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 ).
