KEB F5 INVERTER MAT NO. 07F5B3A-390A 1.8KVA 0.75KW MOTOR POWER. The inventory of the control circuit through an outside voltage source keeps the control in functional condition regardless. Of whether the power stage is turn off. To forestall unclear conditions at the outside power supply the essential system is to initially turn on the power supply and after that the inverter. A wrong system position or an encoder which is not securely mount may lead to dangerous conditions with gearless synchronous machines.
If the difference between set and actual speed cross over the speed level of this parameter the inverter will trip with “E.EF”. This parameter is mainly design for the period of load transfer and starting. To avoid failures caused by wrong system position or bad encoder mounting a combination with function ‚speed deviation‘ LF.46, LF.47, and LF.48 is recommended. The temporary proportional factor enables a better starting behavior at high static friction in the system. The duration is adjusted with LF.53 . A typical value here is 4000.
