5.3.5 Drive tuning
5.3.5.1 Self tuning of the current regulator
The following operation must be done before enabling the drive for the first time.
The autotuning of the current regulator is enabled via the
R&L Search
command. The values stated for the ar
-
mature resistence and inductance are recorded as
Arm resistance
and
Arm inductance (
CURRENT REGULAT
menu). If necessary the user can change these parameters value.
- If the motor field is externally power supplied (not from the drive), disconnect the motor field supply terminals.
It is not necessary when the motor field power supply comes from the drive (C1 & D1 terminals)
- The user must be sure that during the current regulator self tuning the motor shaft does not turn (remanent
magnetization, field series motor, etc.). If necessary, lock the motor shaft during the procedure.
- AC input voltage to U2 and V2 terminals,
- Drive disabled ( no +24 voltage at terminal 12 )
- Set
Main commands
parameter (START UP or CONFIGURATION menu) to “Digital” (Enable & Start/
stop command from the keypad).
- Set the Armature current desired via
T current lim +
(positive torque) and
T curent lim -
(Negative torque).
- Set Overload control function to disable. (
Enable overload
= Disabled).
- Set
R&L Search
command to ON (START UP menu)
- Power up the drive
- Power up U, V, W terminals
- Enable the drive (+24V to terminal 12) and Start (+24V to terminal 13 and 14).
-
Enable drive
command = ENABLE (START UP menu).

If
Stop mode
parameter is not set to “OFF” (FUNCTIONS/Stop Control menu), press Start
button on the keypad.
- The
R&L Search
takes a few minutes, and can be interrupted by powering off the drive or set
Enable drive
to disable.
- At the end of the current self tuning procedure the drive is automatically set to disabled and the
R&L
Search
command to OFF.
- Set the
Enable drive
parameter to disabled (No voltage on terminal 12)
- Set
Main commands
parameter to the desired setting (Terminals or Digital).
- Set Overload control function to enable if used. (
Enable overload
= Enabled).
- Save setting via
Save parameters
command (START UP menu)

The procedure can be interrupted by powering off the drive or set
Enable drive
to disable.
The previous parameters setting are stored in the drive. It is not possible to start the procedure
if the Enable drive is set to disable.
5.3.5.1.1 Checking current regulator performance using parameter Eint
While running the drive, monitor the parameter (
Eint
), located under menu heading “Current Regulator”. This
measure an average internal current error.
Its value should be close to zero, but values dynamically changing between -40 and 40 are acceptable.
The drive
must have at least 30% load for this reading to be considered as a valid performance measurement.
If
adjustments are needed, make small changes to the parameter (Current regulator\Arm inductance) to fine tune
(
Eint
) to an acceptable value.
- If
Eint
is positive value, increase “Arm inductance” value.
- If
Eint
is negative value, decrease “Arm inductance” value.
