PulseIn-position range
You can set up the timing to feed out the positioning complete signal
(COIN : CN X5, Pin-27). 
The positioning complete signal (COIN) will be fed out when the deviation
counter pulse counts fall within ± (the setup value), after the position
command entry is completed.
The setup unit should be the encoder pulse counts at the position control
and the external scale pulse counts at the full-closed control.
• Basic unit of deviation pulse is encoder "resolution", and varies per
the encoder as below.
(1) 17-bit encoder : 2
17
= 131072
(2) 2500P/r encoder : 4 X 2500 = 10000
<Cautions>
1. If you set up too small value
to SV.Pr60, the time until the
COIN signal is fed might
become longer, or cause
chattering at output.
2. The setup of "Positioning
complete range" does not
give any effect to the final
positioning accuracy.

1st torque limit 
2nd torque limit
You can set up the limit value of the motor output torque (SV.Pr5E : 1st
torque, SV.Pr5F : 2nd torque). For the torque limit selection, refer to
SV.Pr03 (Torque limit selection).
<Caution>
You cannot set up a larger value to this parameter than the default setup
value of "Max. output torque setup" of System parameter (which you
cannot change through operation with PANATERM
®
or panel). Default
value varies depending on the combination of the motor and the driver.
For details, refer to P.78, "Setup of Torque Limit " of Preparation.
• Setup value is to be given in
% against the rated torque.
• Right fig. shows example of
150% setup with SV.Pr03=1.
• SV.Pr5E limits the max.
torque for both CCW and CW
directions.
This torque limit function limits the max. motor torque inside of the
driver with parameter setup.
In normal operation, this driver permits approx. 3 times larger torque
than the rated torque instantaneously. If this 3 times bigger torque
causes any trouble to the load (machine) strength, you can use this
function to limit the max. torque.
