Selection of the desired operating response to an
Eme Stop command (controller blocking)
0 = Ramp
Motor decelerates in acc. to
Eme Stop Ramp (5.11)

If
Zero Speed Lev (5.15)
is reached Main Contactor
is switched off.
1 = Torque Lim
Motor decelerates in acc. to torque limit. If
Zero
Speed Lev (5.15)
is reached Main Contactor is swit-
ched off.
2 = Coast
Main Contactor is switched off. Motor coasts to zero
speed.

settings. Response time of deceleration by
Ramp
or
Torque Lim
depends on optimization of speed con-
troller. Therefore the speed controller must be adjusted.
If

for speed
controller it’s also valid for Eme Stop command. Only
Coast
is independend on speed controller settings.
Disable Bridge 1 (9.19)
and
Disable Bridge 2 (9.20)
are
also effective during
Eme
Stop Mode
. If a bridge is dis-
abled (locked) it’s not possible to brake the drive by using
Ramp
or
Torque Lim
. Use external wiring to make sure
that bridges are enabled for braking down the drive if
necessary.
External
current / torque limitation via
analog input
or
serial communication
doesn’t have any effect to
Eme
Stop Mode
.
Without
serial communication:
Emergency Stop
from terminal is
always
valid.
Coast
from terminal will not be valid until it has been
activated using the
Coast (9.04)
parameter.
With
serial communication:
Cmd Location (2.02) = Bus:
Emergency Stop
and
Coast
via the bus are “1” active
and must be provided.
Emer
Stop
via bus
are
AND
ed; both must be provided. When
Coast
from terminal has been activated in parameter Coast
(9.04)
, then
terminal
and
Coast via bus
are
AND
ed;
both must be provided.
Cmd Location (2.02) = Key:
If the bus is functioning properly, the behaviour is as
described in
Cmd Location (2.02) = Bus
. If the bus is
malfunctioning, the
Emergency Stop
and
Coast via bus
functions will be suppressed; only the
terminal
remains
active. This enables the drive to be controlled from the
terminal without any trouble.
