Explanation of the parameters
Parameterization of MOVIPRO
®
The ramp times refer to a setpoint step change of
∆
n = 3000 rpm. The ramp takes effect
when the speed setpoint is changed and the enable is revoked via the CW/CCW termi-
nal.
P134 / P144 Ramp
t12 / t22 UP =
DOWN
Setting range: 0 – 10 – 2000 s
The following applies to this ramp: UP = DOWN and CW = CCW.
Ramps t12/t22 are activated via a binary input, which is set to the function "Ramp
switchover". For information about binary input assignment, refer to
P601 – P604 Binary
inputs DIØ2 – DIØ5
(page 108).
P135 / P145 S pat-
tern t12 / t22
Setting range: 0 / 1 / 2 / 3 (0 = off, 1 = weak, 2 = medium, 3 = strong)
The 2nd ramp (t12/ t22) of parameter sets 1 and 2 can be rounded with 3 pattern grades
to achieve a smoother acceleration of the drive.
A started S pattern is interrupted by the stop ramp t13 / t23 and a changeover to ramp
t11 / t21. Withdrawing the setpoint or a stop using the input terminals causes the started
S curve to be completed. This allows the drive to continue to accelerate despite the fact
that the setpoint has been withdrawn.
P136 / P146 stop
ramp t13 / t23
Setting range: 0 – 2 – 20 s
The stop ramp is activated by withdrawing the ENABLE terminal or by an error. For in-
formation about possible error responses, refer to
P83x Fault responses
(page 117).
P137 / P147 Emer-
gency ramp t14 /
t24
Setting range: 0 – 2 – 20 s
The emergency ramp is activated by an error. For information about possible error re-
sponses, refer to
P83x Fault responses
(page 117). The system monitors whether the
drive reaches zero speed within the set time. After the set time expires, the output stage
is inhibited and the brake applied even if zero speed has not yet been reached.
