3) connect the DGFC to the DeviceNet network, power off and then on the system
ATTENTION: maximum number of parameters read is 10
ATTENTION: maximum number of parameters written is 10
ATTENTION: before starting be sure that the number of parameters received and transmitted matches
on the DGFC and master. Otherwise unpredictable behavior can occur.
3.2.1. Example
Note: Remember that at the number of the drive parameter must be sum of the parameter number +2000Hex
(8192 decimal). For example, the number that you must use for T current ref 1 (torque set point has parameter
number 39) is 8231 decimal (8192 + 39) or in hexadecimal 202711 (2000H +2711). During Internal-to-External
(TE) communication the parameter is exchanged from the DGFC to the drive and during External-to-Internal
(El) communication from the drive to the DGFC. SYN (synchronous parameter) is used for high priority param-
eter of the drive, and ASYN for those parameters identified with the symbol
*
in the drive parameter tables.

(Ramp ref 1 parameter number 44)
(Pad 0 parameter number 503)
(Enable drive parameter number 314)
(Start/stop parameter number 315)
(Control word parameter number 55)
(T current lim+ parameter number 8)
(T current lim- parameter number 9)
(Enc 1 position parameter number 197)
(Actual Speed parameter number 122)
(Ramp outp [rpm] parameter number 113)
(Ramp ref [rpm]parameternumber 110)
(Status Word parameter number 56)
(Drive ready parameter number 380)
This means that:
-
the PLC will transmit 5 words (iQ bytes) to the drive in the following order and manner:
-
word 0 is synchronous parameter 8230 of the drive
-
word 1 is synchronous parameter 8695 of the drive
-
word 2 is asynchronous parameter 8506 of the drive
-
word 3 is asynchronous parameter 8507 of the drive
-
word 4 is asynchronous parameter 8247 of the drive
