Chapter 6 Parameter Description
91
When the output frequency less than FDT2 level lower limit, the signal is disabled. Refer to P7.22 ~
P7.23 for details.
4: Pre-warning signal indicating inverter overload or motor overload (OL)
When the output current is higher than the overload pre-warning detection level and the retention time is
higher than the overload pre-warning detection time, the signal is enabled. When the current is lower
than the detection level, the signal is disabled. Refer to PA13 ~ PA.15 for details.
5: Stop and lock due to under voltage (LU)
When the inverter bus voltage is lower than the under voltage action value, the signal is enabled.
6: Stop due to external failure(EXT)
When the inverter is in the protection status due to failure of peripherals (“E.oUt” appears on the
operation panel), the signal is enabled.
7: Frequency upper limit (FHL)
When the output frequency of the inverter reaches setup frequency upper limit, the signal is enabled.
8: Frequency lower limit (FLL)
When the output frequency of the inverter reaches setup frequency lower limit, the signal is enabled.
9: Inverter is running at zero speed.
When the output frequency of the inverter is 0, the single is enable.
10: Preset counting value action
11: Counting value arrival action
When the counting value of inverter input terminal complies with action, the signal is enabled, Refer to
P5.12 and P5.13 for details.
13: Inverter ready for operation (RDY)
When the auto-test of the inverter is normal after power on and the inverter operation disable function is
invalid or disable, the signal is enabled.
14: Inverter fault
When the inverter is in the stop status due to failure, the signal is enabled.
15: Inverter reports alarm
When the inverter is in the alarm status due to fault but does not stop, the signal is enabled.
19: Output X1
When the status of multifunctional input X1 terminal is output via the terminal Y, when X1 is enabled, the
signal is enabled.
20: Output X2
When the status of multifunctional input X2 terminal is output via the terminal Y, when X2 is enabled, the
signal is enabled.
22: Zero current detection arrival
When the output current of the inverter is lower than the zero current detection width during operation,
the signal is enabled. Refer to P7.18 for details.
23: Stop command instruction
When the inverter is in the stop or standby status, the signal is enabled.
12, 16, 17, 18, 21and 24 ~ 47: Reserved
