fraction indicated by the settings. For example, you may set 16 for
parameter No. 7772 and 108 for parameter No. 7773 for this example.
7782 Number of pulses from the position detector per EGB master axis rotation
[Input type] Parameter input
[Data type] 2-word axis
[Valid data range] 1 to 999999999
This parameter sets the number of pulses from the position detector
per EGB master axis rotation.
For an A/B phase detector, set this parameter with four pulses
equaling one A/B phase cycle.
7783 Number of pulses from the position detector per EGB slave axis rotation
[Input type] Parameter input
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] 0 to 999999999
This parameter sets the number of pulses from the position detector
per EGB slave axis rotation.
Set the number of pulses output by the detection unit.
Set this parameter when using the G81.5 EGB synchronization
command.
The method for setting parameters Nos. 7782 and 7783 is the same as
for parameters Nos. 7772 and 7773. For the method, see the
description of parameters Nos. 7772 and 7773.
The ratio of the number of pulses for the master slave to that of pulses
for the slave axis may be valid, but the settings of the parameters may
not indicate the actual number of pulses. For example, the number of
pulses may not be able to be divided without a remainder for the
reason of the master and slave axis gear ratios as described in example
2. In this case, the following methods cannot be used for the G81.5
command:
G81.5 T_ C_ ;
When the speed is specified for the master axis and the travel
distance is specified for the slave axis
G81.5 P_ C0 L_ ;
When the number of pulses is specified for the master axis and
the speed is specified for the slave axis
