8.8.1.7 Assignment of the digital inputs
Terminal -X2:13 External fault input. In the case of actuation with 24 V, this results in an error shut-
down with storage.
Terminal -X2:29 External warning. In the case of actuation with 24 V, this results in a warning without
storage.
Terminal -X2:27 Connect a motor PTC thermistor for the motor monitoring here. If the sensor is trig-
gered, a "Motor overtemperature " shutdown is performed, which is stored. More
detailed information can be found in the section "Multiple function of the analog and
digital inputs" (Page 160). In the case of the "peripheral board 2 / 4" option, connect
the PTC thermistor connector to the peripheral board.
Terminal -X2:28 Connect another motor PTC thermistor for the motor monitoring here. If the sensor
triggers, a warning with "!! Advance warning !! Motor overtemperature" is output,
which is not stored. More detailed information can be found in the section "Multiple
function of the analog and digital inputs" (Page 160). In the case of the "peripheral
board 2 / 4" option, connect the PTC thermistor connector to the peripheral board.
In the case of the "peripheral board
3 / 4" option
The digital inputs are set to inactive and can thus be freely used for other configura-
tions.
8.8.1.8 Assignment of the digital outputs
Relay 1, terminal -X2:37, 38, 39 The "Ready" message as changeover contact in the open-circuit principle is available
to you here. Ready for operation means that the inverter has no faults and the DC
link is preloaded.
Relay 2, terminal -X2:41, 42 The message "Working" is output here.
Relay 3, terminal -X2:30, 31 All warnings which are generated in board CB08 are signaled here in the open-circuit
principle. Example: The message "!! Prewarning !! Inverter overtemp."
Relay 4, terminal -X2:32, 33 -
Relay outputs, terminal
-X2:34, 35, 36
Inverter fault All faults which cause the inverter to shut down are signaled here with a
changeover contact in the closed-circuit principle.
In the case of the "peripheral board
3 / 4" option, terminals
-X2:43 … 49
The messages "Temp.Motor", "Shutdown", "Automat.operation" and "Speed zero"
are available.
8.8.1.9 Assignment of the analog inputs
● Analog input one, terminal -X2:50, 51, 52:
–
You apply your speed setpoint to these terminals which is effective in the "Remote"
mode.
– You can use the terminal 50 as current input or the terminal 52 as voltage input. The
terminal 51 is the ground connection.
– The input range from 0 mA to 20 mA or from 0 V to 10 V is proportional to the output
frequency from 0 Hz to 50 Hz.
● Analog input two, terminal -X2:53 and -X2:54:
–
Equivalent, additional analog input.
