8.8.2.4
Assignment of the relay outputs
• Terminal -X2:41, 42:
You can control the main contactor using these terminals. The main contactor function is
not activated in the software for the NAMUR application. More detailed information is
provided in Chapter "Protective functions (Page 105)".
• Terminal -X2:37, 39:
All warnings which are acquired in board CB08 are signaled here with a changeover
contact in the open-circuit principle, e.g. message !! Prewarning !! Inverter overtemp.
• Terminal -X2:30, 31:
The "Rdy.f.work" message as normally open contact is available here. "Rdy.f.work" means
that the converter has no faults and the DC link is pre-charged.
• Terminal -X2:32, 33:
The contact closes if the motor is turning.
• Terminal -X2:34 ... 36:
"Converter fault" All faults which cause the converter to shut down are signaled here with
a changeover contact in the closed-circuit principle.
• Terminal -X2:43 ... 49:
In the case of the "peripheral board 4" option: then messages PTC X3:90, X2:9 and Speed
zero are active here.
8.8.2.5
Assignment of the analog inputs
• Terminal: -X2:50 ... 52:
– Apply the speed setpoint which is active in normal operation to these terminals.
– You can use the terminal 50 as current input or the terminal 52 as voltage input. The
– The input range from 0 mA to 20 mA or from 0 V to 10 V is proportional to the output
• Terminal: -X2:53, 54:
– The signal for the speed actual value feedback can be supplied to this input. The values
– You can connect an analog motor tachometer to these terminals.
– More detailed information is provided in Chapter "DIL switches "S1" and "S2"
– You can use the signal in the software for limit value comparisons or as display.
