4. Select one of the following methods for the initial reading of present absolute position.
a) Complete zero point return by using reset signal function to execute API 156 ZRN instruction.
b) After using JOG or manual operation to adjust the zero point position, input a reset signal in SERVO AMP.
See the figure of external switch below for whether to use DVP-PLC for output. For the wiring of DVP-PLC
and Mitsubishi MR-H2-□A, see remarks of API 159 DRVA instruction.

5. Flags explanation:
M1010： (For EH/EH2/SV series MPU) When M1010 is On, CH0 (Y0, Y1) and CH1 (Y2, Y3) will output pulses
while END instruction is being executed. When the output starts, M1010 will automatically turn Off.
M1029： (For EH/EH2/SV series MPU) When the first group CH0 (Y0, Y1) pulse output or the execution of
other relevant instructions are completed, M1029 will turn On.
M1030： (For EH/EH2/SV series MPU) When the second group CH1 (Y2, Y3) pulse output is completed,
M1030 will turn on.
M1102： (For SC series MPU) When the first group CH0 (Y10) pulse output is completed, M1102 will turn On.
M1103： (For SC series MPU) When the second group CH1 (Y11) pulse output is completed, M1103 will turn
On.
M1258： (For EH/EH2/SV series MPU) When M1258 is On, CH0 (Y0, Y1) will output reverse pulses.
M1259： (For EH/EH2/SV series MPU) When M1259 is On, CH1 (Y2, Y3) will output reverse pulses.
M1305： (For EH/EH2/SV series MPU) PLSV, DPLSV, DRVI, DDRVI, DRVA, DDRVA instructions for CH0
