Enable the input programmed as Slave. The Slave function allows to bypass the speed loop and to turn the main
reference into a torque reference.

The inverter manages the signal sent from a thermistor incorporated in the motor windings to obtain a hardware
thermal protection of the motor. The thermistor ratings must comply with BS4999 Pt.111 (DIN44081/DIN44082):
Resistor corresponding to trip value: 1000 ohm (typical rating)
Resistor at Tr–5°C:
< 550 ohm
Resistor at Tr+5°C:
> 1330 ohm
Do the following to use the thermistor:
1) Set jumper J9 to position 1–2,
2) Connect thermistor between terminals 13 and 14 in the control board,
3) Set MDI5 as auxiliary trip.
In that way, the inverter will stop and indicate an auxiliary trip (“external alarm”) as soon as the motor temperature
exceeds threshold value Tr.

Enable the input programmed as Loc/Rem. This function allows to override parameters C21/C22 (IFD SW) or
C14/C16 (VTC SW) and to use them in local mode (Keypad). If the input is disabled, prior setup is reset.

C23=C24=C27= Fire Mode
When inputs set as Fire Mode are enabled, any protection feature of the inverter is ignored, so that no alarm trips (see
section 3.5 ”FIRE MODE FUNCTION“ for more details).
CAUTION
If an asterisk (*) appears next to INVERTER OK on the display, the product guarantee is
no longer valid.
The asterisk appears if at least one condition requiring the activation of a protection
feature occurs when the inverter is running in Fire Mode.
