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. Y002 (pulse output destination) cannot be specified when the 14-point or 24-point type FX
connected.
*3. Devices related to Y003 (pulse output destination) are only valid if two FX
connected to the FX
Caution:
• When using the transistor outputs of the main unit, set the pulse frequency for the zero return speed to less than
100 kHz.
If a pulse higher than 100 kHz is output from a transistor output of the main unit to perform an operation, PLC failure
may occur.
• Set the zero return speed so that the set value of the zero return speed is less than the maximum frequency value
of the servo amplifier (driver unit).
