1. Set dA-04 in USr-08 using the operator with SERVO OFF (motor is
stopped). DA output is 0 Volt.
2. Measure output voltage of each channel.
3. Set SEt-71 and SEt-73 according to the calculation below.
When increasing the setting value with standard of 100, D/A output
voltage rises in + voltage and when decreasing the setting value, it
declines to - voltage. An accurate computation is as follows.
SEt-71 = 100 - Measured Output Voltage [mV] of channel 1*0.1
(Output voltage measured in servo OFF status)
SEt-73 = 100 - Measured Output Voltage [mV] of channel 2*0.1
(Output voltage measured in servo OFF status)
4. Or, as observing the output voltage, SEt-71 and SEt-73 can be set so
the voltage is 0[V]. Reduce the setting if the voltage is greater than
0[V], and increase the setting if the voltage is less than 0[V].

Factory setting is appropriate. It cannot be initialized even
if initialized with USr-09.
When error 80 (Check Sum Error) occurs, it is initialized to
initial setting in Table 4.4.
