What is the difference between tLIN and tLIG parameter setting in Altivar 32 drive.

tLIM permit to limit the torque when the motor is in motoring mode and tLIG permit to limit the torque when the motor is in generator mode.
So, these functions permit to limit the motor available torque,for example in case of motor mode, if torque need by application increased more
than the limit ,then the speed will decrease and the torque does not exceed the limit,and not to stop the motor when the limit is reached.

Note:
tLIM means Motoring torque limit
tLIG means Generator torque limit
