3. Instruction Set<br />

6. Please use NO contact as the drive contact of DABSR instruction. If the drive contact is OFF<br />

during the execution of DABSR, the instruction will be stopped and errors will occur on read<br />

data.<br />

7. If the drive contact of DABSR instruction turns OFF after the instruction is completed, the<br />

servo ON (SON) signal connected to D 1 will also turn OFF and the operation will be disabled.<br />

8. Flags: For the descriptions of M1010, M1029, M1102, M1103, M1334, M1335, M1336, M1337,<br />

M1346, please refer to Points to Note.<br />

Program Example:<br />

1. When X7 = ON, the 32-bit absolute position data read from servo will be stored in the registers<br />

storing present value of CH0 pulse output (D1348, D1349). At the same time, timer T10 is<br />

enabled and starts to count for 5 seconds. If the instruction is not completed within 5 seconds,<br />

M10 will be ON, indicating operation errors.<br />

2. When enabling the connection to the system, please synchronize the power input of <strong>DVP</strong>-PLC<br />

and SERVO AMP or activate the power of SERVO AMP earlier than <strong>DVP</strong>-PLC.<br />
