[Cd.321] Synchronous encoder axis control method
Set the control method for the synchronous encoder axis.
Setting value Details
0: Current value change The synchronous encoder axis position value and the synchronous encoder axis position value per cycle are changed as
follows. Set the new position value in "[Cd.322] Synchronous encoder axis position value setting address".
[Md.320]
Synchronous encoder axis position
value
[Md.321]
Synchronous encoder axis position
value per cycle
1: Counter disable Input from the synchronous encoder is invalid. Smoothing processing, phase compensation processing and rotation direction
restriction processing are continued. While these processes are valid, the input axis speed may not stop immediately when the
counter disable is selected.
2: Counter enable Input from the synchronous encoder is enabled.
[Cd.322] Synchronous encoder axis position value setting address
Set a new current value in synchronous encoder axis position units to apply to the current value change for the synchronous
encoder axis (Page 56 Synchronous encoder axis position units).
[Cd.323] Synchronous encoder axis error reset
If set to "1", "[Md.326] Synchronous encoder axis error No." and "[Md.327] Synchronous encoder axis warning No." are set to
0 and then "b4: Error detection flag" and "b5: Warning detection flag" of "[Md.325] Synchronous encoder axis status" are
turned OFF. A synchronous encoder connection becomes valid if there is no error.
The Simple Motion module resets the value to "0" automatically after completion of the error reset.
However, the setting of the synchronous encoder axis will not be valid even if the error is reset for the setting error of the
synchronous encoder axis parameter. Reconfigure the parameter and turn the power supply ON again.
[Cd.324] Connection command of synchronous encoder via CPU
Use this data when "201: Synchronous encoder via CPU" is set in "[Pr.320] Synchronous encoder axis type".
If set to"1", the synchronous encoder axis is connected. Once connected, the synchronous encoder current value is restored
based on the "[Cd.325] Input value for synchronous encoder via CPU".
If set to "0", the synchronous encoder axis is disconnected.
[Cd.325] Input value for synchronous encoder via CPU
Use this data when "201: Synchronous encoder via CPU" is set in "[Pr.320] Synchronous encoder axis type".
Set a value to be used every time as the input value for the synchronous encoder in encoder pulse units.
If 1 or more is set in "[Pr.329] Resolution of synchronous encoder via CPU", it is processed as a cycle counter within the range
from 0 to (resolution of synchronous encoder via CPU - 1).
"[Cd.322] Synchronous encoder axis position value setting address"
A value that is converted "[Cd.322] Synchronous encoder axis position value setting
address" into the range from 0 to "[Pr.324] Synchronous encoder axis length per cycle -
1".
