207 Ramp-up time 1
(ramp-up time 1)
Value:
0.02 - 3600.00 sec
3.00 sec (VLT 2803-2875)
10.00 sec (VLT 2880-2882)
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 (VLT 2803-2875)
10.00 sec (VLT 2880-2882)
Function:
The ramp-down time is the deceleration time from the
rated motor frequency f
M,N
(parameter 104 Motor fre-
quency, 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 (VLT 2803-2875)
10.00 sec (VLT 2880-2882)
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 (VLT 2803-2875)
10.00 sec (VLT 2880-2882)
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 (VLT 2803-2875)
10.00 sec (VLT 2880-2882)
Function:
The jog ramp time is the acceleration/deceleration
time from 0 Hz to the rated motor frequency f
M,N
(pa-
rameter 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
).
