6.6.4 5-3* Digital Outputs

Parameters for configuring the output functions for the
6 6
output terminals. The 2 solid-state digital outputs are
common for terminals 27 and 29. Set the I/O function for
terminal 27 in parameter 5-01 Terminal 27 Mode, and set
the I/O function for terminal 29 in parameter 5-02 Terminal
29 Mode. Digital outputs appear if parameter 5-01 Terminal
27 Mode or parameter 5-02 Terminal 29 Mode are set to
output.
NOTICE!
These parameters cannot be adjusted while the motor is
running.

Function:
The digital outputs can be programmed
with these functions:
Default for all digital outputs and relay
outputs
The control board receives supply voltage.
The frequency converter is ready for
operation and applies a supply signal on
the control board.
The frequency converter is ready for
operation and is in Auto On mode.
The frequency converter 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 parameter 1-81 Min Speed for
Function at Stop [RPM]. The motor is
running and there are no warnings.
The motor runs at reference speed.

[8] Run in The motor runs in speed range.
range / no
warning
[9] Alarm An alarm activates the output. There are
no warnings.
[10] Alarm or An alarm or a warning activates the
warning output.
[11] At torque The torque limit set in
limit parameter 4-16 Torque Limit Motor Mode or
parameter 1-17 Voltage filter time const. has
been exceeded.
[12] Out of current The motor current is outside the range set
range in parameter 4-18 Current Limit.
[13] Below The motor current is lower than set in
current, low parameter 4-50 Warning Current Low.
[14] Above The motor current is higher than set in
current, high parameter 4-51 Warning Current High.
[15] Out of speed The output speed is outside the range set
range in parameter 4-52 Warning Speed Low and
parameter 4-53 Warning Speed High.
[16] Below speed, The output speed is lower than the setting
low in parameter 4-52 Warning Speed Low.
[17] Above speed, The output speed is higher than the
high setting in parameter 4-53 Warning Speed
High.
[18] Out of The feedback is outside the range set in
feedback parameter 4-56 Warning Feedback Low and
range parameter 4-57 Warning Feedback High.
[19] Below The feedback is below the limit set in
feedback low parameter 4-56 Warning Feedback Low.
[20] Above The feedback is above the limit set in
feedback high parameter 4-57 Warning Feedback High .
[21] Thermal The thermal warning turns on when the
warning 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 Use in performing a coasting stop and in
and stop 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 The brake is active and there are no
warning warnings.
[29] Brake ready, The brake is ready for operation and there
no fault are no faults.
[30] Brake fault The output is Logic '1' when the brake
(IGBT) IGBT is short-circuited. Use this function to
