  • Page 25: Ce Marking

    5-3. CE Marking NCV-30H 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 26: 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.

  • Page 38: 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 39 (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 40: 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 41 (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 42: Position Data Output Format Setting

    8-5. Position Data Output Format Setting 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.
