4.2 Mounted components
Figure 4-2 Locations of the mounted components on the drive
The following resistors and capacitors are mounted on socket SK1:
RIP resistor
Reduces the peak current to the required value.
RAI resistor
Compensates for the voltage drop due to internal resistance of the motor.
RIN resistor
Reduces the nominal current to the required value.
RKW.CRA resistor
Adjusts the drive for armature voltage speed feedback.
DER capacitor
Adjusts derivative gain.
INT capacitor
Adjusts integral gain.
JUMP.CRA jumper
Adjusts the response of the system when the drive is in armature feedback mode.
RT resistor
Normalizes the tachogenerator input signal and adapts the drive to the voltage
constant of the tachogenerator.
Most applications do not require DER or INT capacitors to be used. When an
application does require these capacitors, the recommended value is between 0.1mF
and 5mF.
