the position of the machine at any time. However, the data may be lost when power to the ELC
is turned off. Therefore, the machine should execute a zero point return at power up.

M1346, refer to the ABSR (API 155) instruction.
9. Zero return output addresses in the two ELC models
Model ELC-PH ELC-PV
Zero return output Y10, Y11 Y0, Y2, Y4, Y6
Program Example:
When M10=ON, pulses at a frequency of 20KHz in an ELC-PH controller are sent out Y10 to make
the motor execute a zero point return. When it reaches the near point signal (DOG), X10=ON and it
will change to creep speed. At this time, pulses will be sent out Y10 at a frequency of 1KHz. The
pulse output will not stop until X10=OFF.

The Timing Chart of the reset signal
1. Timing chart of the reset signal output for ELC-PV series. (ELC-PH series does not support
this function.)
a) When the reset signal flag M1346 = On, after zero return is completed, the ELC can send
the reset signal to the servo drive for approximately 20ms. After 20ms, the reset signal will
return to Off again.
b) Output addresses for reset signals of ELC-PV series:
CH0 (Y0, Y1) reset output device (Y10)
CH1 (Y2, Y3) reset output device (Y11)
CH2 (Y4, Y5) reset output device (Y12)
CH3 (Y6, Y7) reset output device (Y13)
