Setting of Creep Speed (DSZR/ZRN Instruction)

Use the related device or the operand of the instruction to set the creep speed.
The creep speed setting range is shown in the following table.
Be sure to set the creep speed so that the relation with the other speeds is "bias speed  creep speed 
32767 Hz

Setting of Maximum Speed

Set the maximum speed to determine the upper limit value for the output pulse frequency and the zero return
speed.
Use the devices shown in the following table to determine the maximum speed for each pulse output
destination device.

Caution:
• To use the main unit (transistor output), set the output pulse frequency (absolute value) to 100,000 Hz or less.
If more than 100,000 Hz is output from the transistor output of the main unit to perform operation, it may cause PLC
failure.
• Set the output pulse frequency so that the output pulse frequency value is less than the maximum frequency value
of the servo amplifier (driver unit).

If the maximum speed is set to less than 32767 Hz, note that this value (32767 Hz) will automatically
be changed to the maximum speed.
