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:
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 Off is activated. Manual reset
from LCP, digital input, or fieldbus.
[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 Off is activated (terminal 37
off). 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.

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.

3.7.3 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
parameter 5-01 Terminal 27 Mode
and set the
I/O function for terminal 29 in
. 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
