Protection parameter group 06
PARAMETER DESCRIPTION 110
5.7.4 Maintenance alarm function

Inverter counts operation time and trigger maintenance alarm output signal after time set.
Parameter Name Default Setting Range Content
06-17
P.261 Maintenance alarm
function

0
Off
1～9998 day
Used to set the time for maintenance alarm output signal
Maintenance alarm function

When the multi-function digital output terminal function selection (03-11 (P.85)) is equal to 18, it is the
maintenance alarm function. That is, when the number of operating days of the inverter reaches the setting value
of the maintenance alarm function 06-17 (P.261) value, the inverter multi-function relay will output a signal.
5.7.5 Short circuit protection

Use parameters to turn on the short-circuit detection protection function.
Parameter Name Default Setting Range Content
06-18
P.280

protection function
10
X0
Turn off short circuit to ground detect when inverter start
X1
Short circuit to ground detect when inverter start
0X
Turn off output short circuit,
1X
When output short circuit, built-in keypad shows SCP alarm
and inverter stops
Short circuit detection protection function

Parameter 06-18 (P.280) ones digits is used to set whether to detect the ground leakage current at motor start. If
the function is selected, and inverter detects output short-circuit current to ground, the inverter will stop output and
alarm “GF”.

Parameter 06-18 (P.280) tens digits is used to set whether to detect the output side short-circuit at motor start. If t
the function is selected, and inverter detects output side short-circuit, the inverter will stop output and alarm “SCP”.
Note: 1. 06-18 (P.280) short-circuit detection protection function is only implemented after the start signal is input in the
inverter.
