load Meter Base Selection
A parameter is set to select where the base setting of the load meter must be, based on the output characteris-
tics of the spindle motor.
Note: When a motor for winding selection (UAKBJ-
C) is used, the load meter base setting changes based on the out-
put characteristics when low-speed or high-speed winding is selected.
The SERVOPACK software must be version 000A or higher to use the load meter.
