Parameter
Speed lower limit
Set the lower limit value of the rotation speed with the "Speed lower limit" parameter.
If the rotation speed below the "Speed lower limit" is already set in the operation data, the rotation speed is limited to
the value set in the "Speed lower limit" parameter.
Setting example: When 500 r/min is set in the "Speed lower limit" parameter while the setting method of the
rotation speed is external DC voltage.

: Rotation speed setting error information
When the rotation speed being operated is limited to the value set in the "Speed upper limit" parameter or the
"Speed lower limit" parameter, the rotation speed setting error (INFO-SPD-DE) information is generated.
A speed lower than 80 r/min (0 to 79 r/min) is excluded from the speed limitation of the "Speed lower limit" parameter.
(Digital setting, external analog setting device, PWM signal input)
If a negative value is set with the "External analog operation speed command oset" parameter, the motor will not
start rotating until the command value is 80 r/min or higher.

Torque limiting maximum value
The setting range of the torque limiting value is set to 0 to 200% at the time of shipment.
Set when the upper limit is provided.
If the torque limiting value exceeding the "Torque limiting maximum value" is already set in the operation data, the
torque limiting value is limited to the value set in the "Torque limiting maximum value" parameter.
When the torque is limited to the torque limiting value set in the "Torque limiting maximum value" parameter, the
torque limiting value setting error (INFO-TRQ-DE) information is generated.
Setting example: When 160% is set in the "Torque limiting maximum value" parameter while the setting method of
the torque limiting value is external DC voltage.

Note
If the torque limiting function is disabled, the maximum value of the output torque is the peak torque (200%) not the
value set in the "Torque limiting maximum value" parameter. Also, the torque limiting value setting error information
is not generated.
