The programs shown in this chapter use 1 axis for Y000 (pulse output destination device). If other pulse
output destination devices are used, modify corresponding device numbers shown in the table below when
referencing the description.

To use the "forward rotation pulse train" signal and "reverse rotation pulse train" signal of a FX
2HSY-ADP, change the name of this signal to "forward rotation pulse train" signal when reading the
description.
To use the "forward rotation pulse train" signal and "reverse rotation pulse train" signal of a FX
2HSY-ADP, change the name of this signal to "reverse rotation pulse train" signal when reading the
description.
If an FX PLC below Ver.2.20 is used, exchange the direction signal output number with the CLEAR
3UC
signal output number.
If the absolute position detection system is used, and if the DSZR instruction and ZRN instruction are
not used for the first zero return, this signal is not needed. To use the absolute position detection
system, refer to the following chapter and manual.
To use the ZRN instruction for zero return, assign the input number of the near-point signal (DOG) to
the zero-phase signal. This is needed since the ZRN instruction will not use the zero-phase signal.
