When 08-48=1, Fire Mode is enabled.
When fire mode is enabled, S6 will be defined to digital input of fire mode (03-0X=47).
When fire mode is enabled, inverter will become to fire mode. No matter inverter is running or
stopping, run and frequency command source will be covered by the setting of fire mode, keypad
display will show “ FIRE ”, some of protect functions will be ignored, please refer the table 4.3.35,
inverter will not stop.
When fire mode (03-0X=47) and outour overload (03-0X=68) function is triggered, the other
digital inputs will be ignored, the parameters just can be read by communication or keypad
display.
When 08-49=0, pelase disconnect the power first, remove external trigger signal and then
connect the power.
When 08-49=1, no need to disconnect the power, inverter will become to normal mode, run
and frequency will reture to original setting.
Note: Only Version V1.53 and above will meet the above functions.
Table 4.3.35 These functions will be ignoed when fire mode is triggered
0x2521H Fault Description
4 OH1 (Heat sink over heat)
5 OL1 (Motor overload)
6 OL2 (Inverter overload)
7 OT (Over torque)
25 FB (PID feedback signal error)
26 Keypad Removed
28 CE (Communication error)
46 OH4 (Motor over heat)
49 MtrSw (DI Motor Switch Fault)
58 PF(Protection error)
！Danger：
Fire mode:
The drive will run at full speed either in forward or reverse direction and ignore all software
protections until any one of the hardware protection is triggered or drive is damaged to achieve
the requirement of smoke extraction and reduce the hazard to humans.
Each bit of 08-50 presents an input:
08-50= 0 0 0 0 0 : Normal open
s6 1 : Normal close
Notes:
Please set 08-48=0 (fire mode disabled) before setting normal open or normal close contact.
Failure to comply may cause death or serious injury.
When 08-51=0, motor speed setting will follow 08-52. If the value of 08-52 is 100%, inverter
output frequency will follow the value of 01-02.
When 08-51=1, motor speed setting will follow PID control; when fire mode is enabled, PID
control will base on 10-47/10-48/10-49 (please refer the setting value of group 10)
When 08-51=2, frequency reference will become to 4-20mA (default setting of 04-00)
