P14 Orientation
completion
scope

Set orientation completion pulse range under the mode
of position control;

This parameter provides the basis whether the
orientation is completed determined by drive under the
position control mode; when the remaining pulse in the
position deviation counter is less or same as its set value,
the drive will determine the orientation is completed, with
signal COIN ON; otherwise, will be COIN OFF.

P15 Position
deviation
alarm
range

When it is set as 0, disable position alarm detection is
invalid;

Disable position alarm detection is valid when it is not
0, and this parameter provides the basis whether
deviation is too large determined by drive under the
mode of position control; When the remaining pulse in
the deviation counter is less or same as its set value, the
drive will determine the position to not disable without
alarm display; otherwise, alarm ER0-04 will occur.

P16 Position
gain

Set the proportional gain for position loop regulator;

Bigger in set value, higher in gain and rigidity. Under
the condition of identical frequency command pulse,
position lag will be smaller; however, too big value will
lead vibration and over-regulation of system;

The principle of debugging is to possibly adjust this
parameter to be bigger, under the situation of
guaranteeing the system to operate without vibration
and jitter.

feed-
forward

Set position loop feed-forward coefficient ;

When it is set as 0, no feed-forward coefficient is added;
Bigger in set value, bigger in feed-forward;
When position loop fee-forward is bigger, the high-speed
response property of control system is better.

smoothing
constant

Smoothing filter is conducted for command pulse;
acceleration and deceleration values with exponential
form indicate the acceleration and deceleration.

Filter will not lose pulse; command delay will exist yet;

Main applications:
Host computer controller has no acceleration and
deceleration functions;
