MPGNPUL (P82)
Parameter MPGNPUL (P82) indicates the number of pulses per turn of the electronic handwheel.
Example
Having a Fagor electronic handwheel (25 pulses per turn) we would like to move 1 mm per
handwheel turn.
1. Set the a.m.p. for the feedback input of the electronic handwheel AXIS1 (P0) through AXIS7 (P6),
to a value of 12 (Fagor 100P handwheel). Also set g.m.p. MPGAXIS (P76) to indicate which axis
has been assigned this handwheel.
2. Set parameter MPGNPUL=25 or 0 meaning 25 pulses per turn of the Fagor handwheel.
3. Since the handwheel outputs square signals and the CNC applies a x4 multiplying factor to them,
we get 100 pulses per turn.
4. The value to be assigned to parameter MPGRES depends on the axis resolution format.
With 5.3mm type display format, set MPGRES=1
With 4.4mm type display format, set MPGRES=2
With 6.2mm type display format, set MPGRES=0
