E XPLANATION
This example shifts the home position (zero position)
from the C pulse location to a different location. After
searching the C pulse with the HOME_C command the
motor moves to position 7800 UU. When the motor is
theoretically on position 7800 UU the scale is changed
and Position_Demand_Value is set to zero.
Position_Actual_Value is Position_Demand_Value plus
Following_Error_actual_Value.
N OTES If error 9 (“Wrong motion mode for
SET_ZERO_POSITION command. Set STOP_EX
command before”) occurs, insert a STOP_EX command
before the SET_ZERO_POSITION command.
