Settings of MEXE02
9.3.2 Limiting the setting range of the torque limiting value

"Torque limiting maximum value" parameter
The setting range of the torque limiting 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 setting error (INFO-TRQ-DE) information is generated.
9.3.3 Setting the rotation speed and torque limiting value using PWM signal

"External setting method" parameter
The rotation speed and torque limiting value can be set by inputting the PWM signal.
The rotation speed or torque limiting value changes according to the duty cycle of input PWM signal.
