Setting Unit
Default Value
1 to 32000
min
−1
3000
Set this parameter based on the specifications of the motor that is being used.
Set the motor's rated speed in the appropriate units for a rotary motor or linear motor, as shown below.
Rotary motor units: min
−1
Linear motor units: 0.1 m/s
No. 36
Encoder Resolution in Pulses/Revolution (Rotary Motor) or
Encoder Output Resolution per Linear Scale Pitch (Linear Motor)
Setting Range
Setting Unit
Default Value
1 to 2
31
−1
Pulse
16384
Set this parameter based on the specifications of the motor that is being used.
For a rotary motor, set the number of feedback pulses per motor rotation.
Set the value before multiplication (by the input pulse multiplier) to match the specifications of the motor being used. (For a 16-
bit encoder, set 2
14
= 16384.)
When using a linear motor, set the value of the encoder output resolution per linear scale pitch before multiplication by the input
pulse multiplier.
For a rotary motor: 1 = 1 pulse/rev
For a linear motor: 1 = 1 pulse/linear scale pitch
No. 38
Max. Revolution of Absolute Encoder
Setting Range
Setting Unit
Default Value
1 to 2

−1
Rev
65536
Set the maximum number of rotations for the absolute encoder when an absolute encoder is being used.
Set this parameter to match the settings of the encoder being used.
•
Σ-series: Set to 99999 (fixed).
•
Σ-II or Σ-III Series: Set to the same value as the multiturn limit setting in the SERVOPACK.
For axes set as infinite axes (bit 0 of fixed parameter Function Selection 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 and an infinite length axis has been set.
(
Note) Set to 0 when a direct drive motor is being used.

10
Set the moving average time constant for the feedback speed.
The Feedback Speed (monitoring parameter IL40) is the moving average value calculated from each scan's feedback
position using this time constant.
