When “00” is specified for the torque
limit selection (b040), the torque limits 1
to 4 apply as shown to the top right.
When “00” is specified for the torque
limit selection (b040), the torque limit 1
to 4 are set as shown to the bottom right.
The torque limit 1 to 4 are switched by
the torque limit switches 1 and 2
assigned to intelligent input terminals 7
and 8, respectively for example:
When applying the torque limit function
to the motor operation at low speed, also
use the overload restriction function to
get more stable performance.
