3.2.2 ControlBox, SK TU3-CTR
This option is used as a simple parameterisation, display and control tool
for the frequency inverter SK 5xxE.
Features
•
4-digit, 7-segment LED display
•
Direct control of a frequency inverter
•
Display of the active parameter set and operating values
•
Storage of a complete inverter data set (P550),
e.g. for transfer of data to other frequency inverters.
After the ControlBox has been attached, the cable connectors plugged in
and the mains has been switched on, horizontal lines appear in the 4-digit 7-segment display. This display
signals the operational readiness of the frequency inverter.
If a creep frequency value is pre-set in parameter P113, or a minimum frequency is pre-set in P104, the
display flashes with this initial value.
If the frequency inverter is enabled, the display changes automatically to the operating value selected in
parameter >Selection Display value< P001 (factory setting = current frequency).
The actual parameter set in use is shown by the 2 LEDs next to the display on the left in binary code.
NOTE
The digital frequency setpoint is factory set to 0Hz. To check whether the motor is working, a
frequency setpoint must be entered with the
key or a jog frequency via the respective
parameter >Jog frequency< (P113).
Settings should only be implemented by qualified personnel, strictly in accordance with the
warning and safety information.
ATTENTION :
The motor may start immediately after pressing the START key
