Pulse Encoder
Insulation (ACP600)
The tachometer shall be insulated electrically from stator or rotor to
prevent forming of current path through the tachometer. The usual
coupling-type encoder must have an electrically insulating coupling.
When a hollow-shaft type tachometer is used, the insulation can be
implemented by insulating the ball joints of the engaging arm, or
insulating the bar of the engaging arm. Shield of the tachometer cable
should be insulated from the tachometer frame. The other end of the
shield is grounded at the converter drive.
Installation of
Optional Modules and
Drive Window This section gives general installation instructions for Drive Window PC
tool and ACx 600 optional modules, such as fieldbus adapters, I/O
extension modules and the pulse encoder interface. Connection
examples are given at the end of the section.
Placement
The module should be installed on the DIN mounting rail inside the
cabinet. Follow the instructions given in the
Mechanical Installation
chapter of the module manual.
Power Supply
for the Module
The 24 V d.c. supply for one optional module is provided by the NIOC/
NIOCP board of the converter (NIOC: terminal X23, NIOCP: terminal
X4). The location of the NIOC/NIOCP board is shown in the
dimensional drawings (
Appendix B).
Fiber Optic Link Optional modules are connected via a DDCS fiber optic link to the
NAMC board or NDCO board (mounted on top of the NIOC board). The
terminals on the NAMC/NDCO board to which the cables are
connected are as follows:
* on NDCO board when NAMC-1 board is used
Observe color codes when installing fiber optic cables. Blue connectors
should go to blue terminals, and grey connectors to grey terminals.
In case multiple modules are installed on the same channel, they must
be connected in a ring.
