Function SW5: Error signalling relay configuration
TAB3
This function defines when the fault relay (terminal 122, 123, 124) becomes active.
ON: Fault relais becomes active on fault or when the inverter is disabled.
OFF:Fault relais becomes active only on fault.
SUB XPAR
Range: ON, OFF
Default: ON
Function SW6: DC - Brake trigger
TAB3
ON: The DC-brake is activated automatically if the output frequency sinks
below the frequency threshold 1 (TAB1, function U) and the setpoint input
value is zero or manually by activating terminal 30.
OFF:The DC-brake is ON if terminal is activated.
Indication: For the RESET to the DC-brake see configuration in TAB3,
SUBXPAR, function SW1.
SUB XPAR
Range: ON, OFF
Default: OFF
Function SW7: Autostart
TAB3
This function defines the start condition for line start (POWER-ON).
ON: With this setting, the inverter will turn on when the line power is applied and
the ENABLE and START/STOP-command is present.
OFF:Line start lockout. The inverter will not start upon application of the line
power. START/STOP or ENABLE must be opened, then closed to
start the drive.
SUB XPAR
Range: ON, OFF
Default: ON
Function SW8: "S" ramp
TAB3
S-form acceleration and deceleration ramps are selected with this function.
The ramp characteristic is calculated on the basis of the highest frequency value ente-
red in Fmax (TAB1, function 3), or FFIX1–FFIX3 (TAB1, SUB FFIX) and is symmetri-
cal with respect to the point of inflection. The point of inflection is located at the
frequency corresponding to half of the applied setpoint.
Fnx = Highest value from Fmax, FFIX1–FFIX3.
SUB XPAR
Range: ON, OFF
Default: OFF
SW5 ON
SW6 OFF
SW7 ON
SW8 OFF
