Parameters for Torque Control
PrNo.
Parameter Range
Function
description
You can invert the polarity of the torque command input signal
(TRQR: CN I/F Pin 14) when Pr02 = 5.
When the driver has been configured for torque control, the torque
command signal input uses CN I/F Pin 16.
・ You can limit the max. motor torque with this parameter.
・ In normal specifications, the driver can produce 300 % of the
rated torque for a short duration(peak-torque). Use this limiting
function when 300% torque may cause the trouble to the
machine.

set-up
・ The unit of the set-up is [0.1V/100%]. Enter the
required voltage for producing the rated torque.
・ The default value of 30 corresponds to 3V/100%.

・ Set-up the value in % against 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.

<Notes>
You can't set-up a greater value with this parameter than default value (300%), which is
defined by the system parameter (Max. torque output).
