SSU - 6 Velocity Drive Setup Ver. 0002

The figure shows a possible look of the oscilloscope screen and its interpretation depending

on the gains set.

During the setup process, it is common practice to monitor the velocity command

(SV1 -S00036-) and the actual speed (SV2 -S00040-).

CALCULATION OF VALUES

Speed = 100 rpm/10volts * 2 volt/division * 3 divisions = 60 rpm

Torque= 1 dNm/10volts * 5 volt/division * 2 divisions = 1 dNm = 0.1Nm

Warning:

Give to OP3 -F01403- and OP4 -F01404 values that cannot be reached by the chosen

internal variables. This way, the output will never exceed the ±10V range.

For example, if the speed is not expected to ever exceed 2500 rpm, the gain may be

set in 2500 rpm/10 volts or greater.

If the values given to OP3 -F01403- and OP4 -F01404 are too small, the electrical signal

will be saturated when reaching ±10 V.

The WinDDSSetup program for setting the drive up from a PC includes an oscilloscope.

This way, the setup is much easier.
