Details of areas
Parameter area
Area where parameters, such as positioning parameters and OPR parameters,
required for positioning control are set and stored.
Monitor data area
Area where the operation status of positioning system is stored.
Control data area
Area where data for operating and controlling positioning system is set and stored.
Positioning data area (No.1 to 600)
Area where positioning data No.1 to 600 is set and stored.
Block start data area (No.7000 to 7004)
Area where information required only when carrying out block No. 7000 to 7004
high-level positioning is set and stored.
PLC CPU memo area
Area where condition judgment values required for special positioning, etc., are
set and stored.
Servo parameter area
Area where parameters, such as servo parameters, required for positioning
control on servo amplifier are set and stored.
Synchronous control area
(Note-1)
Area where parameters and control data required for synchronous control are set
and stored. Also, the operation status of synchronous control is stored.
Cam area
(Note-1)
Area where cam data, etc., are set and stored. There are cam storage area and
cam open area.
(Note-1): Refer to "MELSEC-Q/L QD77MS/QD77GF/LD77MS/LD77MH Simple Motion Module User's
Manual (Synchronous Control)" for details of synchronous control area and cam area.
