Setting the unit of motor output
3.
Turn the jog shuttle to select [Unit] under Pm.
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 compute the motor output (mechanical
power) from the rotating speed and torque. Select the value in the range from 0.0001
to 99999.9999. The equation is indicated below. When the scaling factor is “1” in the
following equation, the normal motor output is determined.
*1 Torque derived in section 15.5.
*2 Rotating speed derived in section 15.4.

Setting the unit of motor output
• Number of characters
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.
