18. TORQUE AND POWER GROUP "T".
TP1 Os (S126) TorqueThresholdTx
Function: Torque threshold set by the used to activate logic mark TV10.
Units: Fraction of the rated motor torque.
Valid values: 0..100% (it depends on the Driver connected)
Default value: 5%
TP2 Os (S158) PowerThresholdPx
Function: Power threshold set by the user to activate logic mark TV60.
This value is given as a fraction of the motor power.
The power of the motor is:
On a synchronous FXM motor = the product of three elements:
MP2 -F1200- MotorTorqueConstant
MP3 -S111- MotorContinuousStallCurrent
SP12 -F1600- MotorRatedSpeed
On an asynchronous SPM motor =
MP12 -F1208- MotorNominalPower
Units: Fraction of the rated (nominal) motor power.
Valid values: 1..100%
Default value: 5%
TP85 O (S85) TorquePolarityParameter
Función: This parameter is used to switch polarities of reported torque data for specific
applications. Polarities are not switched internally but externally (on the input and
output) of a closed loop system. The motor shaft turns clockwise when there is a
positive torque command difference and no inversion is programmed. This
parameter cannot be used to solve the positive feedback problem originated
because the 2nd feedback counts in the opposite direction (motor run away). This
case is only solved using parameter PP115 -S115- PositionFeedback2Type.
Version: Operative from version 04.01 on.

15 (MSB) - 3 (reserved)
2, Torque feedback value
= 0 non-inverted
= 1 inverted

0 (LSB) Torque command value
= 0 non-inverted
= 1 inverted
TV1 s (S80) TorqueCommand
TV2 s (S84) TorqueFeedback
Function: Display of the torque command/feedback value. They are transferred from the drive to
the control unit.
Valid values: -1000..1000 Nm.
TV3 s (F1701) TorqueFeedbackPercentage
Function: Instantaneous display of the percentage of power used with respect to the maximum
available at that velocity and servo drive system (Motor, Drive, current limit)
Valid values: 0..1000 º/oo
Version: Operational from version 02.03 on
TV10 (S333) TGreaterTx
Function: Logic mark to indicate that the Torque (TV2) is greater than the TorqueThresholdTx
(TP1). See TP1.
Valid values: 0, TV2 < TP1
1, TV2 > TP1
