5-19 Terminal 37 Safe Stop
Option: Function:
[7] PTC 1 &
Relay W This choice is used when the PTC option is
gated together with a Stop button through a
Safety relay to T-37. Coasts frequency
converter when safe stop is activated (T-37
off). When safe stop circuit is reestablished,
the frequency converter will continue without
manual reset, unless a Digital Input set to
PTC Card 1 [80] is (still) enabled. Choice 7 is
only available when the MCB 112 PTC
Thermistor Card is connected.
[8] PTC 1 &
Relay A/W This choice makes it possible to use a
combination of Alarm and Warning. Choice 8
is only available when the MCB 112 PTC
Thermistor Card is connected.
[9] PTC 1 &
Relay W/A This choice makes it possible to use a
combination of Alarm and Warning. Choice 9
is only available when the MCB 112 PTC
Thermistor Card is connected.
Choises 4 - 9 are only available when the MCB 112 PTC
Thermistor Card is connected.
NOTE
When Auto Reset/Warning is selected the frequency
converter opens up for automatic restart.

3.7.4 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 frequency converter is ready for
operation and applies a supply signal on
the control board.
[3] Drive ready /
remote
control The frequency converter is ready for
operation and is in Auto On mode.
[4] Stand-by / no
warning The frequency converter 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 .
[15] Out of speed
range The output speed is outside the range set
in
4-52 Warning Speed Low and
4-53 Warning Speed 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 .
