S120: set speed value in homing via starter software

hello,

i have a problem in the same sinamics drive type S120

As when electricity cut out, all machine parameters cleared to ### (somehow over range)

and i have to make homing from starter software. and there's one motor attached with mechanical chain, the chain broken every time i make homing as motor moves with its maximum speed to be in reference value

please your support to set speed value in homing via starter software instead of moving with maximum speed and also a method to overcome problem of over-range after electric cut out

Thanks

Split from please tell me how to ask question in foums.

Changing parameters online with STARTER or Startdrive are made in the RAM of the drive and will be lost when you switch of the power.

You have to do "RAM to ROM" in STARTER or "save parameters permanent" in Startdrive. 

Doing this the drive will keep the parameter changes even when the power is switched of.
