2 PREPARATION 2-1 Initialize Operation This lens has a built-in encoder for a position sensor of zoom, iris and focus, and enables high-accuracy control and advanced for virtual interface. The correct position must be detected for these functions to operate correctly. The ON [Auto]/OFF [Manual] setting of initialization can be set from the information display. ON [Auto] OFF [Manual] The lens is automatically initialized on power-up. (When in servo mode) After the power is turned on, position detection is performed when the lens passes the specific position (normally near the center) in the course of lens operation. * Default setting at factory: OFF For the detailed setting method, refer to the "Display Operation Manual" at the end of this Operation Manual. How to detect the position of ZOOM Initialize operation How to detect the position When the power is turned on, the lens automatically ON (Auto) detects the position. Then, it returns to the position where it used to be when the power was turned on. Immediately after the power is turned on, the lens OFF (Manual) operates at a temporary position, and the position is corrected when the lens passes the specific position and the position is detected. How to detect the position of FOCUS Initialize operation Demand How to detect the position When the power is turned on, the lens Connected automatically detects the position. Then, it returns to the position instructed by ON (Auto) command from the demand. When the power is turned on, the lens Not automatically detects the position. Then, it connected returns to the position where it used to be when the power was turned on. When the power is turned on, the lens Connected automatically detects the position. Then, it returns to the position instructed by command from the demand. OFF (Manual) The lens does not automatically detect the position when the demand is Not not connected. When the demand is connected connected, the lens automatically detects the position. Then, it returns to the position instructed by command from the demand. • During initialization, lens operation is disabled. After initialization is completed, the lens returns to the position where it used to be before initialization. However, if the lens is operated in the position servo mode, the lens moves to the currently controlled position. • The initialization operation can be enabled/disabled on the information display. When any initialization operation is changed, turn off then on the power for the changes to take effect. The "Initialize Error!" message appears when the servo module is not mounted correctly, the lens is forcibly locked, or some other reason. In such case, check the lens condition, clear the problem, and then turn off and on the power again. Initialize Error! message Initialize Error! When position detection is failed: • The position signal sent from the lens to the camera and its indication on the information display will be incorrect. Notes • Iris is always initialized when powered on regardless of auto mode or manual mode. E8

2 PREPARATION
2-1 Initialize Operation
This lens has a built-in encoder for a position sensor of
zoom, iris and focus, and enables high-accuracy control and
advanced for virtual interface. The correct position must be
detected for these functions to operate correctly.
The ON [Auto]/OFF [Manual] setting of initialization can be
set from the information display.
ON [Auto]
The lens is automatically initialized on power-up.
(When in servo mode)
OFF [Manual]
After the power is turned on, position detection is
performed when the lens passes the specific position
(normally near the center) in the course of lens
operation.
* Default setting at factory: OFF
For the detailed setting method, refer to the “
Display
Operation Manual
” at the end of this Operation Manual.

How to detect the position
ON (Auto)
When the power is turned on, the lens automatically
detects the position. Then, it returns to the position
where it used to be when the power was turned on.
OFF (Manual)
Immediately after the power is turned on, the lens
operates at a temporary position, and the position is
corrected when the lens passes the specific position
and the position is detected.

When position detection is failed:
•
The position signal sent from the lens to the camera and
its indication on the information display will be incorrect.
Notes
•
Iris is always initialized when powered on regardless of
auto mode or manual mode.
•
During initialization, lens operation is disabled. After

The “Initialize Error!” message appears
when the servo
module is not mounted correctly
, the lens is forcibly
locked, or some other reason.
In such case, check the lens condition, clear the problem,
and then turn off and on the power again.
