Parameter
Function Settings
MC_2971:
Gear change RPM
Spindle gear change RPM specifies the
spindle speed at which a gear change is
performed.
Range (0–50)
10 (rev/min) [Default]
MC_2972:
Gear ranges used
To set up for only one gear range, set to
Single-M40 [Default]. To set up for
multiple gear ranges, select
Multiple
.
Single-M40
[Default]
Multiple
MC_2973:
RPM Display
Spindle RPM Display allows you to
configure the CNC to display feedback
from a spindle encoder (Feedback) or
from a programmed RPM.
NOTE:
This parameter affects only the
displayed RPM value. It does not affect
RPM or voltage output to the spindle.
Feedback
[Default]
Program
MC_2974:
Check spindle during
gear change
Checking the spindle during gear
change allows you to either stop the
spindle before you can change a gear
(for example, change from M41 to M42)
or enables you to change gears without
stopping the spindle.
No
Yes
[Default]
If this parameter is set to
Yes
and
a gear change code is executed
with the spindle running, the CNC
will generate an error message. If
parameter is set to
No
, a gear
change code may be executed with
the spindle running.
MC_2975:
Stop program on gear
change
Stopping the program on gear change
allows you to configure the CNC to stop
program execution during a gear
change.
No
[Default]
Yes
If you specify
Yes
, the CNC checks
for spindle movement (RPM). If
there is spindle movement, the
CNC displays an error message
and stops the machine. If you
specify
No
, the CNC does not stop
the machine for a gear change.
MC_2976:
Check RPM to be
within gear range
Checking RPM to be Within Gear
Range
prevents you from designating a
RPM outside the active gear range.
No
Yes
[Default]
If you specify
Yes
, the CNC checks
the RPM. If the entered RPM is
not within the active gear range,
the CNC displays an error
message. If you specify
No
, the
CNC does not check the entered
RPM against the active gear range.
