ABB ACS380 Series - Supervision

206 Parameters
31.33 Emergency ramp
supervision delay
If parameter 31.32 Emergency ramp supervision is set to
0%, this parameter defines the maximum time an
emergency stop (mode Off1 or Off3) is allowed to take. If
the motor has not stopped when the time elapses, the
drive trips on 73B0 Emergency ramp failed, sets bit 8 of
06.17 Drive status word 2, and coasts to a stop.
If 31.32 is set to a value other than 0%, this parameter
defines a delay between the receipt of the emergency
stop command and the activation of the supervision. It is
recommended to specify a short delay to allow the speed
change rate to stabilize.
0 s
0…100 s Maximum ramp-down time, or supervision activation
delay.

32 Supervision
Configuration of signal supervision functions 1…3.
Three values can be chosen to be monitored; a warning or
fault is generated whenever predefined limits are
exceeded.
See also section Signal supervision (page 96).
32.01 Supervision status Signal supervision status word.
Indicates whether the values monitored by the signal
supervision functions are within or outside their respective
limits.
Note: This word is independent of the drive actions
defined by parameters 32.06, 32.16, 32.26, 32.36, 32.46
and 32.56.
000b
000…111b Signal supervision status word. 1 = 1
32.05 Supervision 1 function Selects the mode of signal supervision function 1.
Determines how the monitored signal (see parameter
32.07) is compared to its lower and upper limits (32.09
and 32.10 respectively). The action to be taken when the
condition is fulfilled is selected by 32.06.
Disabled
Disabled Signal supervision 1 not in use. 0
Low Action is taken whenever the signal falls below its lower
limit.
1
High Action is taken whenever the signal rises above its upper
limit.
2
Abs low Action is taken whenever the absolute value of the signal
falls below its (absolute) lower limit.
3
Abs high Action is taken whenever the absolute value of the signal
rises above its (absolute) upper limit.
