Note
In the wiring examples for modes 1 to 3, the servomotor driver used is an
OMRON R88D Servomotor Driver. Set the servomotor driver so that the servo-
motor driver’s positioning completed signal is OFF during motor operation and
ON while the motor is stopped. If this setting is not made, positioning may
become impossible without the positioning completed signal in the operating
memory area turning ON.

Operating Memory Area
The operating memory area is allocated to the Programmable Controller’s IR
area. The IR area addresses are determined when the Position Control Unit’s
unit number is set.
The operating memory area is divided into outputs and inputs. Commands
related to operations are allocated to the output memory area, and the com-
mands are sent to the Position Control Unit (PCU) when their respective bits are
turned ON, or at the rising edge (
↑
) when the bits are turned ON.
The PCU’s status and present position are input from the PCU to the input area.
The operating data area exchanges data with the PCU with every I/O refresh, so
operating commands and so on can be executed simply by writing to the Pro-
grammable Controller’s IR area.
Note
If the CCW limit setting is equal to or greater than the CW limit setting in the axis
parameters area, and if the software limits are disabled, the present position will
be “0” when memory operation or direct operation is started.
