SIMOVERT MASTERDRIVES
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
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
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.
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).
