3.1.6 Deviation-counter Clear Signal (DCLR)
This signal is used to clear the deviation counter.
Function
If a deviation generates while the TL signal is ON, this signal can be used to clear the deviation.
Caution: The actuator will operate if a pulse train is input while the DCLR signal is ON. If DCLR is used, turn this
signal ON only when the deviation counter is cleared.
 Related parameter
The deviation counter clear signal (DCLR) can be disabled using parameter No. 60.
3.1.7 Brake Forced-release Signal (BKRL)
As long as the controller is receiving the 24-V brake power externally for the controlled actuator equipped with an
electromagnetic brake, turning this signal ON while the servo is off will forcibly release the electromagnetic brake.
Caution: If the actuator is used in a vertical application, exercise caution when using this signal, because
turning off the servo while the brake release signal is ON will cause the actuator to drop.
3.1.8 Operating Mode (RMOD)
This signal is used to switch the operation mode between AUTO and MANU.
Function
This signal switches the internal operating modes of the controller while the MODE switch on the controller is set
to AUTO.
Turning this signal OFF will switch the controller to the AUTO mode, while turning it ON will switch the controller
to the MANU mode.
If the MODE switch is set to MANU, the internal mode of the controller will remain MANU regardless of the state
of this signal.
Caution: Once the operating mode switches to MANU, PIO activation will be inhibited. If a tool is connected,
however, the PIO activation permission/inhibition setting and safety speed enable/disable setting will
follow the selections made for the tool.
In the AUTO mode, the settings selected for the tool are disabled.
If PIO activation is permitted (monitor mode) in the AUTO mode or MANU mode, actuator operation
commands and parameter write commands from the tool are inhibited (limited by the tool).
 The operating mode signal (RMOD) can be disabled using parameter No. 41.
