2.4 The E-Gear of the Master Axis
E-gear ratio of the master axis will determine the pulse resolution, which is defined by P5-83 and
P5-84. When the slave axis receives the pulse number P from the master axis specified by P5-84,
E-Cam will rotate M circle specified by P5-83, which is M cycle of the E-Cam table. For example,
when P5-84 = 10000 and P5-83 = 1, it means when slave axis receives 10000 pulses from the
master, E-Cam travels from 0° to 360°, which is one cycle of the E-Cam table.
In Figure 2.17, If the E-gear ratio of the master is taking 10000 as a standard, when this value is
higher (value of P5-84 becomes higher or value of P5-83 becomes lower), the pulse width will
become narrower thus making a higher pulse resolution of the master axis. On the other hand, if
the E-gear ratio value of the master is lower (value of P5-84 becomes lower or value of P5-83
becomes higher), the pulse width will become wider thus making a lower pulse resolution of the
master axis.
