Q How to activate an output/relay in case of a warning?
A Set Pr03-00/03-01=20.
Q Why does Pr07-01 display the wrong value?
A This is a bug in firmware 1.23/2.23.
After setting Pr07-01, it shows the wrong value after power off/on. The internal value
of Pr07-01 is still correct, only the display value is wrong. It will be corrected in the
next firmware.
Q How does OPL work and which parameters to set?
A See user manual (Sensorless Vecotr Control Compact Drive VFD-E Series user
manual) but some parameter descriptions and explanations are not correct.
Ramping will be done by DC-braking.
Same as Pr06-46 in C20000/MS300. It should be Detection Time of Output Phase
