S200: Motor Current Control Specifications

NOTE: Unless otherwise specified, the specifications are worse-case limits and apply over the specified operating ambient temperature and over the specified operating line voltage.

Parameter
Rating
Motor Phase Current Waveform
(In Sine or six-step mode output torque = Motor KT* Drive IFB)
 Pure sinusoidal or 6-step, depending on feedback device.
Motor Shaft Torque
(Ignoring motor magnetic saturation)
  
   Peak (hot motor winding)
   Multiply KT * 1.06 for cold motor    winding (AKM or PMA motors).
 KT (N-m/ARMS) * Drive Ipeak (ARMS)
   Instantaneous
 KT (N-m/ARMS) * IFB (ARMS)
