Description:
This actuation of these parameters occurs as presented in the Figure 12.13 on page 12-24 next.
The passage through the avoided speed range (2 x P0306) takes place by means of the acceleration/deceleration
ramps.
The function does not operate properly if two bands of "Skip Speed" overlap.
NOTE!
T
he speed references that do not pass through the speed ramp, as JOG+, JOG-, P0231, P0236, P0241 or
P0246 = 1, are not considered
.

12.10 SEARCH OF ZERO OF THE ENCODER
The zero search function attempts to synchronize the minimum counting or the maximum counting visualized in
the parameter P0039. Accountant of the Pulses of Encoder, with the pulse of zero of the encoder.
The function is activated by setting P0191 = 1. It will just be executed once, when happening the first zero
pulse after the activation of the function.
Among the actions accomplished are: the parameter P0039 is reduced to zero (or fitting with the value of 4 x P0405),
and the parameter P0192 starts to indicate P0192 = Completed.

Description:
On the inverter initialization, the parameter P0191 starts on zero. By setting to one, it activates the operation of the
zero search function, while the parameter P0192 stays on zero (Inactive).
