[7] Control terminals 1/2:
The settings 3 to 5 and 11 work with 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.

1 = External
brake , to control a brake on the motor. The relay switches at the
set absolute minimum frequency (P505, default: 2 Hz). A setpoint delay
should be programmed for typical brakes (see P107).
NOTE:
In the SK 300E, a DC voltage is generated for a brake and
supplied at the terminals -Br and +Br. The relay contact should generally
be used with a special brake voltage.

2 = Inverter
is working , the closed relay contact indicates voltage at the FI
output (U - V - W).
Closes
3 = Current
limit *, based on the setting of the motor nominal current in P203.
This value can be adjusted with the standardisation (P435).
Closes
4 = Torque current limit *, based on motor data settings in P203 and P206.
Signals a corresponding torque load. This value can be adjusted with the
standardisation (P435). Closes
5 = Frequency limit *, based on motor nominal frequency setting in P201.
This value can be adjusted with the standardisation (P435).
Closes
6 = Level
with Setpoint, indicates that the FI has completed the frequency
increase or decrease. Setpoint frequency = actual frequency! After the
contact is closed, the setpoint must change by at least 1 Hz.
Æ
Setpoint not reached - contact opens
Closes
7 = Fault, general Fault message. Fault is or not yet acknowledged.
Æ Operational - contact closes
Opens
8 = Warning: general warning, a limit value was reached that could lead to a
later shutdown of the FI.
Opens
9 = Overcurrent
warning : At least 130% FI nominal current was delivered for
30 sec. (l 2 t function)
Opens
10 = Overtemperature motor (warning): The motor temperature is evaluated
via a digital input. Æ Motor is too hot. Warning occurs after 1 second,
overheating switch off after 2 seconds. Opens
11 = Torque current limit/ current limit active (warning), limit value in P112
is reached. P435 has no significance. Hysteresis = 10%.
Opens
12 = Value of P541 - External control: The relay can be controlled using
parameter P541 (Bit 0), independently of the actual operating status of
the FI. Closes
