Digital and Analog Inputs and Outputs
13-16 | CFW700
Some notes regarding the Digital and Relay Outputs are presented next.
„
Not Used: it means that the digital outputs will remain always in a resting state, i.e., DOx=open transistor and/
or relay with the coil not energized.
„
Zero Speed: it means that the motor speed is below the value adjusted in P0291 (Zero Speed).
„
Torque > Tx and Torque < Tx: they are valid only for P0202=5 or 4 (Vector Control). In those functions “Torque”
corresponds to the motor torque as indicated at parameter P0009.
„
Remote: it means that the inverter is operating in Remote situation.
„
Run: it corresponds to enabled inverter. In this moment the IGBTs are commutating, and the motor may be
at any speed, including zero.
„
Ready: it corresponds to the inverter without fault and without undervoltage.
„
No Fault: it means that the inverter is not disabled by any type of fault.
„
No F070: it means that the inverter is not disabled by the F070 fault (Overcurrent or Short-circuit).
„
No F071: it means that the inverter is not disabled by the F071 fault (Output Overcurrent).
„
No F006+F021+F022: it means that the inverter is not disabled by the F006 fault (Input Voltage Imbalance or
Phase Loss), neither by F021 (DC Link Undervoltage), nor by F022 (DC Link Overvoltage).
„
No F051: it means that the inverter is not disabled by the F051 fault (IGBT Overtemperature).
„
No F072: it means that the inverter is not disabled by the F072 fault (Motor Overload).
„
4 - 20 mA OK: it means that the current reference (4 to 20 mA) at the analog inputs AIx is inside the 4 to 20 mA
range.
„
P0695 Value: it means that the state of the digital output will be controlled by P0695, which is written via the
network. Refer to the CFW700 Serial communication manual for more details on this parameter.
„
Forward: it means that when the motor is rotating in the forward direction the DOx=saturated transistor and/or
relay with the coil energized, and when the motor is rotating in the reverse direction, the DOx=open transistor
and/or relay with the coil not energized.
„
Ride-Through: it means that the inverter is executing the Ride-Through function.
„
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 any type of fault.
„
N > Nx and Nt > Nx: (valid only for P0202=5 – Vector with Encoder) it means that both the conditions must
be satisfied so that DOx=saturated transistor and/or relay with the coil energized. In other words, it is enough
that the condition N>Nx be not satisfied (regardless of the Nt>Nx condition) so that DOx=open transistor and/
or relay with the coil not energized.
„
SoftPLC: it means that the digital output state will be controlled by the programming done in the memory area
reserved to the SoftPLC function. Refer to the SoftPLC manual for more details.
„
STO: it signalizes the STO state (Safety Stop active).
„
No F160: it signalizes that the inverter is not disabled by F160 fault (Safety Stop Relay).
„
No Alarm: it means that the inverter is not in the alarm condition.
