Function
Selection Bit 9 Σ-II series
Servopack
selection 1 Set this bit to 1 to enable the processing for Σ-II series
SERVOPACK.
0: Use
Σ-I series SERVOPACK.
1: Use Σ-II series SERVOPACK.
Bits 12
to 15 Error detection
coefficient 0
(default)
Change the setting if a position error occurs when using a
high-resolution encoder.
Position error will be checked by comparing the position
with the value of the setting parameter OW 0F (Error
Count Alarm Detection Setting) mutiplied by 2
n (n: Error
detection coefficient).
No. Name Setting Description
9 Number of Feedvack Pulses per
Rotation (For High-resolution) (No. of
encoder
pulses)
Set the number of encoder pulses before multiplication.
14 Additional
Function
Selection bit 9 Number of
encoder pulses
setting selection 1 Set this bit to 1 to enable the fixed parameter No. 9.
0: Enables the fixed parameter No. 8.
1: Enables the fixed parameter No. 9.
