As shown in the figure below, when the value of the speed feedback goes under the ZSPD
output range (0x2404), the ZSPD (0 speed) signal is displayed. If the value goes over the
TGON output range (0x2405), the TGON (motor revolution) signal is displayed.

And when the difference between the command and the speed feedback, that is, the speed
error is within the INSPD output range (0x2406), the INSPD(speed match) signal is
displayed.
