Example: P2-66 can be used to determine the value of P1-46 as the
number of single-phase pulse output or the number of pulses
after 4 times. For detailed settings, please refer to P2-66.
The pulse number setting of P1-46 and the current motor rotation
speed will determine the output width of Z pulse. When the speed
is faster, the pulse width is relatively smaller. In order to avoid the
width being too small, when the host controller cannot receive the
pulse, the servo drive has a minimum output pulse width of 250
μ
s. When the width is smaller than this value, 250
μ
s will still be
output.
In the following example, the speed is 3000 r/min and the pulse
number setting of P1-46 is 2500 pulse.

This value is less than
250
μ
s, so the bandwidth of the servo drive OCZ signal will be
latched at 250
μ
s. If this value is higher than 250
μ
s, the higher
value will precede.
NOTE
The following circumstances might exceed the max. allowable
input pulse frequency and occurs AL018:
1. Encoder error
2.
Motor speed is above the value set by parameter P1-76
