This section defines the APOGEE FLN points that read and write drive parameters.
u
Reading a Drive Parameter
Two points are defined for reading any drive parameter:
• #70 Specifies the parameter to be read from
• #71 Reports the value of the parameter specified in Point #70
When this point is read, it retrieves data from the parameter and sends it to the controller
Example: Writing a value of 387 (183H) to Point #70 specifies drive parameter b1-04. Reading Point #71 returns the current
setting of parameter b1-04 to the controller.
u
Writing to a Drive Parameter
Two points are defined for writing to any drive parameter:
• #72 Specifies the parameter to be written to
• #73 Entry location of the value to be written to the parameter specified in Point #72
When this point is written to, it will write the value to the drive. An enter or accept command does not need to be sent for the
data to be taken by the drive. The behavior of the write is the same as with the HOA keypad. If the drive is running, there are
a limited number of drive parameters that can be written to.
Example: Writing a value of 387 (183H) to Point #72 specifies drive parameter b1-04. Writing a value of 1 to Point #73 enables
the drive for reverse run.
