Danfoss VLT Brook Crompton Motor FCM 300, Design Manual

Page: 47 / 102

Description of choice:
Set the desired ramp time.
212 Quick stop ramp-down time
Value:
0.15-3600.00 s [5-360000]
3.00 s [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 communi-
cation port.
Description of choice:
Program the desired ramp-down time.
213 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
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 [0] Sum is selected, one of the adjusted preset references
(parameters 215-216) is added as a percentage of the
maximum possible reference.
If
[2] External/preset is selected, it is possible to shift
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.
215 Preset reference 1
216 Preset reference 2
Value:
-100.00%-+100.00% [-10000-+10000]
% of the reference range/external reference
0.00% [0]
Function:
Two different preset references can be programmed in
parameters 215-216.
The preset reference is stated as a percentage of the value
Ref
MAX
or as a percentage of the other external references,
depending on the choice made in parameter 214. If a
Ref
MIN
≠ 0 has been programmed, the preset reference as a
percentage will be calculated on the basis of the difference
between Ref
MAX
and Ref
MIN
, following the value is added to
Ref
MIN
.
Description of choice:
Set the fixed reference(s) that is/are to be the options.
To use the fixed references, it is necessary to have selected
Preset ref. enable on terminal 2, 3, 4, or 5 (parameters 332
- 335).
Choices between fixed references can be made by
activating terminal 2, 3, 4, or 5 - see
Table 3.8 .

219 Catch up/slow down value
Value:
0.00-100.00% [0-10000]
0.00% [0]
Function:
This parameter enables the entry of a percentage value
(relative) which will either be added to or deducted from
the actual reference.
Description of choice:
If Catch up has been selected via one of the terminals 2, 3,
4, or 5 (parameters 332 - 335), the percentage (relative)
value selected in parameter 219 will be added to the total
reference.
If Slow down has been selected via one of the terminals 2,
3, 4, or 5 (parameters 332 - 335), the percentage (relative)
value selected in parameter 219 will be deducted from the
total reference.
221 Current limit for motor mode
Value:
Min. limit (XX.X) - max. limit (XXX.X)
in% of I

[XXX - XXXX]
