Emergency stop
The emergency stop signal is connected to the input selected by parameter
. An emergency stop can also be generated through fieldbus
(parameter
, bits 0…2).
The mode of the emergency stop is selected by parameter
. The following modes are available:
• Off1: Stop along the standard deceleration ramp defined for the particular
reference type in use
• Off2: Stop by coasting
• Off3: Stop by the emergency stop ramp defined by parameter
With Off1 or Off3 emergency stop modes, the ramp-down of the motor speed can be
supervised by parameters
and
.
Notes:
• The installer of the equipment is responsible for installing the emergency stop
devices and all additional devices needed for the emergency stop function to fulfill
the required emergency stop categories. For more information, contact your local
ABB representative.
• After an emergency stop signal is detected, the emergency stop function cannot
be canceled even though the signal is canceled.
• If the minimum (or maximum) torque limit is set to 0%, the emergency stop
function may not be able to stop the drive.
• Speed and torque reference additives (parameters
and
) and reference ramp shapes (
) are ignored in case of
emergency ramp stops.

Motor thermal protection
The control program features two separate motor temperature monitoring functions.
The temperature data sources and warning/trip limits can be set up independently for
each function.
