"B" Group: Fine Tuning Functions Section 3-6
3. Analog voltage input mode(b040=02)
In this mode, the torque limit value is set by a voltage applied to the control cir-
cuit terminal O. The voltage range 0 to 10V corresponds to the torque limit
value range 0 to 200%. A single selected torque limit is valid in all the operat-
ing states.
If parameter "40 (TL: whether to enable torque limitation)" has been assigned
to any intelligent input terminal, the torque limit mode selected by the setting
of b040 is enabled only when the TL terminal is turned ON. When the TL ter-
minal is turned OFF, torque limit settings are invalid, and the maximum torque
setting is applied as a torque limit.
It the TL function has not been assigned to the intelligent input terminal, the
torque limit mode selected by the setting of b040 is always enabled.
Each torque limit value used for this function is expressed as a ratio of the
maximum torque generated when the inverter outputs its maximum current on
the assumption that the maximum torque is 200%.
Note that each torque limit value does not represent an absolute value of
torque. The actual output torque varies depending on the motor.
It the torque limited signal function (TRQ) is assigned to an intelligent output
terminal, the TRQ signal will turn ON when the torque limit function operates.
100% torque is referred to inverter rated current. Absolute torque value is up
the motor to be combined.
