No.
Name
Functions
1
Protection when Enable Off → ON
(*1)
Prevents unstable operation when Enable OFF → ON
(Controls swing angle within ±10° when Enable OFF →
ON)
2
Protection when Power Off
Prevents unstable operation when Power ON → OFF
(Controls swing angle within ±10° when Power ON →
OFF)
3
Power IC Overheating Protection
(*2)
Stops supplying power (shut down) to the scanner when
the internal temperature of the Power IC is over
Typ.160°C (surface temperature: Typ.130°C) and prevents
further overheating.
As the temperature of the Power IC decreases and falls
below the threshold, the power is supplied again (auto
return).
*1 Please do not turn the power on when Enable is on.
*2 The Power IC Overheating Protection is to protect against damage due to the heat from the driver.
Intermittent instability may occur during beginning of shutdown and auto return.
Refer to Overheat Alarm Output (4-6-6) to form the sequence configuration of Enable OFF before
operating the Power IC Overheating Protection.
