Other parameters in the Motor Control category that work together with syncadv:

fmax

Maximum motor frequency. RPM = fmax × 60 / polepairs.

boost

dig

Voltage at 0 RPM — controls starting torque. Higher = stronger launch.

fweak

Field weakening start frequency. Above this, motor enters constant-power region.

numimp

ppr

Speed sensor pulses per revolution.

polepairs

Motor pole pairs. CRITICAL — set this correctly for your motor.

fslipmax

Maximum slip frequency (induction motors). Sets full-throttle torque.

snsm

enum

Motor temperature sensor type. Must match your motor's actual sensor.

fslipmin

Minimum slip frequency (induction motors). Sets creep torque.

encmode

enum

Encoder/position sensor type. This is your motor's 'eyes' — it tells the inverter where the rotor is.

dirchrpm

rpm

RPM below which direction change is allowed.
