Digital out function
[-01]
(Digital output function)
[-02]
0 ... 40
[-01] = Digital output 1, Digital output 1 of the variable frequency drive
{ 7 }
[-02] = Digital output 2, Digital output 2 of the variable frequency drive (only SK 2x0E)
Settings 3 to 5 and 11 operate with a 10% hysteresis, i.e. the output delivers (Funct. 11 does not
deliver) when the limit value 24 V is reached and switches this off again when a 10% lower value is
undershot (Funct. 11 on again).
This behavior can be inverted with a negative value in P435.
Setting/Function
0 =
No function
1 =
External brake, to control an external 24 V brake relay (max. 20 mA). The
output switches at a programmed absolute minimum frequency (P505).
For typical brakes a setpoint delay of 0.2-0.3 s should be programmed (see
also P107/P114).
SK 2x0E (Size 4) and SK 2x5E: A typical motor brake (105-180-205 V) can be
connected directly via control terminals 79 MB+/80 MB- (chapter 2.4.2.4).
2 =
Inverter is working, the output indicates voltage at the VFD output
3 =
Current limit, based on the setting of the nominal current (P203). This value
can be adjusted via scaling (P435).
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
via scaling (P435).
5 =
Frequency limit, based on nominal frequency setting in P201. This value can
be adjusted via scaling (P435).
6 =
Level with setpoint, indicates that the VFD has completed the frequency
increase or decrease. Setpoint frequency = actual frequency! From a
difference of 1 Hz
7 =
Fault, general fault message, error is active or not yet acknowledged.
- low (ready - high)
8 =
Warning, general warning, a limit was reached that could lead to a later
shutdown of the VFD.
9 =
Overcurrent warning: At least 130% of the VFD nominal current was
supplied for 30 seconds.
Mot. overtemp. warning, "Motor overtemperature warning": The motor
10 =
temperature is evaluated. Motor is too hot. The warning is given
immediately, overheating switch-off after 2 seconds.
Torque current limit, "Torque current limit/current limit active warning": The
11 =
limiting value in P112 or P536 has been reached. A negative value in P435
inverts the reaction. Hysteresis = 10%.
Value of P541, "Value of P541 - external control, the output can be controlled
12 =
with parameter P541 (Bit 0) independent of the actual operating status of the
VFD.
Torq.curr. limit gen, "Drive torque current limit active": Limit value in P112
13 =
has been reached in the generator range. Hysteresis = 10%
16 =
Comparison val. AIN1,
SK 2x0E:
Setpoint AIN1 of the VFD is compared with the value in (P435[-01 or -02]).
SK 2x5E: Setpoint AIN1 of 1st I/O extension is compared with value in
(P435[-01])
BU 0200 en-US-4920
Setpoint value not achieved – signal low.
