Set up the Z phase regenerative width of external scale in unit of time. Even if the width of
Z phase signal cannot be detected because the width equivalent of the travel distance from
the external scale is too short, the Z phase signal will be output for at least the period set to
this parameter.

Full-closed control using serial absolute external scale. When outputting pulses by using the
external scale as the source of the output, set the Z phase output interval in units of A phase
output pulses of the external scale (before multiplied by 4).

After the power is fed to the driver, the Z phase, as it crosses the zero at
the absolute position of external scale, is output in synchronous with the
A phase. Subsequently, the Z phase is output at the A phase output pulse
intervals set to this parameter.
When Pr6.58 ≠ 0, The absolute position output of the external scale is identical to the Z
phase of the Pr6.58 setting value.

Serial absolute external scale
• After the driver control power supply is turned on, the Z-phase is output for the first time
only when the external scale absolute position zero is traversed, and, using this position as a
datum, the Z-phase is output with the A-phase pulse interval that is set by Pr6.21. However,
when Pr6.21 = 0 is true, the Z-phase is output only at the absolute zero position.
• The first Z-phase output after switching on the driver control power supply can be set to any
external scale absolute position by the setting of Pr6.58. This function assumes use in case
absolute zero position of external scale does not exist within the movable range of the machine.
