Bit 23: Reserve
Bit 24: Enable-droop command (H "Droop enable")
HIGH signal
♦
This command enables the droop function if P290 = 0 has been
assigned, parameter P246 is <> 0 and the inverter pulses of the
converter have been enabled.
The speed-controller output negatively linked back to the speed
setpoint can be set via parameters P245 (droop) and P246 (droop
gain).
Refer to function diagram "Speed controller" 360
Bit 25: Controller enable command (H "controller enable")
HIGH signal and the drive converter inverter pulses are enabled.
♦
The output of the speed controller is enabled when P290 = 0
(current control).
Refer to function diagram 360
Bit 26: Command, external fault 2 (L "External fault 2")
LOW signal; it is only activated from the READY (011) condition
onwards and after an additional time delay of 200 ms.
♦
FAULT (007) and fault message (F036).
The inverter pulses are inhibited, the main contactor, if available, is
opened.
Bit 27: Slave/master drive command (H "Slave drive")/(L "Master drive")
HIGH signal, P290 = 0 and enabling of the inverter pulses of the
converter.
♦
Slave drive: The closed-loop control acts as closed-loop torque
control (M closed-loop control).
LOW signal, P290 = 0 and enabling of the inverter pulses of the
converter.
♦
Master drive: The closed-loop control function acts as a closed-loop
speed control function (n-control).
