Command a speed and see what it actually is, for example command S1000 and see if the motor does 2000 or 1500 or whatever.
If you have software for the drive you should be able to hook up a computer so that you can see what the motor is doing.

I solved the problem. Was set up electronic gear.
The parameters were:
P46=10000
P4B=250
In this case the reduction is 40!

Another question. How can I connect  4 servo apmlifiers so if one EMERGENCY stop others stopped too?

It will all depend on the options you have with your drives. For example if there are both fault outputs and fault inputs then you can have them all wired so that if one drive faults it sends a signal to all of the drives fault input.

How it should look like in the diagram?

Not sure if Servo On is just an Enable, but you may be able to use that in conjunction with the Alarm signal. You may also be able to use the Inhibits but that will depend on how they work.
Afraid I have never had Panasonic drives so cant say exactly how they work with regards these signals.
