Getting the Drive Ready
The ready state indicates that the Drive is ready to run. Until the Drive is ready, all run commands are ignored.
Apply control power to the drive. Control power provides power to run the Drive inverter and the HMI. The HMI
will turn on, and the fans on the inverter cabinet will start.
CAUTION : The drive is not equipped with a power switch of any type. Control and Main power
must be supplied separately by means of appropriate line application equipment or switchgear.
Contact Benshaw for assistance in the selection of applicable devices.
NOTE : If main power (e.g. 4160V nominal) is not applied, a “No DC Bus Fault” will occur. After
main power is applied, press the Reset button next to the fault name on the HMI
NOTE : If a series of question marks are displayed on the HMI over each display field, there is a
failure in connectivity between the Drive inverter and the HMI. Check to ensure proper seating
of the interconnection cables.
The automatic pre-charge sequence of the cell capacitors will initiate on start-up. When the pre-charge is
complete, and any fault or lockout conditions are cleared, the Main view will indicate a ready state.
