Name Description
RLA Relay output
RLB Function see parameter CP.22
RLC ( factory setting: fault indication)
I1 X1.4 + X1.5 = fixed frequency 3
I2 no input = analog set value
0V Potential for digital in-/outputs
CRF Supply voltage for set value potentiometer (max. 4mA)
REF 0...10VDC for analog set value
COM Mass for analog in- and outputs
AOUT Analog output of real frequency 0...10VDC = 0...100Hz
+15V voltage supply for digital in-/outputs (max. 100mA)
R Preset rotation; forward has priority
F
ST/RST Power modules are triggered; if opening in case of error
Reset; if opening during operation, the motor costs.
In order to prevent a malfunction caused by interference voltage supply
on the control inputs, the following directions should be observed:
- Use shielded/drilled cables
- Lay shield on one side of the inverter onto earth potential
- Lay control and power cable separately (about 10...20 cm apart)
EMC
- Lay crossings in a right angle (in case it cannot be prevented)
