ACA 635 IGBT Supply Sections
A-11
Control Panel
The Control Panel (CDP 312) is connected to 6-pin modular connector
X3 on the NAMC-21/22 board. The modular connectors on the NIOC
board are
not
intended for the Control Panel.
RS-485 Termination
Settings
When the Control Panel CDP 312 is connected to one NAMC-21/22
board only, the RS-485 line must be terminated on the NAMC-21/22
board by jumpers X5 as follows:
If the CDP 312 is connected to several NAMC 21/22 boards (RS-485
panel bus), the first and the last NAMC 21/22 board must be
terminated and the intermediate boards not terminated.
NLMD-01 Monitoring
Display
The NLMD-01 monitoring display is connected to 6-pin modular
connector X4 on the NAMC-21/22 board. The modular connectors on
the NIOC board are
not
intended for the monitoring display.
NIOC Board
Specifications
This table gives data for the external control connection board NIOC-
01 of the IGBT supply section. For external control connections of the
control section refer to Common Drive Control Manuals.
