[Md.300] Servo input axis position value
The position value for the servo input axis is stored in servo input axis position units (Page 29 Servo input axis position
units) as follows.
The position value for the servo input axis is the value after processing the smoothing, the phase compensation and the
rotation direction restriction.
Setting value of "[Pr.300] Servo input axis type"
1: Command position value
2: Actual position value
3: Servo command value
4: Feedback value
[Md.301] Servo input axis speed
The speed for the servo input axis is stored in servo input axis speed units (Page 29 Servo input axis speed units).
The speed for the servo input axis is the value after processing smoothing, phase compensation, and rotation direction
restriction.
[Md.302] Servo input axis phase compensation amount
The phase compensation amount for a servo input axis is stored in servo input axis position units (Page 29 Servo input
axis position units).
The phase compensation amount for a servo input axis is the value after processing smoothing and phase compensation.
Storage details
• The position value for the servo input axis
is stored.
Refresh cycle: Operation cycle
• The speed for the servo input axis is
stored.
Refresh cycle: Operation cycle
• The current phase compensation amount
is stored.
Refresh cycle: Operation cycle
• While the rotation direction is restricted,
the accumulation for the input movement
amount in the opposite direction of the
enabled direction is stored.
Refresh cycle: Operation cycle
Storage details
• The accumulative position value started with "[Md.20] Command position value"/
"[Md.101] Actual position 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] Command position value"/"[Md.101] Actual position value" is
changed by the home position return or the current value change, the value is changed
to the new current value.
• When the absolute position detection system setting is invalid, the accumulative
position value that starts from 0 for the connected servo amplifier is stored.
• When the absolute position detection system setting is valid, the accumulative position
value that starts from the absolute position command/encoder feedback pulse for the
connected servo amplifier is stored.
• The servo input axis position value will not change, even if the home position return or
the current value is changed.
