Setting of Zero Return Speed (DSZR/ZRN Instruction)

Use the related device or the operand of the instruction to set the zero return speed.
The zero return speed setting range is shown in the following table.
Be sure to set the zero return speed so that the relation with the other speeds can be "bias speed ≤ zero
return speed ≤ maximum speed". If the set value of the zero return speed is more than the maximum speed
value, operation will be performed at the maximum speed.

*2. Devices related to Y003 (pulse output destination) are valid only if two FX
connected to the FX
Caution:
• When using the transistor output of main unit, set the pulse frequency for zero return speed less than 100,000 Hz.
If the transistor output (Y000, Y001, Y002) of the main unit uses a pulse frequency of more than 100,000 Hz to
perform operation, the PLC may be damaged.
• Set the zero return speed so that the set value of the zero return speed can be less than the maximum frequency
value of the servo amplifier (driver unit).
