6ra80 SINAMICS DCM drive comissioning f60058

Dear Sir,

I am commissioning a Sinamics DCm 6ra80 for two axes, hoisting and traveling.

My configuration:

Traveling: I am using a 400 VDC motror with 165 Amps with no encoder (p50083=3) and No field(external field). I want to set Field weakening active (p50081 = 1)  but can not, occur f60058. Pls help me what parameters set to active field weakening?

Hello.

Field weakening active (p50081 = 1) is not permissible when the EMF is used as speed setpoint (p50083 = 3). You need tacho or encoder.

Thanks for your repply,

My config for Crane; A Drive for two exes: Hoisting (DDS0), Gantry(DDS1). 

Hoisting have a tacho but gantry not. So i can not field weakening active (p50081 = 1). 

With hoisting run more than 50% speed will occur F50043. Pls help me How to fix this fault to increase

speed to about 80% reference

Thanks/AutoVN
