Electronic Gear Function
Section 6-18
• Specifying the electronic gear combination in the PLC Interface Area, and
then using an IOWR instruction to change that value directly. (The number
of combinations is unlimited.)
Regardless of which of these methods is used, the change will go into effect
immediately.
Note
With the electronic gear function, when there is a remainder in the total when
the input pulses are multiplied by the gear ratio, it is possible to achieve highly
accurate synchronization by adding the remaining pulses to the next input
pulses. If the electronic gear ratio is changed during a synchronized opera-
tion, however, the remainder will be taken as 0 and the calculation will begin
with the new electronic gear ratio. For that reason there will be a temporary
drop in speed from that which was in effect before the gear ratio was changed.
Using CX-Motion
For details on using CX-Motion to set the electronic gear ratio, refer to the
CX-
Motion Online Help
.
Using IOWR
Use the IOWR instruction to specify the following addresses for the control
code, and set the numerator and denominator in any area. (Refer to the lad-
der programming example provided below.) The addresses are shown in
hexadecimal, with their decimal number equivalents shown underneath in
parentheses.

If the numerator is negative, operation will be in
the reverse direction.
If the numerator was negative with Unit Ver. 1.14
or earlier, the limit input for the direction opposite
from travel was monitored, but with Unit Ver. 1.15
or larger and with Units whose model number
ends in -V1, the limit input in the direction of travel
is monitored. Consider this point in system
design.
