3.6.3 5-3* Digital Outputs
Parameters for configuring the output functions for the
output terminals. The 2 solid-state digital outputs are
common for terminals 27 and 29. Set the I/O function for
terminal 27 in
5-01 Terminal 27 Mode
and set the I/O
function for terminal 29 in
5-02 Terminal 29 Mode
. 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
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
4-16 Torque Limit
Motor Mode
or
4-13 Motor Speed High
Limit [RPM]
has been exceeded.
[12]
Out of current
range
The motor current is outside the range set
in
4-18 Current Limit
.
[13]
Below current,
low
The motor current is lower than set in
4-50 Warning Current Low
.
[14]
Above current,
high
The motor current is higher than set in
4-51 Warning Current High
.
[16]
Below speed,
low
The output speed is lower than the
setting in
4-52 Warning Speed Low
.
[17]
Above speed,
high
The output speed is higher than the
setting in
4-53 Warning Speed High
.
[18]
Out of
feedback
range
The feedback is outside the range set in
4-56 Warning Feedback Low
and
4-57 Warning Feedback High
.
[19]
Below
feedback low
The feedback is below the limit set in
4-56 Warning Feedback Low
.
[20]
Above
feedback high
The feedback is above the limit set in
4-57 Warning Feedback High
.
[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, 24V
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 main
voltage from the adjustable frequency
drive.
[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
[60]
Comparator 0
See parameter group 13-1*. If Comparator
0 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[61]
Comparator 1
See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[62]
Comparator 2
See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[63]
Comparator 3
See parameter group 13-1*. If Comparator
3 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
