6.8 How to use Monitor
The servo's internal speed command and torque, and the feedback motor speed can be monitored
from outside through the analog output (MONIT1) and (MONIT2). The range of output voltage is -
4[V] - 4[V]. The following are the parameters related to the use of the motor

In case that observation in difficult because analog output value is small, it is to see that variable
multiply pertinent multiple.
For example, in case of input 3, variable size enlarges three times.

This is used to output values by applying appropriate offset to the analog output values. This is to
enable adjustment of the values output on 0[V] potential by applying offset to the monitor output.
Unit used is [%], and the maximum value is 100 [%]. If the speed is output assuming the
maximum speed as being 5000[rpm], 1000[rpm], 20[%] of 5,000, is displayed on 0[V] when offset
20 is loaded.
Monitor outputs according to the parameter set values are as follows. As the method of using
monitor 1 and monitor 2 is the same, the following figures show outputs of monitor 1 only.
