torque limit
The torque limit source is switched over
based on the setting of H07-07.
H07-07 = 1:
Valid: External forward torque limit enabled
Invalid: Internal forward torque limit enabled
H07-07 = 3 and AI limit larger than external
forward limit:
Valid: External forward torque limit enabled
Invalid: AI torque limit enabled
H07-07 = 4:
Valid: AI torque limit enabled
Invalid: Internal forward torque limit valid
It is
recommended
that the
logic of the
corresponding
terminal be set
to level valid.
FunIN.17 N-CL
External
reverse
torque limit
The torque limit source is switched over
based on the setting of H07-07.
H07-07 = 1:
Valid: External reverse torque limit enabled
Invalid: Internal reverse torque limit enabled
H07-07 = 3 and AI limit smaller than external
reverse limit:
Valid: External reverse torque limit enabled
Invalid: AI torque limit enabled
H07-07 = 4:
Valid: AI torque limit enabled
Invalid: Internal reverse torque limit valid
It is
recommended
that the
logic of the
corresponding
terminal be set
to level valid.
When the output torque is limited, the DO terminal outputs the C-LT signal described in the
following table.
