IRS-51.2”) to convert the detected position data to binary or gray codes for output. 1-1. Features (1) Superior durability NSD's original ABSOCODER is used as the position sensor which features a no-contact construction for excellent durability. (2) Compact design The unit's outside dimensions (39(W) x 155(H) x 93(D)) were miniaturized, and the shape of case is a bookshelf type. -
Page 9: Limitations
1-2. Limitations Important Cautions concerning power-off and error occurrence If the sensor moves while the converter power is OFF or when an error is present, it mightn’t detect accurate machine positions thereafter. The zero position setting should be done after turning ON the power supply or clearing the error. For setting details, refer to "8-7. -

Page 19: Ce Marking
5-3. CE Marking NCV-30 Series conforms to CE Marking (EMC directive), but stands outside scope of the low voltage directive because it is 24 VDC power apparatus. 5-3-1. EMC Directives It is necessary to do CE marking in the customer’s responsibility in the state of a final product. Confirm EMC compliance of the machine and the entire device by customer because EMC changes configuration of the control panel, wiring, and layout. -
Page 20: Restrictions
5-3-4. Restrictions The I / O cable must be under 30m from the host controller to the converter. The wiring should be surely secured. [Reference] It may be improved when clamp ferrite core is added to the power supply cable, sensor cable, and I/O cable when it operates faultily by the influence from the peripheral device. -

6. WIRING 6-1. Connection between Converter and ABSOCODER Sensor The maximum extension sensor cable length varies according to the ABSOCODER sensor and cable model being used. Please refer to the 3-2 for details. ● Wiring Precautions The sensor cable should be clamped as shown in the right figure to prevent excessive tension from being applied to the cable connectors. -

Page 30: Position Data Reading Setting
8-4. Position Data Reading Setting 8-4-1. Position Data Reading by LP output Position data reading is synchronized with the LP output signal from the converter. Either high-speed or low-speed reading can be selected. (1) High-speed reading When high-speed reading is selected, the position data output is updated at the leading edge of the LP output signal. - Page 31 (2) Low-speed reading (at LP=LOW) When low-speed reading (at LP =LOW) is selected, the position data output is updated when the LP output signal is HIGH. It stabilizes when the LP output signal is LOW, so the position data should be read at that time.

Page 32: Position Data Reading By Hold (Hd) Input
8-4-2. Position Data Reading by HOLD (HD) Input The HOLD input signal is used to HOLD position data outputs from the host controller. Either of the following two position data HOLD formats can be selected. (1) Transparent format Position data output updating is stopped by an HOLD input signal from the host controller (PLC, etc.). The position data should be read at that time. - Page 33 (2) PC synchro format Position data output updating occurs when the HOLD input signal status changes (leading edge or trailing edge), and is not synchronized with the LP output signal. Position data reading should be performed after waiting period "t3" following the HOLD input signal status is changed by the host controller (PLC, etc.).
-
Page 34: Position Data Output Format Setting
8-5. Position Data Output Format Setting This setting applies for the NCV-30NBNLC only. Select the position data output format from the binary code, sign magnitude code, or minus zone “0” output. Binary code output: Outputs 24-bit of binary code. Sing magnitude code output: D23 output changes to minus sign output. The minus sign output is ON when the machine position travels to the minus side. -
Page 35: System Ready Signal
8-6. System Ready Signal The system ready signal indicates that the normal position data is output from the converter. The signal is “LOW level” when ABSOCODER sensor and converter operate normally. For your safety, read the position data when the system ready signal is “LOW level”. The system ready signal is “HIGH level”... -
