5-19 Terminal 37 Safe Stop
Use this parameter to congure the Safe Torque O functionality.
A warning message makes the frequency converter coast the
motor and enables the automatic restart. An alarm message
makes the frequency converter coast the motor and requires a
manual restart (via a eldbus, Digital I/O, or by pressing [RESET]
on the LCP). When the VLT
®
PTC Thermistor Card MCB 112 is
mounted, congure the PTC options to get the full benet from
the alarm handling.
Option: Function:
converter continues without manual
reset, unless a digital input set to
[80] PTC Card 1 is still enabled.
[6] PTC 1 & Relay A This option is used when the PTC
option gates with a stop key through
a safety relay to terminal 37. Coasts
frequency converter when Safe
Torque O is activated. Manual reset
from LCP, digital input, or eldbus.
[7] PTC 1 & Relay
W
This option is used when the PTC
option gates with a stop key through
a safety relay to terminal 37. Coasts
frequency converter when Safe
Torque O is activated (terminal 37
o). When safe-stop circuit is re-
established, the frequency converter
continues without manual reset,
unless a digital input set to [80] PTC
Card 1 is still enabled.
[8] PTC 1 & Relay
A/W
This option makes it possible to use
a combination of Alarm and Warning.
[9] PTC 1 & Relay
W/A
This option makes it possible to use
a combination of Alarm and Warning.
NOTICE
Options [4] PTC 1 Alarm to [9] PTC 1 & Relay W/A are only
available when the MCB 112 is connected.
NOTICE
Selecting Auto Reset/Warning enables automatic restart
of the frequency converter.

5-3* Digital Outputs
Parameters for conguring 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 parameter 5-01 Terminal 27 Mode and set the
I/O function for terminal 29 in parameter 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
given (start/disable). There are no
warnings.
[5] Running The motor is running.
