1. AXIS CONTROL
161
S Set the feedrate along each Z--axis for superimposed control in
parameter Nos. 8190z, 8191z, and 8193 of both paths. Each value
to be set must be about half the one for independent control.
S Set the rapid traverse time constant for each Z--axis under
superimposed control in parameter No. 8192z of both paths. Each
value to be set must be 1 to 2 times the one for independent control.
(3)Signal setting
S Set signal G1190#1 OVLS2 to “1” when superimposed control
begins for the Z1-- and Z2--axes.
S Reset signal G1190#1 OVLS2 to “0” when superimposed control
ends.
S Also reset G1190#1 OVLS2 to “0” when an emergency stop, NC
reset, or alarm occurs.
S Keep signals other than G1190#1 OVLS2 reset to “0”.
