When this terminal is reset, the torque limit setting is disabled and the inverter uses the maximum
value (300%) as the torque limit value.
When the torque limit enabled (TL) function is not allocated to a multifunction input terminal, the tor-
que limit function is enabled at all times.
• The torque limit function regards the motor rated torque as 100%.
• When “132: TRQ (T
orque limited)” is set to Output Terminal [DO1] Function Selection (E20), Output
Terminal [DO2] Function Selection (E21) or Output Terminal [ROA, ROB] Function Selection (E27),
the torque limit function can be checked to see if it is activated by the status of the torque limited
signal.
• To enable the torque limit value by analog input or current input, set “7: Analog torque limiter” to one
of Input Terminal [AI1] Function Selection (E61), Input Terminal [AI2] Function Selection（AII）
(E62) or Input Terminal [AI2] Function Selection（AIV） (E63). Analog inputs 0 to 10 V or 4 to 20
mA (0 to 20 mA) are equivalent to torque limit values 0% to 300%. The torque limit value set by
analog input is enabled in all operation modes.
