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 (Torque limited)” is set to Output Terminal [DO1] Function Selection
(3005Hex-15Hex) or Output Terminal [ROA, ROB] Function Selection (3005Hex-1CHex), 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 voltage, set “7: Analog torque limiter” to Input Terminal
[AI1] Function Selection (3005Hex-3EHex). Analog inputs 0 to 10 V are equivalent to torque limit
values 0% to 300%. The torque limit value set by analog input is enabled in all operation modes.
