Mode 21

Circumstance 1: MC_Home instruction is executed and the axis moves in the negative direction at the

first-phase speed while the home switch is OFF. The motion direction changes and the axis

moves at the second-phase speed once the home switch becomes ON. And where the axis

stands is the home position at the moment the home switch becomes OFF.

Circumstance 2: MC_Home instruction is executed and the axis moves in the positive direction at the

second-phase speed while the home switch is ON. And where the axis stands is the home

position at the moment the home switch becomes OFF.

 Mode 31 and mode 32 Reserved for future development.

 Mode 33 ~ mode 34 Homing which depends on Z pulse

In mode 33, MC_Home instruction is executed and the axis moves at the second-phase speed in the negative

direction. And the place where the axis stands is the home position once the first Z pulse is met.

In mode 34, MC_Home instruction is executed and the axis moves at the second-phase speed in the positive

direction. And the place where the axis stands is the home position once the first Z pulse is met.
