7.5 Change over to ramp 2 during operaon
Two dierent ramps can be parameterised for the frequency setpoint. The change-over to the
ramp 2 can be iniated manually or automacally.
Details
For ramp 2, the acceleraon me 2 set in 0x2919 (P222.00) and the deceleraon me 2 set in
0x291A (P223.00) apply.
The change-over to ramp 2 is eected automacally if the frequency setpoint (absolute value)
≥ auto-changeover threshold 0x291B (P224.00).

The "Acvate ramp 2" 0x2631:039 (P400.39) funcon serves to manually acvate the acceler-
aon me 2 and the deceleraon me 2 .

(P222.00)
Acceleraon me 2
(Accelerat.me 2)
0.0 ... [5.0] ... 3600.0 s
Acceleraon me 2 for the operang mode "MS: Velocity mode".
•
The acceleraon me set refers to the acceleraon from standsll to
the maximum frequency set. In the case of a lower setpoint selecon,
the actual acceleraon me is reduced accordingly.
•
The acceleraon me 2 is acve if the frequency setpoint (absolute
value) ≥ auto switching threshold 0x291B (P224.00) or the trigger
assigned to the funcon "Acvate ramp 2" in 0x2631:039 (P400.39) =
TRUE.
•
The acceleraon me 2 is also used for changing the MOP setpoint
generated by the "motor potenometer" funcon.
•
Seng is not eecve in the operang mode 0x6060 (P301.00) =

(P223.00)
Deceleraon me 2
(Decelerat.me 2)
0.0 ... [5.0] ... 3600.0 s
Deceleraon me 2 for the operang mode "MS: Velocity mode".
•
The deceleraon me set refers to the deceleraon from the maxi-
mum frequency set to standsll. In the case of a lower actual fre-
quency, the actual deceleraon me is reduced accordingly.
•
The deceleraon me 2 is acve if the frequency setpoint (absolute
value) ≥ auto change-over threshold 0x291B (P224.00) or the trigger
assigned to the funcon "Acvate ramp 2" in 0x2631:039 (P400.39) =
TRUE.
•
The deceleraon me 2 is also used for changing the MOP setpoint
generated by the "motor potenometer" funcon.

Seng is not eecve in the operang mode 0x6060 (P301.00) =

0x291B
(P224.00)
Auto-changeover threshold of ramp 2
(Ramp 2 thresh.)
0.0 ... [0.0] ... 599.0 Hz
Threshold for the automac change-over to acceleraon me 2 and
deceleraon me 2.
•
The change-over is eected if the frequency setpoint (absolute value)
≥ auto change-over threshold.
•
With the seng 0, the automac change-over funcon is deacvated.
