Function S-INT: Inverter behaviour at the current threshold
TAB1
This parameter defines the inverter behaviour when the output current exceeds the pro-
grammed threshold:
0:Internal handling disabled.
1:The inverter is immediatly stopped.
The display shows a blinking "ILIMIT".
2:The inverter is stopped after a programmable delay (see TAB1, SUB IMOT,
function DY).
The display shows a blinking "ILIMIT".
3:The acceleration ramp is halted and will be continued after the output current
drops below the current threshold.
The display shows a blinking "RAMP".
4:The motor will decelerate until the output current drops below the current
threshold by the value of HYS (see TAB1, SUB IMOT, function HYS).
The display shows a blinking "HYST".
SUB IMOT
Range: 0...4
Default: 0
Function DY: Delay time at the current threshold handling
TAB1
The inverter will wait for the time programmed with this parameter before indicating the
exceeding of the output current and/or stopping (see TAB1, SUB IMOT,
function S-INT and TAB3, function OC1, OC2, REL).
SUB IMOT
Range: 0...20 sec.
Default: 5 sec.
Function HYS: Current threshold hysteresis
TAB1
Output current hysteresis in % of the rated inverter output current.
When S-INT = 4 and the output current exceeds the threshold (see TAB1, SUB IMOT,
function S), the motor will decelerate, until the output current will drop below the cur-
rent threshold by the value of HYS.
SUB IMOT
Range: 2...30%
Default: 3%
S-INT 0
DY 5.0s
HYS 3%
