7.5.1.4 Torque limiting via TQ-LMT input (same limit value for forward and reverse
directions)
When P1-10 =3, the forward and reverse torque limit is determined by the logic state of the torque limit
input TQ-LMT.
◆
Users will need to congure the logic of the TQ-LMIT input according to their application (normally open/
closed). However, when the primary TQ-LMT logic state is established (valid), forward and reverse torque
limits are dened by P1-06. If the primary TQ-LMT logic state is not established (invalid), forward and reverse
torque limits are dened by P1-25.

When P1-10 = 3 and the TQ-LMT input is valid, the forward
and reverse torque limits are dened by P1-06.
When P1-10 = 3 and the TQ-LMT input is invalid, the forward and
reverse torque limits are dened by P1-25.
7.5.1.5 Torque limiting via TQ-LMT input (forward and reverse limits assigned di󰀨ering values)
When P1-10=5, the forward and reverse torque limits are determined by the logic state of the TQ-LMT input.
Users will need to congure the primary logic of the TQ-LMT beforehand (normally open/closed). Regardless
of which logic they choose, when the TQ-LMT input is valid or invalid, based on the selected logic, the
forward and reverse limits can be assigned di󰀨erent values from one another in each state of the TQ-LMT
input. This means users will have 2 possible limits in the forward direction and 2 possible limits in the reverse
direction.

When P1-10 = 5. The TQ-LMT torque limit input is invalid, the
motor output forward torque is limited to the set value of P1-06,
and the reverse torque is limited to the set value of P1-25.
