• User
: Data before the execution of dedicated instructions is stored by user.
• System: Data after the execution of dedicated instruction is stored by PLC CPU.
2: Refer to Section 15.2 for error codes at abnormal completion.
[Functions]
(1) The positioning data is read from the servo amplifier capable of processing the
absolute positions of the axes to be set (See below), and the values converted with
respect to a unit are stored in "
Md.20
current feed value" and "
Md.21
machine
feed value" area of the QD75.
• ABRST1: Axis 1
• ABRST2: Axis 2
• ABRST3: Axis 3
• ABRST4: Axis 4
For absolute position detection system, carry out the absolute position restoration
operation each time the power is turned ON or PLC CPU is reset.
