211 Jog ramp time (JOG RAMP TIME)
Settings:
0.15 - 3600.00 sec. [5 - 360000]
✭
3.00 sec. [300]
Function:
The jog ramp time is the acceleration/deceleration
time from 0 Hz to the rated motor frequency f
M,N
(parameter 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).
The jog ramp time starts if a jog signal is given via the
digital inputs or the serial communication port.
Description of choice:
Set the desired ramp time.
212 Quick stop ramp-down time
(Q STOP RAMP TIME)
Settings:
0.15 - 3600.00 sec. [5 - 360000]
✭
3.00 sec. [300]
Function:
The ramp-down time is the deceleration time from the
rated motor frequency to 0 Hz, 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).
Quick-stop is activated by means of a signal on one
of the digital input terminals (2-5), or via the serial
communication port.
Description of choice:
Program the desired ramp-down time.

207 Ramp-up time (RAMP UP TIME )
Settings:
0.15 - 3600.00 sec. [5 -360000]
✭
3.00 sec. [300]
Function:
The ramp-up time is the acceleration time from 0 Hz
to the rated motor frequency f
M,N
(parameter 104).
This presupposes that the current limit is not reached
(to be set in parameter 221).
Description of choice:
Program the desired ramp-up time.
208 Ramp-down time (RAMP DOWN TIME )
Settings:
0.15 - 3600.00 sec. [5 - 360000]
✭
3.00 sec. [300]
Function:
The ramp-down time is the deceleration time from the
rated motor frequency f
M,N
(parameter 104) to 0 Hz
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.
