Parameters 275
82.10 Quick ramp 2 accel.
time
Defines the quick ramp set 2 acceleration time.
The time required for the speed to change from zero to the
speed value defined by parameter 46.01 Speed scaling or
46.02 Frequency scaling. This ramp is effective in
speed/frequency range defined by parameters 82.07 Quick
ramp 1 upper limit and 82.12 Quick ramp 2 upper limit.
10.00
0.10...20.00 s Time 100 = 1s
82.11 Quick ramp 2 decel.
time
Defines the quick ramp set 2 deceleration time.
The time required for the speed to change from the speed
value to zero is defined by parameters 46.01 Speed scaling
or 46.02 Frequency scaling. This ramp is effective in
speed/frequency range defined by parameters 82.07 Quick
ramp 1 upper limit and 82.12 Quick ramp 2 upper limit.
10.00
0.10...20.00 s Time 100 = 1s
82.12 Quick ramp 2 upper
limit
Defines the maximum speed/frequency for the quick ramp 2.
Above this speed/frequency, the drive either uses quick ramp
2 or normal ramp time depending on selection in parameter
82.01 Quick ramp mode.
45
15...100 Hz Frequency/Speed limit 1 = 1Hz
82.20 Dry run protection Selects dry run protection mode. No action
No action Dry run protection is disabled. 0
Warning Dry run protection generates 0xD50A Running dry warning. 1
Fault Dry run protection generates D409 Outlet maximum pressure
fault.
2
Fault if running Dry run protection generates a fault if the source signal is
high when running.
3
82.21 Dry run source Selects the source for dry run protection. Under load
curve
Under load curve Activates dry run protection (parameter 37.01 ULC output
status word, bit 0).
See section User load curve (Condition monitoring) (page
52).

DI6 Digital input DI6. 6
Supervision 1 Activates dry run protection. 7
Supervision 2 Activates dry run protection. 8
Supervision 3 Activates dry run protection. 9
82.25 Soft pipe fill
supervision
Selects the drive action in case the system does not reach
the setpoint in time defined with parameter
82.26 Time-out
limit.
The time is calculated with the last reference change in
parameter 40.03 Process PID setpoint actual.
No action
No action Soft pipe fill time-out is disabled. 0
Warning Generates D405 Pipe fill-timeout warning. 1
No. Name/Value Description Def/FbEq16
