7-3-6 Torque Bias Function
Commanded torque bias value can be monitored on the [FA-16] torque bias monitor.
In the case of [Ad-11] = 07, the setting can be changed on the [FA-16] monitor.
The torque command monitor (after calculation) [dA-15] displays the value with torque bias added to
the current torque command.
To calculate the motor rated torque (100%) in this function, use the following formula.
Motor rated torque = 79.58 × Motor capacity × Number of poles/Base frequency
Example: Motor rated torque = 79.58 × 5.5 (kW) × 4 (P)/50 (Hz) ≈ 35 Nm
