Selection of the drive command (via terminals or digital)
- When the converter is controlled only via the terminal strip, set the Main commands parameter to “Ter-
minals”. Before change this parameter set be sure that no voltage is supplied to terminal 12.
- When the keypad is used Main commands = Digital
Saving Settings
- Use Save parameters in SPECIAL FUNCTION menu
- User parameters setting must be saved into memory, so that the stored values are read the next time the
device is switched on.
- When using the keypad: press ENT.
On standard setting, to perform the self tuning of cuurent regulator during the commissioning, the Main com-
mands parameter is set as “Digital”.
5.3.4 START up procedures
Following START UP menu allows a quick basic commissioning of the drive.
Speed base value This value determines the max rpm corresponding to the max signal applied to an analog
input (e.g. 10V or 20mA).
Nom flux curr Nominal field current of the drive. Set the range through the dip switches on the regula-
tion board. See table 2.4.3.2.
Speed-0 f weak Enables Speed-0 f weak at zero speed.
Speed-0 f weak delay Sets a time delay.
Acc delta …
Acceleration ramp time setting on the speed reference.
Dec delta ... Deceleration ramp time setting on the speed reference.
Motor data
In this menu all the motor plate data are placed.

! Performing the speed regulator self tuning the following parameters must be set correctly
according to the motor used.
Motor nom flux Motor nom flux in Amps.
Flux reg mode Flux regulator mode: constant current (fixed field) or Voltage control.
Full load curr Nominal armature current in Amps. It corresponds to the 100% of the nominal drive output
current. The default value is the nominal drive current. The settings for the current limits (T
current limit parameters) and the “Overload function” are based on this value.
Motor max speed Maximum motor speed value. Set the motor plate data value.
Max out voltage Maximum armature voltage value. When Flux reg mode is set to fld weakening, it cor-
responds to the crossover point.
Flux weak speed Motor max speed percentage where the flux weakening range starts. (Crossover
point)

! With speed regulator self tuning performed, the above parameters value can be changed.
