12: When the fault is predicted, the corresponding output point is connected, otherwise it will be
disconnected;
112: When the fault is predicted, the corresponding output point is disconnected, otherwise it will be
connected.
13 or 113: Spare
14 or 114: Zero servo torque direction judgment (used at motor power outage emergency
leveling, spare)
14: When the test load of the inverter is heavy and the counterweight is light, the corresponding
output point is connected, otherwise it will be disconnected;
114: When the test load of the inverter is heavy and the counterweight is light, the corresponding
output point is disconnected, otherwise it will be connected.
15 or 115: Zero current detection
15: When the inverter stops running, if the output current of the inverter is greater than the zero
current detection threshold (set by P31.20), the corresponding output point is connected, otherwise it
will be disconnected;
115: When the inverter stops running, if the output current of the inverter is greater than the zero
current detection threshold (set by P31.20), the corresponding output point is disconnected,
otherwise it will be connected;
16 or 116: Power generation and electric status discrimination
16: 0 - power-driven state; 1 - power generation;
116: 0 - power generation; 1 - power-driven state.
17 or 117: Output contactor closing
17: When the output value is 1, the contactor will be closed;
117: When the output value is 0, the contactor will be closed.
Usually, it is combined with input function 21 to control the output contactor to pull in before the
inverter outputs current.
21 or 121: Greater than 90 degrees, overheat alarm
Radiator temperature greater than or equal to 90, corresponding output point connected, otherwise it
is disconnected.
22: Motor overheat alarm output
23: Motor switching output
Motor selection output, corresponding output point disconnected: Motor 1, corresponding output
point connected: Motor 2.
24: Encoder switching output
Encoder selection output, corresponding output point disconnected: Encoder 1, corresponding output
point connected: Encoder 2.
25: Holding brake output
Holding brake opened, output point connected: holding brake closed loop, output point disconnected
26: Accumulated running time arrival
If the accumulated running time of inverter exceeds the time set by P31.25, the output terminal is
connected, otherwise it is disconnected.
27: Setting continuous running time arrival
If the accumulated running time of inverter exceeds the time set by P31.24, the output terminal is
