Programming
If closed loop has been selected the maximum reference
cannot be set higher than the maximum feedback
(parameter 415).
Description of choice:
Set the desired value.

207 Ramp-up time 1
Value:
0.15-3600.00 s
3.00 s
Function:
The ramp-up time is the acceleration time from 0 Hz to
the rated motor frequency f
presupposes that the current limit is not reached (to be set
in parameter 221).
Illustration 3.17
Description of choice:
Program the desired ramp-up time.
208 Ramp-down time 1
Value:
0.15-3600.00 s
3.00 s
Function:
The ramp-down time is the deceleration time from the
rated motor frequency f
provided there is no over-voltage in the inverter because
of regenerative operation of the motor, and the current
limit is not reached (to be set in parameter 221).
Description of choice:
Program the desired ramp-down time.
209 Ramp-up time 2
Value:
0.15-3600.00 s
3.00 s
Function:
The ramp-up time is the acceleration time from 0 Hz to
the rated motor frequency f

210 Ramp-down time 2
Value:
0.15-3600.00 s

3.00 s
Function:
The ramp-down time is the deceleration time from the
rated motor frequency f
provided there is no over-voltage in the inverter because
of regenerative operation of the motor, and the current
limit is not reached (to be set in parameter 221).

211 Jog ramp time
Value:
0.15-3600.00 s
3.00 s
Function:
The jog ramp time is the acceleration/deceleration time
from 0 Hz to the rated motor frequency f
104), provided there is no over-voltage in the inverter
because of regenerative operation of the motor, and the
current limit is not reached (to be set in parameter 221).

Illustration 3.18
The jog ramp time starts if a jog signal is given via the
digital inputs or the serial communication port.
