Hi,

The gate signal of the high side FET does not become HI continuously for 2 steps.

It occurs at a speed between 12000PPS and 18000PPS.  It does not occur until the speed of 11000PPS and at the speed of 20000PPS.

It does not occur except for Auto Mixed Decay.

What is the cause?

MODE: 1/4 step
Motor Current: 4.2A
ISGAIN: Gain of 10
TORQUE: 129
DECAY: Auto Mixed Decay
TBLANK: 1us
Toff: 8.5us
Speed: 12000PPS to 18000PPS

Regards,

HM
