Information about the parameter response:

●Request reference mirrored:

This response belongs to the request with request reference 25.

●Response ID:

01hex ––> Read request positive, values stored as of 1st value

●Axis mirrored, no. of parameters:

The values correspond to the values from the request.

●Format:

06hex ––> Parameter values are in Unsigned16 format.

●No. of values:

08hex ––> 8 parameter values are available.

●1. value ... 8th value

A fault is only entered in value 1 of the fault buffer for drive 2.

10.1.4.5Example 2: write parameters (multi-parameter request)

Prerequisites

1.The PROFIdrive controller has been commissioned and is fully operational.

2.PROFIdrive communication between the controller and the device is operational.

3.The controller can read and write data sets in conformance with PROFIdrive DPV1. Special requirements for this example:

4.Control type: Vector, servo with activated "Extended setpoint channel" Function Module

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 1/min	Jog 1 speed setpoint
•	p1059 = 600 1/min	Jog 2 speed setpoint
