Note: The maximum setting for the encoder output resolution is 4,096.
If the resolution of the external encoder exceeds 4,096, pulse output will no longer be possible at the resolu-
tion given in
 Feedback Resolution of Linear Encoder on page 5-45.
10.3.5 External Absolute Encoder Data Reception Sequence
Refer to the following section for details.
6.9.4 Reading the Position Data from the Absolute Linear Encoder on page 6-44
With fully-closed loop control, the same sequence as for a Linear Servomotor is used.
10.3.6 Electronic Gear Setting
Refer to the following section for details.
5.15 Electronic Gear Settings on page 5-42
With fully-closed loop control, the same setting as for a Linear Servomotor is used.
If the setting is 20 and the speed is 1,600 mm/s, the output frequency would be 1.6 Mpps
= 1,600,000 = 1.6 Mpps
Because 1.6 Mpps is less than 6.4 Mpps, this setting can be used.
