Function S-INT: Inverter behaviour at the current limit
TAB1
This parameter defines the inverter behaviour when the output current exceeds the pro-
grammed limit:
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,
func. 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 limit.
The display shows a blinking "RAMP".
4: The motor will decelerate until the output current drops below the current
limit by the value of HYS (see TAB1, SUB IMOT, func. HYS).
The display shows a blinking "HYST".
SUB IMOT
Range: 0...4
Default: 0
Function DY: Delay time at the current limit 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,
func. S-INT and TAB3, func. OC1,OC2,REL).
SUB IMOT
Range: 0...20 sec.
Default: 5 sec.
Function HYS: Current limit hysteresis
TAB1
Output current hysteresis in % of the rated inverter output current.
When S-INT = 4 and the output current exceeds the limit (see TAB1, SUB IMOT, func.
S), the motor will decelerate, until the output current will drop below the current limit by
the value of HYS.
SUB IMOT
Range: 2...30%
Default: 3%
S-INT 0
DY 5.0s
HYS 3%
