/P-TL signal is used to externally limit the forward torque, and /N-TL
signal is used to externally limit the reverse torque. These external
torque limits have priority over internal torque limits. Internal limits
are used to retrain the maximum value of the motor’s operating torque
(or output torque) within a fixed range so that the load system or
operation targets can be protected.
Usual range of the motor’s available torque is as follows.
Depending on the type of a motor, Instantaneous maximum torque
can be 300% or less. If the torque limit is set higher than the maximum
allowed torque of the motor, the limit will be set at the Instantaneous
maximum torque of the motor and the preset limit will be ignored.
Please set SEt-14 and SEt-15 to limit the torque in
case of an overtravel. Setting range
0 to 300%, 300.
Internal torque limit is always effective. Therefore, if the external
torque limit and the torque limit to prohibit revolution are bigger than
the preset value for limiting internal torque, the external torque limit
and the torque limit to prohibit revolution become meaningless.
The status where torque is limited by the preset values can be
displayed to the controller by using /T-LMT signal. If the motor’s torque
is the same as the preset torque limit, /T-LMT signal will be displayed.
If the third digit of SEt-44 is 0, the motor will stop
by the torque set at SEt-14 and SEt-15, and if it is 1,
the servo will be OFF.
