The digital outputs can be programmed with these functions:
[0]
No operation
Default for all digital outputs and relay outputs
[1]
Control ready
The control board receives supply voltage.
[2]
Drive ready
The frequency converter is ready for operation and applies a supply signal on the control board.
[3]
Drive ready / remote control
The frequency converter is ready for operation and is in Auto On mode.
[4]
Stand-by / no warning
The frequency converter is ready for operation. No start or stop command is been given (start/
disable). There are no warnings.
[5]
Running
Motor is running.
[6]
Running / no warning
The output speed is higher than the speed set in par. 1-81
Min Speed for Function at Stop [RPM]
.
The motor is running and there are no warnings.
[8]
Run on reference / no warning
Motor runs at reference speed.
[9]
Alarm
An alarm activates the output. There are no warnings.
[10]
Alarm or warning
An alarm or a warning activates the output.
[11]
At torque limit
The torque limit set in par. 4-16 has been exceeded.
[12]
Out of current range
The motor current is outside the range set in par. 4-18.
[13]
Below current, low
Motor current is lower than set in par. 4-50.
[14]
Above current, high
Motor current is higher than set in par. 4-51.
[15]
Out of speed range
Output speed is outside the range set in par. 4-52 and 4-53.
[16]
Below speed, low
Output speed is lower than the setting in par. 4-52.
[17]
Above speed, high
Output speed is higher than the setting in par. 4-53.
[18]
Out of feedback range
Feedback is outside the range set in par. 4-56 and 4-57.
[19]
Below feedback low
Feedback is below the limit set in par. 4-56 Warning Feedback Low.
[20]
Above feedback high
The feedback is above the limit set in par. 4-57
Warning Feedback High
.
[21]
Thermal warning
The thermal warning turns on when the temperature exceeds the limit in the motor, the frequency
converter, the brake resistor, or the thermistor.
[25]
Reverse
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.
[26]
Bus OK
Active communication (no time-out) via the serial communication port.
[27]
Torque limit and stop
Used in performing a coasting stop and in torque limit condition. If the frequency converter has
received a stop signal and is at the torque limit, the signal is Logic ‘0’.
[28]
Brake, no warning
The brake is active and there are no warnings.
[29]
Brake ready, no fault
The brake is ready for operation and there are no faults.
[30]
Brake fault (IGBT)
The output is Logic ‘1’ when the brake IGBT is short-circuited. Use this function to protect the
frequency converter if there is a fault on the brake modules. Use the output/relay to cut out the
main voltage from the frequency converter.
[35]
External Interlock
External Interlock function has been activated via one of the digital inputs.
[40]
Out of ref range
[41]
Below reference low
[42]
Above reference high
[45]
Bus Ctrl
[46]
Bus Ctrl 1 if timeout
[47]
Bus Ctrl 0 if timeout
[55]
Pulse output
[60]
Comparator 0
See par. group 13-1*. If Comparator 0 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[61]
Comparator 1
See par. group 13-1*. If Comparator 2 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
