Figure 4.3.125 Roll-out operation
The relationship among Tref (torque reference), NLmt (speed limit) and N (motor speed)
is shown as below when used in winding operation and roll-out operation.

(6) Torque compensation setting (AI2 :04-07 and 04-08)
. Torque compensation is added to the torque for torque loss, mechanical damage or
other losses.
. Set the multi-function analog input AI2 as the input compensation of torque (04-05 =
16).
. Set appropriate signal level for the torque compensation. The torque compensation
is determined by the signal polarity, not by the direction of the operation command.
Tcomp is fixed as + voltage (or current), therefore it is the positive torque
compensation (the rotation of motor shaft is counterclockwise).
