2.6 Machine parameters for the axes. Work sets.
Up to 4 different parameter sets may be defined to indicate the dynamics of the axis in each
one of them (feedrates, gains, accelerations, etc.). Each set only shows the parameters for
the selected type of axis and drive.
In the laser model, the parameters related to spindle speed (defined in rpm) define the power
(defined in watts).
2.6.1 Feedback resolution.
PITCH
Leadscrew pitch.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): From 0 to 99999.9999 mm.
Possible values (2): From 0 to 3937.00787 inch.
Possible values (3): From 0 to 99999.9999 degrees.
Default value: 5 mm / 0.19685 inch / 360º.
Associated variable: (V.)[ch].MPA.PITCH[set].xn
The meaning of this parameter depends on the type of feedback.
• On a linear axis with a rotary encoder and leadscrew, the parameter defines the
leadscrew pitch.
• On a linear axis with a linear encoder (scale), the parameter defines the pitch of the scale.
• On a rotary axis, the parameter sets the number of degrees per turn of the encoder.
INPUTREV
Turns of the motor shaft.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 1 to 32767.
Default value: 1.
Associated variable: (V.)[ch].MPA.INPUTREV[set].xn
See machine parameter OUTPUTREV.
OUTPUTREV
Turns of machine axis.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 1 to 32767.
Default value: 1.
Associated variable: (V.)[ch].MPA.OUTPUTREV[set].xn
The possible gear ratio between the motor and the encoder may also be entered directly
through parameter PITCH; in that case, parameters INPUTREV and OUTPUTREV must be
set to ·1· If the gear ratio is not an integer multiple, we recomend to set the real values of
the gear ratio in INPUTREV and OUTPUTREV instead of leaving a inaccurate number in
PITCH.
Type of axis. PITCH
