Actual value display via codes

You can read different actual values using the following codes:
Code Meaning
C0051 Absolute actual speed [rpm]
C0052 Absolute motor voltage [V]
C0053 Absolute DC bus voltage [V]
C0054 Absolute motor current [A]
C0060 Rotor position [Inc/rev]
C0061 Heatsink temperature [°C]
C0063 Absolute motor temperature [°C]
Display only if the KTY (PTC) is connected via X7 or X8.
C0064 Controller load [%]
Identification
•
You can read the software version of the controller under C0099.
•
C0093 indicates the controller type.

Information on operation

When operating the controller, please observe the following notes:
Stop!
•
Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or +U
-U may overload the internal input current limitation:
G
– Allow at least 3 minutes between disconnection and reconnection.
•
During mains switching (L1,L2,L3) it is not important whether further controllers are supplied
via the DC bus.

Switching on the motor side

•
Switching on the motor side of the inverter is permissible for emergency switch-off.
•
Please note:
– Switching while a controller is enabled may cause the fault message "OCx"
(short-circuit/earth fault in operating mode x).
– For long motor cables and operation of controllers with smaller output power, leakage
currents through interfering cable capacitances may cause the fault message "OCx".
– Switching equipment on the motor side must be dimensioned for DC voltages
(U = 800 V).
