7.2.16 Read SERVOPACK Parameter (PRM_RD)
The PRM_RD command reads the setting of the SERVOPACK parameter with the specified parame-
ter number and parameter size. It stores the parameter number in Servo Constant Number (monitor-
ing parameter IW

36) and the setting in Servo User Constant (monitoring parameter IL

38).
( 1 ) Executing/Operating Procedure
1.
Check to see if all the following conditions are satisfied.
2.
Set OW

08 to 17 to execute the PRM_RD motion command.
The PRM_RD command will store the specified parameter number in the Servo Constant
Number (monitoring parameter IW

36) and the parameter setting in Servo User Constant
(monitoring parameter IL

38).
IW

08 will be 17 during command execution.
IB

090 will turn ON during the command processing and will turn OFF when the command
processing has been completed.
3.
Set OW

08 to 0 to execute the NOP motion command and then complete the
reading operation.
( 2 ) Holding and Aborting
