210 Ramp-down time 2
(RAMP DOWN TIME 2)
Value:
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.
Shift from ramp 1 to ramp 2 by activating
ramp 2 via a digital input
211 Jog ramp time
(JOG RAMP TIME)
Value:
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)
Value:
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.
213 Jog frequency
(JOG FREQUENCY)
Value:
0.0 HZ - parameter 202
[0 -]
✭
10.0 HZ
[100]
Function:
The jog frequency f
JOG
is the fixed output
frequency at which the FC motor is running when
the jog function is activated.
Description of choice:
Set the desired frequency.
214 Reference function
(REF FUNCTION)
Value:
✭
Sum (SUM)
[0]
External/preset (EXTERNAL/PRESET)
[2]
Function:
It is possible to define how the preset references
are to be added to the other references. For
this purpose,
Sum
is used. It is also possible -
by using the
External/preset
function - to select
whether a shift between external references and
preset references is desired.
Description of choice:
If
Sum
[0] is selected, one of the adjusted preset
references (parameters 215-216) is added as a
percentage of the maximum possible reference.
