Series: G115D
Drive: Maximum DC bus voltage controller active
converter
Meaning: The DC bus voltage controller has been activated because the upper activation threshold (r1242, r1282) was exceeded. The ramp-down time is automatically increased to keep the DC bus voltage (r0070) within the permissible limits. A control deviation exists between the speed setting and the actual speed. Therefore, when the DC bus voltage controller is deactivated, the ramp-function generator output is set to the speed setpoint. See also: r0056 (Closed-loop control status word), p1240 (Vdc controller configuration (vector control)), p1280 (Vdc control or Vdc monitoring configuration (V/f)).

Drive: Maximum DC bus voltage controller active
converter
Meaning: The DC bus voltage controller has been activated because the upper activation threshold (r1242, r1282) was exceeded. The ramp-down time is automatically increased to keep the DC bus voltage (r0070) within the permitted limits. A control deviation exists between the speed setting and the actual speed. Therefore, when the DC bus voltage controller is disabled, the ramp-function generator output is set to the speed list value.

Drive: Maximum DC bus voltage controller active
converter
Meaning: The DC bus voltage controller was activated because the upper activation threshold (r1242, r1282) was exceeded. The ramp-down time is increased automatically to keep the DC bus voltage (r0070) within the permissible limits. A control deviation exists between the speed reference and the actual speed. Therefore, when the DC bus voltage controller is disabled, the ramp-function generator output is set to the speed list value.

Drive: Maximum DC bus voltage controller active
converter
Meaning: The DC bus voltage controller was activated because the upper activation threshold (r1242, r1282) was exceeded. The ramp-down time is automatically increased to keep the DC bus voltage (r0070) within the permissible limits. A control deviation exists between the speed setpoint and the actual speed. Therefore, when the DC bus voltage controller is disabled, the ramp-function generator output is set to the actual speed. Once the condition has persisted beyond the standstill detection waiting time p1227, the converter automatically enters pulse inhibit (OFF2).
