These Position Control Units are CJ-series Special I/O Units. The Units
receive instructions from the Programming Controller's Work Area and output
pulse trains to various motor drivers for positioning.
The Position Control Unit (PCU) responds to instructions from the CPU Unit
within 2 ms. (For more details on the conditions required, refer to Appendix A
Performance Characteristics.)
There are two different control methods. The first is memory operation, in
which the data required for positioning is transferred to the PCU and then
specified for position control, and the second is direct operation, in which the
target position and target speed are set each time from the CPU Unit.
The PCU is available with 1, 2, or 4 control axes. With 2-axis and 4-axis mod-
els, linear interpolation is possible for all axes. Either open collector output or
line driver output is available for any number of control axes. Choose the most
appropriate model according to the number of controlled axes and the desired
output type.
A stepping motor driver and a pulse train input type Servo Drive can be con-
nected to the PCU. It is possible to set different operating modes for different
axes allowing the combined use of different types of motor driver.
When an interrupt is input during pulse output, positioning is continued for
only a specified amount and then stopped.
Positioning can be performed for positions in the range –1,073,741,823 to
1,073,741,823 pulses and speeds in the range 1 to 500,000 pps in 1-pulse
units. This means that positioning is possible over a wide range with speed
precision.
