(oversimplified chart, but has major concepts)
As the rpm approaches zero, power approaches zero. Spin the motor faster. When you’re holding it, it’s near or at zero speed.
Set motor current (phase amps in the chart above) higher than battery current. That particular motor is rated for 50A so I would enter 50A and -50A in the top boxes. Setting the battery/power_supply current at 10A or 20A is fine. You won’t have low speed torque if you put low numbers in the top box.
The bottom panel controls erpm and you’re measuring rpm probably. They will be directly proportional by the number of magnetic pole pairs. A 14 pole motor has 7 pole pairs. So in theory erpm = 7 · rpm
