Terminal X46/1 Digital Input - Danfoss VLT AutomationDrive FC 302 Programming Manual

Parameter Descriptions
5-19 Terminal 37 Safe Stop
Use this parameter to configure the Safe Torque Off 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 fieldbus, Digital I/O, or by pressing [RESET]
®
on the LCP). When the VLT PTC Thermistor Card MCB 112 is
mounted, configure the PTC options to get the full benefit from
the alarm handling.
Option: Function:
to terminal 37. Coasts the frequency
converter when Safe Torque Off is
activated. Manual reset from LCP,
digital input, or fieldbus.
[7] PTC 1 & Relay
This option is used when the VLT
W
PTC Thermistor Card MCB 112 gates
with a stop key through a safety relay
to terminal 37. Coasts the frequency
converter when Safe Torque Off is
activated (terminal 37 off). When the
Safe Torque Off 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 This option makes it possible to use a
A/W combination of alarm and warning.
[9] PTC 1 & Relay This option makes it possible to use a
W/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.
