Setting the unit of torque
3.
Turn the jog shuttle to select [Unit] under Torque(Ch8).
4.
Press the SELECT key. A keyboard appears.
5.
Use the keyboard to set the unit.
For keyboard operation, see section 4.1, “Entering Values and Strings.”
Explanation
Setting the scaling factor
You can specify the scaling factor used to transform the torque meter signal to the
torque of the motor. Select the value in the range from 0.0001 to 99999.9999. By
setting the torque per volt of input voltage, the torque is derived from the following
equation.
Torque = Scaling factor

Eight characters or less.
• Types of characters
Characters that are displayed on the keyboard or a space.
Note
•
To set the unit of the motor output that is determined in section 15.7 to “
Ω
,” set the unit of
torque to Nm.
•
When the unit of torque is set to “Nm” (see section 15.5), the motor output is determined in
terms of “
Ω
.” If the unit of torque is set to some other unit, the unit of motor output can be
converted to “
Ω
” by multiplying the conversion value in the table below.
