Information about the parameter response:
● Request reference mirrored:
This response belongs to the request with request reference 25.
● Response identifier:
01 hex → Read request positive, values available starting from 1st value
● Request reference mirrored:
The values correspond to the values from the request.
● Format:
06 hex → Parameter values are in the unsigned16 format.
● Number of values:
08 hex → 8 parameter values are available.
● 1st value ... 8th value:
In the fault buffer of drive 2, a fault is only entered in the 1st value.

Example 2: Writing parameters (multi-parameter request)
Preconditions
● The PROFIdrive controller has been commissioned and is fully operational.
● PROFIdrive communication between the controller and the device is operational.
● The controller can read and write data sets in conformance with PROFINET/PROFIBUS.
● Special requirements for this example:
Control mode: Vector control (with extended setpoint channel)
Task description
Jog 1 and 2 are to be set up for drive 2 (also drive object number 2) via the input terminals of
the Control Unit. A parameter request is to be used to write the corresponding parameters as
follows:
•
BI: p1055 = r0722.4
Jog bit
0
•
BI: p1056 = r0722.5
Jog bit
1
•
p1058 = 300 rpm
Jog 1 speed setpoint
•
p1059 = 600 rpm
Jog 2 speed setpoint
The request is to be handled using a request and response data block.
