Pulse Encoder
Insulation (ACP 600)
The pulse encoder shall be insulated electrically from stator or rotor to
prevent forming of current path through the pulse encoder. The usual
coupling-type encoder must have an electrically insulating coupling.
When a hollow-shaft type pulse encoder 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 encoder cable
should be insulated from the encoder frame. See
Appendix B for
grounding of the other end of the encoder cable shield.

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 inside the unit on the location shown in
the dimensional drawings (
Appendix B ). Option modules for the frame
sizes R2 and R3 are installed outside the frequency converter. 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 (both mounted on top of the NIOC
board). The terminals on the NAMC/NDCO board to which the cables
are connected are given in the table below. Channel CH1 is on
NAMC-11 board. Channels CH0, CH2 and CH3 are on NDCO board.
NAMC-3 board includes channels CH0 to CH3.
* on NDCO board when NAMC-11 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.
