[Md.300] Servo input axis current value
The current value for the servo input axis is stored in servo input axis position units (Refer
to Section 2.1.1) as follows.
The current value for the servo input axis is the value after processing the smoothing, the
phase compensation and the rotation direction restriction.

Storage details
1: Feed current value
2: Real current value
• The accumulative current value started with "[Md.20] Feed current
value"/"[Md.101] Real current value" for the connection to the servo amplifier is
stored. It is also stored in the range from -21474.83648 to 21474.83647 [degree]
for degree units.
• When the "[Md.20] Feed current value"/"[Md.101] Real current value" is changed
by an OPR or a current value change, the value is changed to the new current
value.
3: Servo command value
4: Feedback value
• When of the absolute position detection system setting is invalid, the
accumulative current value that starts from 0 for the connected servo amplifier is
stored.
• When of the absolute position detection system setting is valid, the accumulative
current value that starts from the absolute position command/encoder feedback
pulse for the connected servo amplifier is stored.
• The servo input axis current value will not change, even if an OPR or the current
value is changed.
