Actual signals and parameters
216
95 HARDWARE SPECIF
Fan speed control, sine filter application etc.
95.01 FAN SPD CTRL
MODE Selects the speed control of the optional inverter cooling fan.
CONST 50 Hz Fan is running at constant frequency of 50 Hz when powered. 0
RUN/STOP Drive stopped: Fan is running at constant frequency of 10 Hz.
Drive running: Fan is running at constant frequency of 50 Hz. 1
CONTROLLED The speed of the fan is determined from IGBT temperature vs. fan speed
curve. 2
95.02 FUSE SWITCH CTRL Activates the inverter DC switch (switch fuse) monitoring function. The
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.
OFF Inactive 0
ON Active 1
95.03 INT CONFIG USER Number of parallel connected inverter modules. Activates the Reduced run
function. See section
Reduced run function on page 116 .
1...12 Number of parallel connected inverter modules
95.04 EX/SIN REQUEST Activates the sine filter or Ex-motor application.
NO Inactive 1
EX Ex-motor application. Used with motors which comply with the ATEX directive. 2
SIN Sine filter application. See Sine Filters User’s Manual for ACS800 Drives
[3AFE68389178 (English)].
3
EX&SIN EX-motor and sine filter applications. See Sine Filters User’s Manual for
ACS800 Drives [3AFE68389178 (English)].
4
95.05 ENA INC SW FREQ Activates the minimum switching frequency limitation for Ex-motor
applications. Parameter is visible if parameter
95.04 EX/SIN REQUEST is set
to EX.
NO Inactive 0
YES Active. Minimum switching frequency limit is set to 2 kHz. Used with motors
with an ATEX certification based on 2 kHz minimum switching frequency. 1
