No. 34 (Rotary Motor)
Rated Motor Speed Setting Range Setting Unit Default Value
1 to 32000 min
−1 3000
Description
Set the rated motor speed in 1 min −1 units.
Set this parameter based on the specifications of the motor that is used.
No.34 (Linear Motor)
Rated Speed
Setting Range Setting Unit Default Value
1 to 32000
0.1m/s,
0.1mm/s
3000
Description
Set the rated speed.
Set the rated speed in accordance with the specifications of the linear servomotor to be used.
Refer to 6.1.8 Linear Scale Pitch and Rated Motor Speed on page 6-15 for details.
No. 36 (Rotary Motor)
Number of Pulses per Motor Rotation Setting Range Setting Unit Default Value
1 to 2 31 −1 pulse 16384
Description
Set the number of feedback pulses per motor rotation.
Set the value before multiplication to match the specifications of the motor used.
(For example, if a 16-bit encoder is used, set 2
14 = 16384.)
When using the SVA-01 Module in combination with a SGDM, SGDH, SGDS, or SGDV SERVOPACK, set the value in
accordance with the SERVOPACK PG dividing ratio: Parameter Pn201 or Pn212 for SGDM, Pn201 for SGDH, and
Pn212 for SGDS and SGDV SERVOPACKs.
No.36 (Linear Motor)
Number of Pulses per Linear Scale Pitch
Setting Range Setting Unit Default Value
1 to 2 31 -1
pulses/scale
pitch
65536
Description
Set the number of pulses equivalent to the value set for No.6 :Linear Scale Pitch.
Set the value in accordance with the specifications of the linear motor to be used.
Refer to 6.1.8 Linear Scale Pitch and Rated Motor Speed on page 6-15 for details.
No. 38
Maximum Number of Absolute Encoder Turns Rotation Setting Range Setting Unit Default Value
1 to 2 31 −1 revs 65534
Description
Set the maximum number of rotations for the absolute encoder to the highest number that the encoder can man-
age.
Set this parameter to match the settings of the encoder being used.
• Σ-I series: Set to 99999 (fixed).
• Σ-II, Σ-III, or Σ-V Series: Set to the same value as the multiturn limit in the SERVOPACK.
<Example>
For axes set as infinite axes (bit 0 of fixed parameter Function Selection Flag 1 set to 1), set to 65534 max. (same value as
Pn205).
This parameter is used to manage position information when an absolute encoder is used as an infinite length axis.
No. 42
Feedback Speed Movement Averaging Time Constant Setting Range Setting Unit Default Value
0 to 32 ms 10
Description
Set the moving average time constant for the feedback speed.
The feedback speed is obtained by converting the unit of the difference between feedback pulse inputs in one control
cycle and the next control cycle. To avoid the scattering of the values caused by quantization error, a moving average can
be applied to the calculation of feedback speed.
In the parameter Feedback Speed (monitoring parameter IL
40), the value obtained by applying the moving average
for the time constant set in this parameter to the feedback position of each scan is stored.
