SBus: Up to 64 nodes, cable length varies with baud rate (320m at 125kbaud)

RS-485: Up to 32 units, cable length ≤ 200m

EMC protection: Standard input filter (Class A) for size 1/2, optional for size 3-5; Shielded cable and output reactor (HD series) are required on the motor side

Start the process

Starting premise

Complete installation inspection to prevent accidental motor start-up (such as disconnecting X13 terminal block)

Preset parameters: Restore factory settings or configure parameters according to application settings

Startup method

Key points for operating the applicable mode of startup mode

DBG11A keyboard VFC mode requires input of motor model, rated voltage/frequency, encoder type and other data, supporting speed controller startup

MOVITOOLS software VFC/CFC/SERVO mode connection USS21A option (RS-232/RS-485), supports asynchronous/synchronous motor settings, and can batch copy parameters

Motor starting method

Analog quantity given: Input 0-10V or 4-20mA signal through AI1 terminal

Fixed setting value: Select preset speed (n11/n12/n13) through DI terminal combination

Manual operation: DBG11A keyboard control, 7-segment code displays “H”, speed adjustment speed is 150rpm/s

Operation and maintenance

Operation display

7-segment code display: There are a total of 16 states (such as “0”=not ready, “F”=fault flashing, “H”=manual mode)

DBG11A keyboard: supports parameter copying, language switching (German/English/French), and quick menu operations

Fault handling

Fault storage: Record the last 5 faults (including status, current, temperature, and other information)
