This error may occur at activated brake control (see Chapter 6.9.6.) if the load is below
the minimum load level (Pn.58) during start up.
To indicate overshooting and unpermissble limits the speed measurement generates
the error message E.co1 / E.co2. This error occurs when in any section of the speed
or frequency calculation a speed > 9999 min
occurs.
Inverter status E.co1 = 54
Inverter status E.co2 = 55
Error of the control circuit ; switch off the inverter and wait as long until the display is
dark. Then switch on the inverter. If the error still occurs, the control circuit is damaged
and must be back to the factory.
