Application Guide
MAINTENANCE HAZARD
Only an approved electrician can do maintenance. There is a risk of injury.
-
Do not do maintenance if you are not approved to do it.
The revolutions mode uses motor speed, which is only an estimate. The drive measures the speed every second.
When the value of a counter is more than its limit, an alarm, or a fault shows. It is possible connect the alarm and fault signals to a
digital output or a relay output.
When the maintenance is completed, reset the counter with a digital input or parameter P3.16.4 Counter 1 Reset.

tenance alarm occurs.

11.19 Fire Mode
11.19.1 The Fire Mode Function
When Fire mode is active, the drive resets all faults that occur and continues to operate at the same speed until it is not possible.
The drive ignores all commands from the keypad, fieldbuses, and the PC tool. It only obeys the signals Fire Mode Activation, Fire
Mode Reverse, Run Enable, Run Interlock 1, and Run Interlock 2 from I/O.
The Fire mode function has 2 modes, the Test mode, and the Enabled mode. To select a mode, write a password in parameter
P3.17.1 (Fire Mode Password). In the Test mode, the drive does not automatically reset the faults, and the drive stops when a fault
occurs.
It is also possible to configure Fire mode with the Fire mode wizard, which can be activated in the Quick Setup menu with parame-
ter B1.1.4.
When the Fire mode function is activated, an alarm shows on the display.
