APPENDICES 1. VE-2B(G) AND NCV-20 COMPATIBILITY
The NCV-20 has backward compatibility with the VE-2B(G), although its outer dimensions are different due to
its compact size.
Appendix 1-1. VE-2B(G) and NCV-20 Differences
Item Description VE-2B (G) NCV-20

If the mounting fixture option part
"NCV-K1" is applied, the mounting
hole of VE-2B can be used.
See VE-2B outline Dwg.

position data
gap
Change the current position data of
NCV-20 to the same value as VE-2B(G)
by using "current position setting function".
Please refer to the section "8-4. Current
position setting" for the setting process
of current position setting.
The origin position of NCV-20 is different from
VE-2B by an individual variability.
There are no differences other than those indicated above.
Appendix 1-2. Replacement Models
The VE-2B (G) models and their corresponding NCV-20 replacement models are shown below.

Appendix 1-3. Switch Settings when Replacing VE-2B (G) with NCV-20
Specify NCV-20 switch settings to obtain the same functions as the current VE-2B (G) which is being
replaced.
