7.7 Selecting Torque Limits
You can limit the torque that is output by the Servomotor.
There are four different ways to limit the torque. These are described in the following table.
Note: If you set a value that exceeds the maximum torque of the Servomotor, the torque will be limited to the maxi-
mum torque of the Servomotor.
7.7.1 Internal Torque Limits
If you use internal torque limits, the maximum output torque will always be limited to the speci-
fied forward torque limit (Pn402) and reverse torque limit (Pn403).
•
Rotary Servomotors
*
Set a percentage of the rated motor torque.
Note: If the setting of Pn402 or Pn403 is too low, the torque may be insufficient for acceleration or deceleration of
the Servomotor.
Limit Method Outline Control Method Reference
Internal Torque Limits
The torque is always limited with the setting
of a parameter.
Speed control,
position control, or
torque control
7.7.1
External Torque Limits
The torque is limited with an input signal
from the host computer.
7.7.2
Limiting Torque with
controlword (6040h)
A command from the Controller enables the
torque limit that is set in a parameter.
Speed control or
position control
15.6
Limiting Torque with
positive torque limit value
(60E0h) and negative
torque limit value
(60E1h)
Torque is controlled with torque limits from
the Controller.
