207 Ramp-up time 1
(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
(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 frequency 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
(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
(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 activating
Ramp 2
via a digital input.
211 Jog ramp time
(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.
