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
and set the I/O function for terminal 29 in par.5-02
. These parameters
cannot be adjusted while the motor is running.
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 adjustable frequency drive is ready for operation and applies a supply signal on the control
board.
[3]
Drive ready / remote control
The adjustable frequency drive is ready for operation and is in Auto On mode.
[4]
Stand-by / no warning
The adjustable frequency drive is ready for operation. No start or stop command is been given (start/
disable). There are no warnings.
[5]
Running
The 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
The 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
or par. 1-17 has been exceeded.
[12]
Out of current range
The motor current is outside the range set in par.4-18
.
[13]
Below current, low
The motor current is lower than set in par.4-50
.
[14]
Above current, high
The motor current is higher than set in par.4-51
.
[15]
Out of speed range
The output speed is outside the range set in par.4-52
[16]
Below speed, low
The output speed is lower than the setting in par.4-52
[17]
Above speed, high
The output speed is higher than the setting in par.4-53
.
[18]
Out of feedback range
The feedback is outside the range set in par.4-56
[19]
Below feedback, low
The feedback is below the limit set in par.4-56
[20]
Above feedback, high
The feedback is above the limit set in par.4-57
[21]
Thermal warning
The thermal warning turns on when the temperature exceeds the limit in the motor, the adjustable
frequency drive, 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 timeout) via the serial communication port.
[27]
Torque limit and stop
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’.
[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
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.
[35]
External Interlock
External Interlock function has been activated via one of the digital inputs.
