461. Encoder Multiplication Factor, X-axis.
462. Encoder Multiplication Factor, Y-axis.
463. Encoder Multiplication Factor, Z-axis.
464. Encoder Multiplication Factor, A-axis.
465. Encoder Multiplication Factor, B-axis.
466. Encoder Multiplication Factor, C-axis.
467. Encoder Multiplication Factor, U-axis.
468. Encoder Multiplication Factor, V-axis.
469. Encoder Multiplication Factor, W-axis.
Format (Default=4)
Only one the following 3 numbers:
Setting = 1, Encoder pulse number is multiplied by 1.
Setting = 2, Encoder pulse number is multiplied by 2.
Setting = 4, Encoder pulse number is multiplied by 4.
Note:
The setting of multiplication is highly relative with machine’s rigidity. If a motor
divergence occurs too heavily, it means that the rigidity is too big. And then it can be
improved by lowering the multiplication.
Ex: If factor = 2 for MCM #161 and the encoder resolution is 2000 pulses/rev,
then the feed-back signals = 2000 * 2 = 4000 pulses/rev for Y-axis.
