The characteristic curve is described by the coordinates x1/y1 and x2/y2, with which the analog input is evaluated.
13_ / 14_ Speed ramps 1 / 2
The ramp times refer to a setpoint change of n = 3000 rpm. Ramps t11/t21 up and t11/t21 down are effective when the setpoint is
changed. The stop ramp t13/t23 is in effect when the enable is withdrawn by pressing the STOP/RESET key or via the terminals.
130 / 140 Ramp t11 / t21 up Setting range 0 ... 2 ... 2000 [s]; Acceleration ramp
131 / 141 Ramp t11 / t21 down Setting range 0 ... 2 ... 2000 [s]; Deceleration ramp
134 / 144 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 by a binary input
(→
P601 ... P608), which is set to
the function "Ramp switchover".
135 / 145 S pattern t12 / t22
(In preparation) 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.
Effect of the S pattern:
A started S pattern is interrupted by the stop ramp t13/t23 and a changeover to
ramp t11/t21. Revoking the setpoint or a stop via the input terminals causes the
started S curve to be completed. This means the drive can still accelerate in
spite of the withdrawal of the setpoint.
136 / 146 Stop ramp t13 / t23
up = down Setting range 0 ... 2 ... 20 [s]; stop ramp when switching to the NO ENABLE
