Description
Fan speed control, sine filter application etc.
Selects the speed control of the optional inverter cooling fan.
Fan is running at constant frequency of 50 Hz when powered.
Drive stopped: Fan is running at constant frequency of 10 Hz.
Drive running: Fan is running at constant frequency of 50 Hz.
The speed of the fan is determined from IGBT temperature vs. fan speed
curve.
monitoring must be active when the Switch Fuse Control Board (ASFC) is in
use and connected to the inverter AINT board, that is in all frame R8i inverters
equipped with the DC switch. The function must be inactive in units that do not
use the ASFC board with the DC switch, that is for frame R2i...R7i inverters
and all single drive units where no DC switch exists. The default setting (ON or
OFF) for each unit is set accordingly at the factory as default.
ACS800 IGBT pulses are always blocked when the program detects that the
DC switch is opened or inverter charging is ongoing (at power switch on). The
application program generates alarm INV DISABLED if the DC switch is
opened when the inverter is stopped. The inverter trips to fault INV DISABLED
if the DC switch is opened when the inverter is running.
Inactive
Active
Number of parallel connected inverter modules. Activates the Reduced run
function. See section Reduced run function
Number of parallel connected inverter modules
Activates the sine filter or Ex-motor application.
Inactive
Ex-motor application. Used with motors which comply with the ATEX directive. 2
Sine filter application. See Sine Filters User's Manual for ACS800 Drives
[3AFE68389178 (English)].
EX-motor and sine filter applications. See Sine Filters User's Manual for
ACS800 Drives [3AFE68389178 (English)].
Activates the minimum switching frequency limitation for Ex-motor
applications. Parameter is visible if parameter
to EX.
Inactive
Active. Minimum switching frequency limit is set to 2 kHz. Used with motors
with an ATEX certification based on 2 kHz minimum switching frequency.
