211 Jog ramp time (JOG RAMP TIME)
Settings:
0.15 - 3600.00 sec.
60.00 sec.
H
3.00 sec.
Function:
The jog ramp time is the acceleration/deceleration
time from 0 Hz to the rated motor frequency f
(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.
3.00 sec.
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.

FCM 300 Series
Description of choice:
Program the desired ramp-down time.

213 Jog frequency (JOG FREQUENCY)
[300]
Settings:
0.0 H
10.0 H
M,N
Function:
The jog frequency f
at which the FCM 300 is running when the jog
function is activated.
Description of choice:
Set the desired frequency.
214 Reference function (REF FUNCTION)
Settings:
External/preset (EXTERNAL/PRESET)
H
Sum (SUM)
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.
[5 - 360000]
If External/preset [2] is selected, it is possible to shift
[300]
between external references or preset references
via terminal 2, 3, 4, or 5 (parameter 332, 333, 334,
or 335). Preset references will be a percentage
value of the reference range.
External reference is the sum of the analogue
references, pulses and bus references.
NOTE!
If Sum is selected, one of the preset references will
always be active. If the preset references are to be
without influence, they should be set to 0 % (as in
the factory setting).
