Description:
They program the function of the digital outputs, according to the options presented previously. When the
condition declared by the function is true, the digital output will be activated.
Example: Function
Ia > Ix
When the armature current (Ia) is higher that the value set in P0290 (Ix), we will have the DOx programmed for
this function activated (saturated transistor and/or relay with coil energized). Otherwise, the DOx will be
deactivated (transistor cut off and/or relay with coil de-energized).
Below are some additional notes regarding the digital and relay output functions.
Not used:
Digital outputs programmed for “Not Used” will remain indefinitely in the idle status, that is, with the
transistor cut off and/or relay with the coil de-energized.
Zero Speed:
Function that indicates if the motor speed is below the value set in P0291.
Torque > Tx and Torque < Tx:
It actuates according to the value of P0009 (Motor Torque) and P0293 (Torque
Tx)
Remote:
Function that will activate the digital output programmed when the converter is operating in the
Remote status.
Run:
Indicates if the CTW900 is operating with programmed reference (even if that is zero), and is equivalent to
the ‘Run’, ‘Accelerating’ and ‘Decelerating’ status of the converter.
Ready:
Activates the digital output when the converter status is ‘Ready’.
Without Fault:
Keeps the output activated while no faults are present on the converter.
With F003:
Signals the occurrence of undervoltage in the line (fault F003).
With F072:
Signals the occurrence of overload on the motor (fault F072).
With F077:
Signals the occurrence of the Stall Protection (fault F077).
Reference 4 to 20 mA Ok:
It means the reference in current (option 4 to 20 mA) of the analog inputs is within
the correct range.
Content of P0695:
Allows the digital output status to be controlled by parameter P0695, which is written via
network. For further details about this function, refer to the Modbus Communication Manual
Forward Direction:
Function that will activate the digital output while the motor is spinning in the forward
direction.
With Fault:
Function that will activate the digital output when any fault is present on the converter.
Time Enabled > Hx:
Activates the digital output when the value of P0043 exceeds the value set in P0294.
SoftPLC:
Allows the digital output status to be controlled by the programming made in the memory area
reserved for the SoftPLC function. For further details, refer to the SoftPLC Manual.
