The actual setpoint value will be calculated from the differential of positive and negative inputs. This eliminates error from ground currents and also reduces sensitivity to EMI noise. | The actual setpoint value will be calculated from the differential of positive and negative inputs.

Peak torque can be configured to drive with [[GDtool]] as peak current limit. Torque and current are directly proportional, so torque setpoint is also a current setpoint. | Peak torque can be configured to drive with [[GDtool]] as peak current limit.
