■Temperature control modules (for the R60TCTRT2TT2)
1.
Set Stop (0) in 'PID continuation flag' (Un\G306) of all the channels with an external device (such as a GOT).
2.
Turn on and off 'Setting/operation mode command' (Y1).
3.
Turn off all the Y signals.
4.
Check that the PID control is stopped with 'Setting/operation mode status' (X1).
To replace other temperature control modules, also stop the PID control as above. For details on the I/O signals and buffer
memory areas of each temperature control module, refer to the User's Manual (Application) for the temperature control
module used.
■Simple motion modules (for the RD77MS16)
1.
Stop the operations of all the axes.
2.
Turn off all the Y signals.
To replace other simple motion modules, also stop the control as above. For details on the I/O signals and buffer memory
areas of each simple motion module, refer to the User's Manual (Application) for the simple motion module used.
■High-speed counter modules (for the RD62P2)
1.
Turn off 'CH1 Count enable command (Y4)' and 'CH2 Count enable command (YC)' with an external device (such as a
GOT).
2.
Turn off 'CH1 PWM output start command (Y6)' and 'CH2 PWM output start command (YE)' when the PWM output
function is used.
3.
Turn off all the Y signals.
To replace other high-speed counter modules, also stop the control as above. For details on the I/O signals and buffer
memory areas of each high-speed counter module, refer to the User's Manual (Application) for the high-speed counter
module used.
■Flexible high-speed I/O control modules (for the RD40PD01)
1.
Turn on 'Hardware logic control stop request' (Y5). Or perform [Online]  [Module operation]  [Hardware logic control
Stop] from the configuration tool.
2.
Turn off all the Y signals.
■Positioning modules (for the RD75P4)
1.
Stop the positioning control of the positioning module with external stop signals or axis stop signals [Y4, Y5, Y6, and Y7]
of each axis.
2.
Configure settings in external devices so that the devices do not malfunction.
3.
Turn off all the Y signals.
To replace other positioning modules, also stop the control as above. For details on the I/O signals and buffer memory areas
of each positioning module, refer to the User's Manual (Application) for the positioning module used.
