6SE7087-2JD60 Siemens AG
10-12 Operating Instructions SIMOVERT MASTERDRIVES
Bit 6: Message "Power-on inhibit" (H)
POWER-ON INHIBIT (008) status
♦ The power supply, open-loop and closed-loop control are
operational.
♦ If an external power supply and a main contactor (option)/bypass
contactor are available, it is possible to bring the DC link voltage in
this drive converter status into a no-voltage condition!
♦ The message is available as long as an OFF2 command is present
via control word bit 1 or an OFF3 command is available via control
word bit 2 after the setpoint has been ramped-down, or an ON
command is available via control word bit 0 (edge evaluation).
Bit 7: Message, "Alarm" (H)
Alarm (Axxx)
♦ An alarm has been issued.
♦ The signal is present until the cause has been resolved.
Bit 8: Message "Setpoint-actual value deviation" (L)
Alarm, "Setpoint-actual value deviation" (A034)
♦ The frequency actual value deviates from the frequency setpoint
(reference value, by a value which exceeds P794 (setpoint-actual
value deviation, frequency), for a time which is longer than P792
(setpoint-actual value deviation time).
♦ The bit is again set as H signal, if the deviation is less than
parameter value P792.
Bit 9: Message "PZD control requested" (H)
Still present.
Bit 10: Message, "Comparison frequency reached" (H)
The parameterized comparison frequency has been reached.
♦ The absolute frequency actual value is greater than or equal to the
parameterized comparison frequency (P796).
♦ The bit is again set to L signal, as soon as the absolute value of the
comparison frequency (P796), minus the parameterized comparison
frequency hysteresis (P797 as %, referred to the comparison
frequency (P796)) is fallen below.
