Current Selection: Driver peak current should be at least 2x motor rated current or calculated as 4x motor rated power divided by rated voltage.
Operating Quadrant: Designed for operation in I & III quadrants only.
Frequency Control: Optional F-V transfer module enables 0-3kHz frequency control at SV port.
Brake Operation: BK port low level triggers quick motor stop via winding shorting through bottom MOSFETs.
Cable Management: Keep Hall signal leads separate from winding cables (max 500mm length) to prevent interference.
Insulation Requirements: Hall sensors to windings, Hall sensors to motor case, and windings to motor case must maintain >500MΩ insulation resistance at 500VDC.
