5.1 Switch-on sequence
•
Switch on Mains voltage and Mains contactor
•
first time assign parameters to suit the respective conditions.
•
Specify controller enable and set point
Caution!
On the control plugs X4 and X5, first must the voltage switched on, after the
equipment is switched on, that means after the main voltage and contactors become
switched on and the equipment reports „ready“.
5.2 Display
The 7-segment display displays the instantaneous status of the unit. (The status of the unit
can also be ascertained using the “UniDesk“ operating software).
Display off: control voltage has failed or is too low. Unit is non-
operational.
0- not ready: no fault , but mains voltage is not enough present. In this
condition, the inverter waits for the built up of the main voltage.
1- Ready: no fault. The drive can be started immediately.
2- Clockwise rotation: no fault. The inverter generates a clockwise ro-
tating field
3- Anti-clockwise rotation: no fault . The inverter generates an anti-
clockwise rotating field.
F1- Undervoltage mains: the intermediate circuit voltage has dropped
below a critical value. (This fault is triggered only during controller en-
able) Drive switched off.
Check power supply. (3.1)
F2- Overvoltage : the intermediate circuit voltage has exceeded a criti-
cal value. Drive switched off.
Check power supply, check motor braking energy. (3.1)
