Bit 10: Message "Comparison value reached" (H)
The parameterized comparison value has been reached.
♦ The actual value is greater or equal to the parameterized
comparison value (P796).
♦ The bit is re-set to the L signal as soon as the actual value falls
below the comparison value (P796) minus the parameterized
comparison-value hysteresis (P797 in % in relation to the
comparison value (P796)).
(See also function diagram 480).
Bit 11: Message "Fault, undervoltage" (H)
"Undervoltage in the DC link"
♦ The DC link voltage has fallen below the permissible limit value.
From drive state (°011) there is an additional fault message (F008)
"DC link undervoltage".
Refer to the Section "Fault- and alarm messages"
Output at the terminal strip with L signal.
Bit 12: Message "Main contactor energized" (H)
The main contactor/bypass contactor (option) is energized.
♦ The main contactor/bypass contactor (option) can be driven with the
appropriate wiring and parameterization.
Bit 13: Message "RFG active" (H)
Ramp-function generator active
♦ The ramp-function generator output (KK0073) is not equal to the
ramp-function generator input (KK0072).
Bit 14: Message, "Clockwise rotating field" (H)/"Counter-clockwise rotating field" (L)
Clockwise rotating field
♦ The speed setpoint for closed-loop control (speed setpoint r472 /
KK0075) is greater or equal to 0.
Counter-clockwise rotating field
♦ The speed setpoint for closed-loop control (speed setpoint, r472 /
KK0075) is smaller than 0.
