5-3* Digital Outputs - Danfoss VLT Midi Drive FC 280 Programming Manual

Parameter Descriptions
5-19 Terminal 37/38 Safe Torque Off
Use this parameter to set up the STO functionality. Warning
makes the frequency converter coast and enables automatic
restart. Alarm makes the frequency converter coast and requires
a manual restart.
Option: Function:
[1] Safe Torque Off Coast the frequency converter when Safe
*
Alarm Torque Off is activated. Manual reset from
LCP, digital input, or fieldbus. This alarm
can no longer be reset by automatic
reset mode of parameter 14-20 Reset
Mode in software 1.2 and further versions.
[3] Safe Torque Off Coast the frequency converter when Safe
Warning Torque Off is activated (terminal 37 and
terminal 38 off). When Safe Torque Off
circuit is reestablished, the frequency
converter continues without manual
reset.

4.6.2 5-3* Digital Outputs

The 2 solid-state digital outputs are common for terminal
27. Set the I/O function for terminal 27 in
parameter 5-01 Terminal 27 Mode.
Terminal 42 can also be configured as digital outputs.
NOTICE
These parameters cannot be adjusted while the motor is
running.
5-30 Digital Outputs
[0] No operation Default for all digital outputs.
*
[1] Control ready The control card is ready.
[2] Drive ready The frequency converter is ready for
operation and applies a supply signal on
the control board.
[3] Drive ready / The frequency converter is ready for
remote control operation and is in auto-on mode.
[4] Stand-by / no Ready for operation. No start or stop
warning command is given (start/disable). No
warnings are active.
[5] Running The motor is running and shaft torque is
present.
[6] Running / no The output speed is higher than the
warning speed set in parameter 1-81 Min Speed for
Function at Stop [RPM]. The motor is
running and there are no warnings.
[7] Run in range / The motor is running within the
no warning programmed current and speed ranges
set in parameter 4-50 Warning Current Low
to parameter 4-51 Warning Current High.
There are no warnings.

The motor runs at reference speed. No
warnings.
An alarm activates the output. There are
no warnings.
An alarm or a warning activates the
output.
The torque limit set in
parameter 4-16 Torque Limit Motor Mode
or parameter 4-17 Torque Limit Generator
Mode has been exceeded.
The motor current is outside the range
set in parameter 4-18 Current Limit.
The motor current is lower than set in
parameter 4-50 Warning Current Low.
The motor current is higher than set in
parameter 4-51 Warning Current High.
Output frequency is outside the
frequency range.
The output speed is lower than the
setting in parameter 4-40 Warning Freq.
Low.
The output speed is higher than the
setting in parameter 4-41 Warning Freq.
High.
The feedback is outside the range set in
parameter 4-56 Warning Feedback Low and
parameter 4-57 Warning Feedback High.
The feedback is below the limit set in
parameter 4-56 Warning Feedback Low.
The feedback is above the limit set in
parameter 4-57 Warning Feedback High.
The thermal warning turns on when the
temperature exceeds the limit in the
motor, the frequency converter, the brake
resistor, or the thermistor.
The frequency converter is ready for
operation, and there is no overtem-
perature warning.
The frequency converter is ready for
operation and is in auto-on mode. There
is no overtemperature warning.
The frequency converter is ready for
operation and the mains voltage is within
the specified voltage range (see chapter
General Specifications in the design guide).
The motor runs (or is ready to run)
clockwise when logic=0 and counter-
clockwise when logic=1. The output
changes when the reversing signal is
applied.
Active communication (no timeout) via
the serial communication port.
