Description of choice:
Maximum reference is set, if the speed of the motor is to be max. the set
value, regardless of the whether the resulting reference is greater than
the maximum reference.

Ramp type
Value:
Linear (Linear)
[0]
Sin shaped (SIN SHAPED)
[1]
Sin
2
shaped (S-SHAPED 2)
[2]
Function:
You can choose between a linear, an S-shaped and an S
2
ramp process.
Description of choice:
Select the required ramp type depending on the required acceleration/
deceleration process.
207
Ramp-up time 1
Value:
0.02 - 3600.00 sec
3.00 sec
Function:
The ramp-up time is the acceleration time from 0 Hz to the rated motor
frequency f
M,N
(parameter 104
Motor frequency, f
M,N
). It is assumed that
the output current will not reach the current limit (set in parameter 221
Current limit I
LIM
).
Description of choice:
Set the required ramp-up time.
208
Ramp-down time 1
Value:
0.02 - 3600.00 sec
3.00 sec
Function:
The ramp-down time is the deceleration time from the rated motor fre-
quency f
M,N
(parameter 104
Motor frequency, f
M,N
) to 0 Hz, provided no
overvoltage arises in the inverter because of generating operation of the
motor.
Description of choice:
Set the required ramp-down time.
209
Ramp-up time 2
Value:
0.02 - 3600.00 sec.
3.00 sec
Function:
See description of parameter 207
Ramp-up time 1
.
Description of choice:
Set the required ramp-up time. Shift from ramp 1 to ramp 2 by activating
Ramp 2
via a digital input.
210
Ramp-down time 2
Value:
0.02 - 3600.00 sec.
3.00 sec
Function:
See description of parameter 208
Ramp-down time 1
.
Description of choice:
Set the required ramp-down time. Shift from ramp 1 to ramp 2 by acti-
vating
Ramp 2
via a digital input.
211
Jog ramp time
Value:
0.02 - 3600.00 sec.
3.00 sec
Function:
The jog ramp time is the acceleration/deceleration time from 0 Hz to the
rated motor frequency f
M,N
(parameter 104
Motor frequency, f
M,N
). It is
assumed that the output current will not reach the current limit (set in
parameter 221
Current limit I
LIM
).
The jog ramp time starts if a jog-signal is given via the LCP control panel,
one of the digital inputs or the serial communication port.
