Up to 5 outputs (2 of which are relays) are available, which can be freely programmed with digital
functions. These can be seen in the following table.
[-01] = Output 1 / MFR1, relay output 1: External brake, (default), terminal 1/2
[-02] = Output 2 / MFR2, relay output 2: Error, (default), terminal 3/4

Outputs 1 and 2 (MFR1: Control terminals 1/2 and MFR2: Control terminals 3/4): The
settings 3 to 5 and 11 work with a 10% hysteresis, i.e. the relay contact closes (Function 11
opens) when the limit value is reached and opens (function 11 closes) when a 10% smaller value
is undershot. This behaviour can be inverted with a negative value in P435.

List of possible functions of the relays and digital outputs
Value Function Description Signal*
00 No function Input switched off. Low
01 External brake For the control of a mechanical brake on the motor. The relay switches at a
programmed absolute minimum frequency (P505). For typical brakes a setpoint
delay of 0.2 … 0.3 seconds should be programmed (see also P107).
A mechanical brake may be directly switched by AC current. (Note the technical
specification of the relay contacts!) High
02 Inverter working the closed relay contact indicates voltage at the inverter output (U - V - W) (also DC
run-
on(→ P559)).
High
03 Current limit Based on the setting of the motor rated current in P203. This value can be adjusted
with the standardisation (P435). High
04 Torque current limit Based on motor data settings in P203 and P206. Signals a corresponding torque
load on the motor. This value can be adjusted with the standardisation (P435). High
05 Frequency limit Based on motor nominal frequency setting in P201. This value can be adjusted with
the standardisation (P435). High
06 Setpoint reached indicates that the FI has completed the frequency increase or decrease. Setpoint
frequency = actual frequency! From a difference of 1 Hz
à Setpoint not reached -
contact opens.
High
07 Fault General fault message, fault is active or not yet acknowledged. à Error – contact
opens (ready – contact closes)
Low
08 Warning General warning - a limit value was reached that could lead to a later shutdown of
the FI. Low
09 Overcurrent warning At least 130% of the nominal FI current was supplied for 30 seconds. Low

Digital input 7 (DIN7) can also be used as digital output 3 (DOUT3 / Binary output 5). It is recommended that either an input function (P420 [-07]
or an output function (P434 [-05]) is parameterised. However, if and input function and an output function are parameterised, a High signal from
the output function will result in the activation of the input function. This IO-exclusion is hence used as a kind of "flag". This also applies for digital
input 8 (DIN8) and digital output 2 (DOUT2 / binary output 4).
