The user defines the full load current of the motor via the Full load curr (FLC) parameter in the CONFIGURA-
TION menu. This is at the same time the output current of the inverter when T current ref = 10%.
T current ref Total current reference as a percentage of Full load curr. For this parameter the
6KDV3 ... Q4... converters need a positive value. In this case the negative references
are processed and correspond to a zero reference.
Mot cur threshld When the motor current exceeds the Full Load Current percentage threshold, this condi-
tion is signalled via a digital output.
Mot cur th delay The Mot cur th delay parameter can be used to set the delay after which the current
within limit condition is signalled..
Arm resistance Motor armature resistance in W. When self-tuning cycle is performed via R&L Search
this parameter is set to the obtained value. Therefore, if necessary, it can be changed.
Arm inductance Motor armature inductance in mH. When self-tuning cycle is performed via R&L Search
this parameter is set to the obtained value. Therefore, if necessary, it can be changed.
E int Auxiliary signal used to determine wheter the current regulator is correctly tuned. Its
value should be close to zero, but values dynamically changing between -40 and 40 are
accettable.
The drive must have at least 30% load for this reading to be considered as a valid per-
formance measurement (see chapter 5.3.5.1.1 for more detail setting) .
R&L Search Execution of self-tuning for the current regulator. The identified values for resistance and
inductance armature are set to the Arm resistance and Arm inductance parameters.
Zero torque The parameter can be used to set the reference value for the armature current T cur-
rent ref to zero so that the drive has no more torque.
Not active (H) T current ref not set to zero
Active (L) T current ref set to zero. The drive has no torque.
