DETAILED PARAMETER DESCRIPTION
Notes:
‘Not Used’ it means that the digital outputs will remain always in a resting state, i.e., DOx = open transistor
and/or RLx = relay with the coil not energized.
‘N = 0’ it means that the motor speed is below the value adjusted in P0291 (Zero Speed Zone).
‘Remote’ it means that the inverter is operating in Remote situation.
‘Run’ it corresponds to enabled inverter. In this state, the IGBTs are commutating, and the motor may be
at any speed, even zero speed.
‘Ready’ it corresponds to the inverter without error and without undervoltage.
‘No Fault’ it means that the inverter is not disabled by any type of fault.
‘No F0070+F0071’ it means that the inverter is not disabled by faults F0070 or F0071.
‘No F0072’ it means that the inverter is not disabled by faults F0072.
‘4 to 20 mA Reference OK’ it means that the reference in current is within the 4 to 20 mA range.
‘Forward’ it means that when the motor is rotating in the forward direction, the DOx = saturated tran-
sistor and/or RLx = relay with the coil energized. When the motor is rotating in the reverse direction, the
DOx = open transistor and/or RLx = relay with the coil not energized.
‘Pre-charge OK’ it means that the DC Link voltage is above the pre-charge voltage level.
‘Fault’ it means that the inverter is disabled by a fault.
‘N > Nx and Nt > Nx’ it means that both the conditions must be satisfied, so that DOx = saturated tran-
sistor and/or RLx = relay with the coil energized. In order that the digital outputs go back to the resting
state, i.e., DOx = open transistor and/or RLx = relay with the coil not energized, it is necessary that only
the condition N > Nx not be satisfied anymore (regardless of the Nt > Nx condition).
Definition of the symbols used with the functions:
N* = P0001 (Motor speed reference);
N = P0002 (Motor speed);
Nx = P0288 (Nx Speed) - It is a reference point of the speed selected by the user.
Ny = P0289 (Ny Speed) - It is a reference point of the speed selected by the user.
Ix = P0290 (Ix Current) - It is a reference point of the current selected by the user.
Is = P0003 (Motor Current);
Torque = P0009 (Motor Torque);
VPx = P0533 (Process variable X value) - It is a reference point of the process variable selected by the user.
VPy = P0534 (Process variable Y value) - It is a reference point of the process variable selected by the user.
Nt = Total Reference (refer to Figure 5.24 on page 5-40).
