Page 25: Ce Marking
5-3. CE Marking NCV-20H 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. -

The direction in which the position data increases is specified by a switch on the converter's rear face. Switch setting Increase Switch setting Alteration of the position data direction... -
Page 35: Position Data Reading Setting
8-3. Position Data Reading Setting (1) Function setting switch list The following two position data reading formats are available: 1) Latch pulse (LP) format…Reads position data which is updated regularly in synchronization with a latch pulse output signal from the converter. 2) HOLD (HD) format…Reads position data while position data updates are stopped by a HOLD input signal. -
Page 36: Position Data Reading By Lp Output
(2) 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. ●High-speed reading When high-speed reading is selected, the position data output stabilizes at the trailing edge of the LP output signal. - Page 37 ●Low-speed reading (at LP=HIGH) When low-speed reading (at LP=HIGH) is selected, the position data output stabilizes when the LP output signal is HIGH. The position data should be read at that time. Position data update Switch setting cycle 12.8ms 12.8ms 3.2ms 6.4ms 25.6ms...

Page 38: Position Data Reading By Hold (Hd) Input
(3) Position data reading by HOLD (HD) input The HD input signal is used to HOLD position data outputs from the host controller. Either of the following 2 position data HOLD formats can be selected. ●Transparent format Position data output updating is stopped by an HD input signal from the host controller (PLC, etc.). The position data should be read at that time. -
Page 39: Current Position Setting
8-4. Current Position Setting The current position setting function changes the converter's position data output to a value that corresponds to the machine's current position. The position data can be changed to any desired value by using the rotary switch on the control panel. If an extension sensor cable is being used, the cable must be connected when performing the current position setting function. -
Page 40: For Gray Binary Code Output
(2) For gray binary code output <Current position setting procedure> 1) Secure the sensor to the machine, then move the machine to the desired position. 2) Obtain the position data that corresponds to the machine's current position. 3) Convert the position data obtained at step 2) above to gray binary code. 4) Use the control panel's rotary switches (in the D0 to D3 order) to specify monitor LED values that match the value converted at step 3) above. -
Page 41: Maintenance And Inspections
Check the signal. The wiring of the output signal has problems. Repair the wiring. If the troubleshooting procedures described above fail to solve the problem, the sensor or converter may be defective. In this case, please contact your NSD representative. -
