Setup
Unit
range
10 to 100 0.1V/ You can set the relation between the voltage applied to the torque
<30> 100% command input (SPR/TRQR : CN X5, Pin-14 or CCWTL/TRQR : CN X5,
Pin-16) and the motor output torque.
• Unit of the setup value is [0.1V/100%]
and set up input voltage necessary to
produce the rated torque.
• Default setup of 30 represents
3V/100%.
0 to 1 – You can reverse the polarity of the torque command input (SPR/TRQR :
<0> CN X5, Pin-14 or CCWTL/TRQR : CN X5, Pin-16)
Setup value
<0>
1
0 to 500 % You can limit the max torque for both CCW and CW direction with Pr5E.
Pr03 setup and Pr5F are ignored.
<500>
*2
This torque limit function limits the max. motor torque with the
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.
• Setup value is to be given in
% against the rated torque.
• Right fig. shows example of
150% setup with Pr03=1.
• Pr5E limits the max. torque for
both CCW and CW directions.
<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
value varies depending on the combination of the motor and the driver.
For details, refer to P.57, "Setup of Torque Limit " of Preparation.
