【#3022(PR)】 sgear Encoder gear ratio
Set the gear ratio of the spindle to the encoder.
Setting value 0 ---> Detector : Spindle = 1:1
Setting value 1 ---> Detector : Spindle = 1:2
Setting value 2 ---> Detector : Spindle = 1:4
Setting value 3 ---> Detector : Spindle = 1:8
This parameter is enabled only when "S-analog" is set by the spindle connection parameter "#3024
sout".
---Setting range---
0 to 3
【#3023】 smini Minimum rotation speed
Set the minimum spindle speed.
If an S command below this setting is issued, the spindle will rotate at the minimum speed set by this
parameter.
---Setting range---
0 to 32767 (r/min)
【#3024(PR)】 sout Spindle connection
Select the type of spindle to connect.
0: Dedicated optical communication network (Test mode)
1: Dedicated optical communication network
2 - 5: Analog connection (Not used)
(Note 1) The setting of "#3031 smcp_no" is also necessary on the test mode and the spindle is
(Note 2) When the spindle to be used as the spindle/C axis is set to the test mode, set "1" to "#2018
---Setting range---
0 to 5
【#3025】 enc-on Spindle encoder
Set the connection specifications of a spindle's encoder.
0: Without encoder feedback when using analog spindle and connecting to NC
1: With encoder feedback when using analog spindle and connecting to NC
2: Mitsubishi spindle drive unit
---Setting range---
0 to 2
【#3026】 cs_ori Selection of winding in orientation mode
Select the coil control in orientation mode for the spindle motor which performs coil changeover.
0: Perform coil changeover based on the command from NC. (depending on the setting of
1: Use the coil L
【#3027】 cs_syn Selection of winding in spindle synchronization control mode
Select the coil control in spindle synchronization control mode for the spindle motor which performs
coil changeover.
0: Perform coil changeover based on the command from NC. (depending on the setting of
1: Use the coil H
Set it when a spindle drive is not connected. In this mode, the alarm for drive units not mounted
will not occur even when no spindle drive unit is connected.
included in the maximum number of spindles and control axes.
no_srv" for the C axis.
Without the setting, the error indicating that the C axis is not mounted will occur.
In this case, do not set the servo ON for the C axis. When the servo is set ON for the C axis, all
the subsequent axes cannot be set as servo ON (cannot be operated as a C axis).
To test commands for the C axis, set the parameter for NC axis instead of the spindle/C axis.
(In this case, allocate another number available to "#1021 mcp_no".)
