Danfoss vlt FC 102 Programming Guide

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:
[1] Safe Stop
Alarm
Coasts the frequency converter
when Safe Torque O is activated.
Manual reset from LCP, digital input,
or eldbus.
[3] Safe Stop
Warning
Coasts the frequency converter
when Safe Torque O is activated
(terminal 37 o). When the Safe
Torque O circuit is re-established,
the frequency converter continues
without manual reset.
[4] PTC 1 Alarm Coasts the frequency converter
when Safe Torque O is activated.
Manual reset from LCP, digital input,
or eldbus.
[5] PTC 1 Warning Coasts the frequency converter
when Safe Torque O is activated
(terminal 37 o). When the Safe
Torque O circuit is re-established,
the frequency 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 VLT
®
PTC Thermistor Card MCB 112 gates
with a stop key through a safety
relay to terminal 37. Coasts the
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 VLT
®
PTC Thermistor Card MCB 112 gates
with a stop key through a safety
relay to terminal 37. Coasts the
frequency converter when Safe
Torque O is activated (terminal 37
o). When the Safe Torque O
circuit is re-established, the
frequency converter continues
without manual reset, unless a
digital input set to [80] PTC Card 1
is still enabled.

the alarm handling.
Option: Function:
[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.
