Maximum angle for square corner.
The CORNER command sets the maximum angle between two paths (between 0º and 180º),
under which the CNC machines in square corner mode. Programming it is optional; if not
programed, the CNC assumes the angle set in machine parameter CORNER.
Maximum error on rotary axes.
The RE command defines the error in all the rotary axes and linear axes (except the first
three axes of the channel). Programming it is optional; if not programmed, the CNC assumes
as maximum error the highest value between machine parameter MAXERROR and the E
command.
Path filter frequency for linear slope.
The SF command allows applying different filters to those set in the machine parameters.
Programming it is optional; if not programmed, the CNC assumes as frequency of the filter
the one defined in machine parameter SOFTFREQ.
Axis filter frequency in HSC mode.
The AXF command allows applying different filters to those set in the machine parameters.
Programming it is optional; if not programmed, the CNC assumes as maximum contouring
error the value set in machine parameter FASTFILTFREQ.
Considerations.
Percentage of acceleration in the transition between blocks.
The percentage of acceleration in the transition between blocks may be modified using
functions G130/G131. The CNC assumes by default the value of machine parameter
ACCEL.
Commands E and CORNER.
The CNC maintains the value of the commands programmed until a different one is
programmed, the HSC mode is canceled, a reset is done or the program ends.
When switching HSC modes, the CNC keeps the values programmed in the previous mode
for the commands that are not programmed (for example, the contouring error). If no HSC
mode has been programmed earlier, the CNC takes the default values for the commands
that are not programmed.
Commands RE, SF and AXF.
The CNC maintains the value of the commands programmed until a different one is
programmed, the HSC mode is changed or canceled, a reset is done or the program ends.
When changing HSC modes, the CNC assumes the default values set in the machine
parameters.
Execute an HSC mode starting with initial conditions.
To execute in HSC mode starting with initial conditions, first cancel the previous mode. See
"20.6 Canceling the HSC mode." on page 374.
From versions V1.30 (8060) and V5.30 (8065/8070), the #HSC instruction does not let program the
percentage of acceleration for transition between blocks.
