3.7.5 5-3* Digital Outputs
Parameters for configuring the output functions for the output terminals. The two solid state digital outputs are common for terminals 27 and 29. Set the
I/O function for terminal 27 in par.5-01
cannot be adjusted while the motor is running.

and set the I/O function for terminal 29 in par.5-02
The digital outputs can be programmed with these functions:
Default for all digital outputs and relay outputs
The control board receives supply voltage.
The adjustable frequency drive is ready for operation and applies a supply signal on the control
board.
The adjustable frequency drive is ready for operation and is in Auto On mode.
The adjustable frequency drive is ready for operation. No start or stop command is been given (start/
disable). There are no warnings.
The motor is running.
The output speed is higher than the speed set in par.1-81
The motor is running and there are no warnings.
The motor runs at reference speed.
An alarm activates the output. There are no warnings.
An alarm or a warning activates the output.
The torque limit set in par.4-16
The motor current is outside the range set in par.4-18
The motor current is lower than set in par.4-50
The motor current is higher than set in par.4-51
The output speed is outside the range set in par.4-52
Speed High
.
The output speed is lower than the setting in par.4-52
The output speed is higher than the setting in par.4-53
The feedback is outside the range set in par.4-56
Feedback High
.
The feedback is below the limit set in par.4-56
The feedback is above the limit set in par.4-57
The thermal warning turns on when the temperature exceeds the limit in the motor, the adjustable
frequency drive, the brake resistor, or the thermistor.
Reversing. Logic '1' =
relay activated, 24 V DC when CW rotation of the motor. Logic '0' = relay not
activated, no signal, when CCW rotation of the motor.
Active communication (no timeout) via the serial communication port.
Use in performing a coasting stop and in torque limit condition. If the adjustable frequency drive
has received a stop signal and is at the torque limit, the signal is Logic '0'.
The brake is active and there are no warnings.
The brake is ready for operation and there are no faults.
The output is Logic '1' when the brake IGBT is short-circuited. Use this function to protect the
adjustable frequency drive if there is a fault on the brake modules. Use the output/relay to cut out
the AC line voltage from the adjustable frequency drive.
External Interlock function has been activated via one of the digital inputs.
