F07806 Drive: Regenerative power limit exceeded (F3E)
Reaction: OFF2 (IASC/DCBRAKE)
Acknowledge: IMMEDIATELY
Cause: For blocksize power units, types PM250 and PM260, the regenerative rated power r0206[2] was exceeded for more
than 10 s.
See also: r0206 (Rated power unit power), p1531 (Power limit regenerative)
Remedy: - increase the down ramp.
- reduce the driving load.
- use a power unit with a higher regenerative feedback capability.
- for vector control, the regenerative power limit in p1531 can be reduced so that the fault is no longer triggered.
F07810 Drive: Power unit EEPROM without rated data
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: No rated data are stored in the power unit EEPROM.
See also: p0205 (Power unit application), r0206 (Rated power unit power), r0207 (Rated power unit current), r0208
(Rated power unit line supply voltage), r0209 (Power unit, maximum current)
Remedy: Replace the power unit or inform Siemens Customer Service.
