6.7 Current controller adjustment
When is a current controller adjustment required?
ƒ The motor data of the motor used is not contained in GDC (e.g. motors
from other manufacturers).
ƒ The application makes high demands on the dynamic performance of
the drive controller (e.g. dynamic positioning, cross cutter).
ƒ The motor/drive controller combination does conform to the standard
power−based assignment. The basic current controller settings only
match for a power−based assignment of the drive controller.
Measure Setting Explanation
Reduce maximum
current Reduce the value in
C0022 With the motor at standstill, the motor
current of the motor phase U is measured
(field frequency 0). This increases the
motor current in the motor phase to
141% and the motor temperature rises
significantly.
Generate maximum
torque setpoint Connect MCTRL−M−ADD
with FIXED100% For speed control or position control
(MCTRL−N/M−SWT = 0)
l Connect
MCTRL−M−ADD with
FIXED100%
l Connect
MCTRL−N−SET with
FIXED100%
For torque control (MCTRL−N/M−SWT = 1)
Deactivate integral
action component of
current controller Set C0076 = 2000 ms The integral action component of the
current controller is deactivated by
setting the reset time T
n
(C0076) to the
longest time. The gain (C0075) remains
unchanged (Lenze setting still valid).
Deactivate quick stop Set X5/E1 = HIGH or
X5/E2 = HIGH By preselecting a direction of rotation the
quick stop is deactivated.
Change the operation of
the motor control Set C0006 = 3 Even if an asynchronous motor is
connected, set the motor control to
’synchronous motor’.
Set the rotor position
setpoint Set C0058 = −90° Set the rotor displacement angle to −90°.
Set the actual value
display of the rotor
position to 0° under
C0060 1. Select a TTL encoder
under C0025
2. Save settings with
C0003 = 1
3. If required,
disconnect the
encoder cable at X8
4. Switch off the mains
supply and the
external 24V supply
(if required) and then
on again.
After mains connection C0060 = 0° is
displayed.
Connect the storage
oscilloscope Put the clamp−on
ammeter around the
motor phase U and
connect it to the
oscilloscope Oscilloscope settings:
