II - 86
【#3020】 stapt 4 Synchronous tapping 1st step acceleration/deceleration time constant
(Gear: 11)
Set the time constant for synchronous tapping 1st step linear acceleration/deceleration
control when gear 11 is selected. (linear acceleration/deceleration pattern)
---Setting range---
1 to 5000 (ms)
【#3021】
Not used. Set to "0".
【#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)
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.
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 included in the maximum number of spindles and control axes.
(Note 2) When the spindle to be used as the spindle/C axis is set to the test mode, set "1"
to "#2018 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".)
---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 parameter #1239/bit0)
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 parameter #1239/bit0)
1: Use the coil H
【#3028】 sprcmm Tap cycle spindle forward run/reverse run M command (L system only)
Set the M codes for the spindle forward run/reverse run commands during asynchronous
tapping.
High-order 3 digits: Set the M code for spindle forward run command.
Low-order 3 digits: Set the M code for spindle reverse run command.
When "0" is set, the M code for spindle forward run command is handled as "3" and the M
code for spindle reverse run command as "4".
---Setting range---
0 to 999999
【#3029】 tapsel
Not used. Set to "0".
