Which products are affected?
9300EP position controller V7.0
9300ES servo controller V7.0
Eliminated function restriction
In case of the 9321 to 9324 devices code C0022 can be used to choose between IMAX ≤ 1.5 • Irated (standard variant) and IMAX ≤ 2.0 • Irated (acceleration variant). The torque deviations occurring immediately after the changeover are much more intensive in case of the acceleration variant compared to the standard variant used before. The situation cannot be improved by another current transformer offset adjustment produced by mains connection.
Now, the offset values determined during the offset adjustment are automatically adjusted to the changed scaling in case of the acceleration mode. As a result, the drive performance is improved.
Which products are affected?
9300EP position controller <= V6.2
9300ES servo controller <= V6.2
What happens?
In case of the 9321 to 9324 devices code C0022 can be used to choose between IMAX ≤ 1.5 • Irated (standard variant) and IMAX ≤ 2.0 • Irated (acceleration variant). The torque deviations occurring immediately after the changeover are much more intensive in case of the acceleration variant compared to the standard variant used before. The situation cannot be improved by another current transformer offset adjustment produced by mains connection.
When does the problem occur?
The problem occurs if the acceleration mode has been selected (C0022 > 1.5 x Irated).
Possible diagnostics?
Look at the drive performance.
Short-term measures/recommendations?
None.
Evaluation:
The influence of the concentricity properties depend on the application.
