• The unit of the set-up is [0.1V/100%]. Enter the required volt-
(continued)
age for producing the rated torque.
• The default value of 30 corresponds to 3V/100%.

Torque limit

• Set-up the value in % against the rated torque.
• The right figure shows an example that the maxi-
mum 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 >
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).
0 ~ 1
You can invert the polarity of the torque command input signal
[0]
(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.

Å E You can limit the max. motor torque with this parameter.
0 ~
Å E In normal specifications, the driver can produce 300 % of the
500
Å@ rated torque for a short duration(peak-torque). Use this limiting
[300]
Å@ function when 300% torque may cause the trouble to the
Å@ machine.
