Pulse In-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
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).
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.
