Starting Operation
Section 2-2
The set values for Pn50B and Pn511 are written in the same way, i.e., by
changing the details of the Servo Parameters to be transferred and turning
ON the WRITE DATA Bit.
Writing the Pn50B Set Value
Writing the Pn511 Setting
The following diagram shows the operation used to transfer parameters to the
Servo Drive.
Word Set value Parameter transfer
setting
Details
CIO 117 050B hex Servo Parameter No. Write Servo Parameter No.:
Pn50B
CIO 118 0002 hex Parameter size Write parameter size: 2 (bytes)
CIO 119 8883 hex Write data (rightmost
word) Write Servo Parameter setting:
8883
CIO 120 --- Write data (leftmost
word) Parameter size is two bytes (one
word, so this is not used.) The set-
ting is ignored.
Word Set value Parameter transfer

word) Write Servo Parameter setting:
6541
CIO 120 --- Write data (leftmost
