p0972 Drive unit reset / Drv_unit reset
Access level: 3
Can be changed: U, T
Units group: -

Description: Sets the required procedure to execute a hardware reset for the drive unit.
Value: 0:
1:
2:
3:
Danger: It must be absolutely ensured that the system is in a safe condition.
The memory card/device memory of the Control Unit must not be accessed.
Note: If value = 1:
Reset is immediately executed and communications interrupted.
After communications have been established, check the reset operation (refer below).
If value = 2:
Help to check the reset operation.
Firstly, set p0972 = 2 and then read back. Secondly, set p0972 = 1 (it is possible that this request is possibly no lon-
ger acknowledged). The communication is then interrupted.
After communications have been established, check the reset operation (refer below).
If value = 3:
The reset is executed after interrupting cyclic communication. This setting is used to implement a synchronized
reset by a control for several drive units.
If the cyclic communication is active for both PROFIdrive interfaces, then the reset is executed after completing
both cycle communications.
After communications have been established, check the reset operation (refer below).
To check the reset operation:
After the drive unit has been restarted and communications have been established, read p0972 and check the fol-
lowing:
p0972 = 0? --> The reset was successfully executed.
p0972 > 0? --> The reset was not executed.

Description: Displays the parameters that exist for this drive.
Dependency: Refer to: r0981, r0989
Note: The existing parameters are displayed in indices 0 to 298. If an index contains the value 0, then the list ends here.
In a long list, index 299 contains the parameter number at which position the list continues.
This list consists solely of the following parameters:
r0980[0...299], r0981[0...299] ... r0989[0...299]
The parameters in this list are not displayed in the expert list of the commissioning software. However, they can be
read from a higher-level control system (e.g. PROFIBUS master).
