3-6-13 Torque Limit Function

The automatic user parameter setting function allows you to make the inverter
automatically record changed function codes in  to . You can use the
stored function codes as a history of data change. To enable this function,
select "" (enabling automatic user parameter setting) for the .
When any data is changed and
stored in  to  sequentially.
The latest data is in , and the oldest one is in .
Stored function codes in  to  are not duplicated. If duplicated func-
tion code is changed, old existing function code is deleted. If number of
changed function code exceeds 32, the oldest one in  is deleted.

Torque limit function allows you to limit the motor output when 03 (SLV) is set
for the V/F characteristics set at parameter . You can select one of the fol-
lowing modes with the torque limit selection ().
1. Quadrant-specific setting mode (=)
In this mode, individual torque limit value to be applied to four quadrants (i.e.
forward powering, reverse regeneration, reverse powering and forward regen-
eration) are set as the torque limits 1 to 4 ( to ), respectively.
2. Terminal-switching mode(=)
In this mode, the torque limit values set in the torque limits 1 to 4 ( to
) are switched from one another according to the combination of the
states of torque limit switch terminals 1 and 2 (TRQ1 and TRQ2) assigned to
intelligent input terminals. A single selected torque limit is valid in all the oper-
ating states.
3. Analog voltage input mode(=)
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 " (TL: whether to enable torque limitation)" has been assigned
to any intelligent input terminal, the torque limit mode selected by the setting
of  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  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.
