16. INDEXER POSITIONING OPERATION
(6) Electronic gear
Parameter
No. Symbol Name
Initial
value
Unit Setting range
PA06 *CMX Number of gears on machine-side 1 1 to 16384
PA07 *CDV Number of gears on servo motor-side 1 1 to 16384
CAUTION
False setting will result in unexpected fast rotation, causing injury.
POINT
This parameter is made valid when power is switched off, then on after
setting.
Set the electronic gear within the following condition range.
(1) 1/9999
CMX/CDV 9999
(2) CDV
STN 32767
(3) CMX
CDV 100000
When a value out of the condition range is set, the parameter error (A37)
occurs. If the setting of electronic gear ratio is small, the servo motor may not
operate with the set servo motor speed.
Setting range of the parameters No.PA06 and PA07 for the indexer
positioning operation is 1 to 16384. It is different from the setting range for the
point table positioning operation.
Use the parameters No. PA06 and PA07 to adjust the rotation amount “m” on the servo motor shaft that is
necessary to rotate the machine side “n” times. A setting example for electronic gear is shown next.
