inhibit way
When the machine touches the mechanical limit
switch and strike CW/CCW limit , you can
choose the following methods to prohibit with
this parameters.
0: To limit the torque in this direction to be 0.
1: To prohibit the input pulse in this direction.

PA-84
Hysteresis for
positioning
completion
1.Set pulse completion range in position control
mode.
2. When the number of remaining pulses in the
position deviation counter is less than or equal to
the setting value of this parameter, the digital
output of COIN( position completion) is ON,
otherwise OFF.
3.Comparator has the function of hysteresis,
which is set by PA85.

PA-85
The range of
near position
1. To set the pulse range of near position under
the position control mode.
2. When the pulse number in position deviation
counter is smaller than or equal to the setting
value of this parameter, the digital output (DO)
NEAR(approach position) is ON, otherwise is OFF.
3. The comparator has hysteresis function set by
PA86.
4. Use this function in case that in near
positioning, the host controller is accepting the
NEAR signal to carry on the preparation to the
next step. In general, this parameter value should
be bigger than PA-16.

Hysteresis of
arrival speed
1.
When the motor speed exceeds this parameter,
the digital output ASP ( speed arrival) is ON,
otherwise OFF.
2.
The comparator has hysteresis function.
3.
It has polarity setting function:
