Parameters
3.6.3 5-3* Digital Outputs
Parameters for configuring the output functions for the
output terminals. The 2 solid-state digital outputs are
3 3
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.

VLT HVAC Basic Drive Programming Guide
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 1-81 Min Speed for Function at
Stop [RPM]. 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.
Motor Mode or 4-13 Motor Speed High
Limit [RPM] has been exceeded.
The motor current is outside the range set
in 4-18 Current Limit.
The motor current is lower than set in
4-50 Warning Current Low.
The motor current is higher than set in
4-51 Warning Current High.
The output speed is lower than the
setting in 4-52 Warning Speed Low.
The output speed is higher than the
setting in 4-53 Warning Speed High.
The feedback is outside the range set in
4-56 Warning Feedback Low and
4-57 Warning Feedback High.
The feedback is below the limit set in
4-56 Warning Feedback Low.

The feedback is above the limit set in
4-57 Warning Feedback High.
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, 24V
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 main
voltage from the adjustable frequency
drive.
External Interlock function has been
activated via one of the digital inputs.
See parameter group 13-1*. If Comparator
0 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
3 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
