• Set-up the value in % of the rated torque.
• The right figure shows an example that the
maximum torque is limited to 150% of the rated
torque.
• This parameter limits the maximum torque in both
CW and CCW directions.
< N o t e s >
• Pr5E "Torque limit set-up" disables set-up in excess of the values set up for the system
parameter "Max. torque set-up".
• The system parameters are fault parameters that cannot be changed with PANATERM
or on the operation panel.
You can add a quasi S-shaped acceleration/deceleration to the
0 ~
velocity command, so that smooth operation can be obtained in
500
such a case as a large impact shock will be given at starting or
[ 0 ]
stopping with a linear acceleration/deceleration.

• You can limit the max. motor torque with this parameter.

• In normal specifications, the amplifier can produce 300 % of the rated torque
500
for a short duration(peak-torque). Use this limiting function when 300%
[300]
torque may cause the trouble to the machine.
