Current Selection: Peak current Ip(A) ≥ 2 × rated motor current Ir(A), or Ip(A) ≥ 4 × rated motor power Pr(W) ÷ rated voltage Vr(V)
Driving Quadrant: Designed for I & III quadrant operation only
Brake Operation: Motor stops quickly via winding shorting through bottom MOSFETs when BK port is low level
Cable Management: Hall signals may be disturbed by switched current in winding leads exceeding 500mm. Use shielded leads and avoid intertwining.
Motor Insulation: Hall sensors to windings, Hall sensors to motor case, and windings to motor case must have insulation resistance > 500MΩ @ 500VDC and dielectric strength
