1.2.3 Control wiring for a CU240S Control Unit with default setting
Basic control with the default settings
When shipped from the factory and fitted to the power module, a factory reset must be
performed to read the power stack data into the control unit, before operating the inverter
with the basic settings.
To operate the inverter with the basic settings, (without additional parameterization or DIP
switch setting) the following conditions have to be fullfilled:
• The rated current of the inverter is at least as great as the rated current of the motor.
• The power range of the inverter matches the power range of the motor.
• The controlled motor is a 4-pole motor (best Siemens 1LA7).
• The default motor frequency for the inverter is 50 Hz and the units of measure is kW.
Control settings
• Run and Stop Command
The run and stop commands can be given using digital input 0 on terminal 5.
• Frequency Setpoint
The required frequency can be achieved connecting a potentiometer to the analog inputs
on terminals 3 and 4.
• Reverse
A change of direction can be accomplished using digital input 1 on terminal 6.
• Fault Acknowledge (Ack)
A fault on the inverter can be acknowledged using digital input 2 on terminal 7. This
allows the fault signal to be reset.
• Output Frequency
The actual output frequency can be displayed using the analog outputs on terminals 12
and 13.
• Fault
Using relay 1 (RL1) on terminals 19 and 20 a fault condition can be indicated. For
example using a lamp which will light-up to indicate a fault condition has occurred.
• Warning
Using relay 2 (RL2) on terminals 21 and 22 a warning condition can be indicated. For
example using a lamp which will light-up to indicate a warning condition has occurred.
