4.55 PARAMETERS OF ACCELERATION CONTROL
12700
Feedrate when overtravel occurs during linear acceleration/deceleration
before interpolation (for stored stroke check 2)
[Data type] Word
[Unit of data, valid data range]
Valid data range
Increment system Units of data
IS-A, IS-B IS-C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
When an overtravel alarm is issued during linear
acceleration/deceleration before interpolation, deceleration is
performed in advance so that the feedrate set in this parameter can be
attained at the time of issuance of the alarm (when the limit is
reached). Use of this parameter reduces the amount of overrun that
occurs when the overtravel alarm is issued.
If bit 2 (DS2) of parameter No. 1604 is set to 1, set in parameter No.
12700 the feedrate to be attained when the overtravel alarm for stored
stroke check 2 is issued.
NOTE
When bit 2 (DS2) of parameter No. 1604 is set to 1,
and parameter No. 12700 is set to 0, parameter
No. 1784 is used.
12710 Maximum cutting feedrate for each axis in HRV3 mode
[Data type] 2-word axis
[Unit of data, valid data range]
Valid data range
Increment system Units of data
IS-A, IS-B IS-C
Millimeter machine 1 mm/min 0 to 240000 0 to 100000
Inch machine 0.1 inch/min 0 to 96000 0 to 48000
Rotation axis 1 deg/min 0 to 240000 0 to 100000
This parameter sets the maximum cutting feedrate applied in HRV3
mode for each axis. For a specified axis, the cutting feedrate is
clamped at a maximum feedrate that does not allow the result of
interpolation to exceed the maximum cutting feedrate for that axis.
