Corrected from:
- i700 servo inverter V01.05.06.9665
Response of the new version:
When using the operating modes without position control (csv, cst, vl), the current following error (0x60F4) is now permanently set to zero.
In this way, an unintentional response of the following error monitoring is no longer possible if the monitoring has accidentally been set too active in the controller.
At the same time, the status bits in the CiA401 status word for "FollowingError" and "TargetReached" are no longer updated; they remain permanently set to 0.
What happens?
The current following error (0x60F4) generated by the i700 can rise to implausibly high values.
As a result, the following error monitoring may respond unexpectedly.
When does the problem occur?
The problem occurs with the operating modes without position control (csv, cst, vl), in particular with V/f characteristic control without feedback system.
The parameter 0x60F4 is contained in the PDO mapping (Lenze setting) and therefore cyclically transferred to the controller.
The following error monitoring may respond unexpectedly (if it is accidentally activated for an operating mode without position control).
Which products are affected?
- i700 servo inverter ≤ V01.04.00.9125
Short-term measures/recommendations:
None.
Evaluation:
In the application program of the controller, the current following error is usually only a display value without further effects on the application.
Only the following error monitoring responds to the current following error, if it is activated. An activation of the following error monitoring is, however, only useful, if a feedback system is available and the following error can actually be compensated via the position controller.
