16.2 Table of Shared Memory Area
Shared Memory Area
The settings of the startup speed and target speed, specifying the direction of home return, selecting the
type of S acceleration/deceleration should be made in the shared memory. The setting area (address)
varies depending on the axis, but the setting contents are the same.
1st. axis: 100h to 10Fh occupied. 2nd. axis: 110h to 11Fh occupied.
When the settings is out of range, an error occurs when each is started and a set value error flag goes
ON. Each setting value should be handled as the signed 32-bit data (double word).
The data in the shared memory will be cleared when the unit is turned OFF.

Note:
1. The shared memory is shared between E point control, P point control, JOG operation,
JOG positioning operation, home return, and pulser input operations. Be careful that the
shared memory is not overwritten at the same timing.
2. For the first speed of E point control and P point control, and for JOG operation, JOG positioning
operation and home return, the value set for the target speed should be larger than that set for the
startup speed.
3. “-” is read and written as needed.
4. Up to 4Mpps can be set for the Line driver and transistor driver types, but set 500kpps max. for the
transistor type.
5. Please note that the count of the feedback counter will be cleared when the home return is completed
or when the Error clear flag (Y_F) is ON.
