0 ... 38
[ 1 ] Functions for the signal relay 1 (Control terminals 1 / 2)
The settings 3 to 5 and 11 work with 10% hysteresis, i.e. the relay contact closes (fct. 11 opens) when
the limit value is reached and opens (function 11 closes) when a 10% smaller value is undershot.

0 = No function
open
1 = External brake
, to control a brake on the motor. The relay switches at a
programmed absolute minimum frequency (P505). A setpoint delay should be
programmed for typical brakes (see P107).
A mechanical brake can be directly AC switched. (Please note the technical
specifications of the relay contacts)
Closes
2 = Inverter is working
, the closed relay contact indicates voltage
FI output (U - V - W).
Closes
3 = Current limit,
based on the setting of the motor rated 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 on the motor. 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. After the contact has closed, the setpoint must change
by at least 1Hz
Æ
setpoint value not reached, contact opens
Closes
7 = Fault,
general error message, error is active or not yet acknowledged. Æ
Operational - closes
Opens
8 = Warning
; total warning, a limit value was reached that could lead to a later
shutdown of the FI.
Opens
9 = Overcurrent warning
, min. 130% FI nominal current for 30 sec.
Opens
10 = Motor overtemperature motor
: The motor temperature is evaluated via a
digital input. Æ Motor is too hot. Warning occurs after 1 seconds, overheating
switch off after 2 seconds.
Opens
11 = Torque current limit (warning)
, The limit value in P112 / P536 is reached. A
negative value in P435 inverts the reaction. Hysteresis = 10%.
Opens
12 = Value of P541
, using parameter P541 (Bit 0), the relay can be controlled
independently of the actual operating status of the FI.
Closes
13 = Torque current limit generally active with ISD control:
Limit value in P112
has been reached in the generator range. Hysteresis = 10%; Torque limit gen.
