1: 0.1666 (ms)
3: 0.5 (ms)
6: 1.0 (ms)
Others (can be set only by the manufacturer and not by
the user)
▪ If the communication cycle is 0.0833 ms (Pr7.20=0),
please set an adaptive filter invalid. (Pr2.00=0)
and the pulse regeneration function is automatically
disabled.

[bit 0] specifies the data size of RTEX communication.
0: 16-byte mode
1: 32-byte mode
[bit 1] specifies the inter-axis sync mode when 2 or more
axes are used with TMG_CNT.
Set this parameter to 0 when not using
TMG_CNT.
0: Interaxis semi-synchronous mode
1: Interaxis full-synchronous mode
▪ For details, refer to 4-2-1-1.
[bit2] For manufacturer’s use.
Always set to 0
[bit3] For manufacturer’s use.
Always set to 0
Note:
Be sure to set communication cycle (Pr7.20) and command updating cycle (Pr7.21) of RTEX at same
frequency as in upper device. For function expansion setting of RTEX (Pr 7.22), be sure to set at same setting
in upper device. Otherwise performance is not assured.
2-5-3 Example of mode setup
C
ommunication period of 0.5 ms, command updating period 1.0 ms, 16-byte mode and interaxis semi-synchronous
mode
• Pr.7.20 = 3 (Communication cycle 0.5 ms)
• Pr.7.21 = 2 (Command updating cycle 1.0 ms = 0.5 ms 2)
• Pr.7.22 = 0 (16-byte mode and interaxis semi-synchronous mode)
In this example setting, CP/CV/CT control mode selection is necessary by specifying command code.
Note:
If matching condition of Pr.7.20 RTEX communication cycle setup and Pr.7.21 RTEX command updating
cycle setup is not established, Err.93.5 Parameter setup error protection 4 will be generated.
