Scaling Factor (Scaling)
When the MTR Configuration Is Set to Single Motor (revolution signal: pulse), Single
Motor (revolution signal: analog), or Double Motor
Setting the Scaling Factor for Scaling the Revolution Signal
You can set the factor for scaling the revolution signal. Set the factor to a value from 0.0001 to 99999.9999.
• When the Revolution Signal Type is Analog
This setting is used as the scaling factor in the equation for the
linear scaling of analog input
• • When the Revolution Signal Type is Pulse
This setting is used as the scaling factor in the equation for the number of
Setting the Scaling Factor for Scaling the Torque Signal
You can set the factor for scaling the torque signal to motor torque. Set the factor to a value from 0.0001 to
99999.9999.
• When the Torque Signal Type is Analog
This setting is used as the scaling factor in the equation for the
linear scaling of analog input
• When the Torque Signal Type is Pulse
This setting is used as the scaling factor in the equation for the
.
Setting the Scaling Factor for Computing the Motor Output
You can specify the scaling factor for computing the motor output (mechanical power) from the rotating speed
and torque. Set the factor to a value from 0.0001 to 99999.9999.
The equation is indicated below. The scaling factors of the rotating speed and torque are set so that the unit of
the rotating speed is min
–1
(or rpm) and the unit of torque is N•m. When the scaling factor of the motor output
specified here is 1, the unit of the motor output Pm is W. Because the
of Pm, we recommend that you set the scaling factor of each item so that the unit of Pm is W.

Motor output Pm =
×Speed×Torque×S
Speed: The rotating speed, determined from the number of pulses per revolution
Torque: The torque, determined from the torque signal pulse rating
S: The scaling factor
When the MTR Configuration Is Set to Auxiliary Input (Aux)
You can set the factor for scaling the auxiliary signal. Set the factor to a value from 0.0001 to 99999.9999.
This setting is used as the scaling factor in the equation for the linear scaling of analog input.
