Jog is used for overriding the output frequency to the
jog frequency set in parameter 213. The ramp time can
be set in parameter 211. Jog is not active if a stop
command has been given (start-disable). Jog over-
rides stop (operating command, group 2).
Preset reference, on is used for shifting between ex-
ternal reference and preset reference. It is assumed
that External/preset [2] has been selected in parameter
214. Logic '0' = external references active; logic '1' =
one of the four preset references is active in accord-
ance with the table below.
Preset reference, lsb and Preset reference, msb
enables a choice of one of the four preset references,
in accordance with the table below.
Preset ref. msb Preset ref. lsb
Preset ref. 1
00
Preset ref. 2 0 1
Preset ref. 3 1 0
Preset ref. 4 1 1
Freeze reference - freezes the actual reference. The
frozen reference is now the point of enable/condition
for Speed up and Speed down to be used.
If speed up/down is used, the speed change always
follows ramp 2 (parameters 209/210) in the range 0 -
Ref
MAX
.
Freeze output - freezes the actual motor frequency
(Hz). The frozen motor frequency is now the point of
enable/condition for Speed up and Speed down to be
used.
If speed up/down is used, the speed change always
follows ramp 2 (parameters 209/210) in the range 0 -
f
M,N
.
NOTE
If Freeze output is active, the frequency
converter cannot be stopped via terminals
18 and 19, but only via terminal 27 (to be
programmed for Coasting stop, inverse [0]
or Reset and coasting stop, inverse [1]).
After Freeze output, the PID integrators are reset.
Speed up and Speed down are selected if digital con-
trol of the up/down speed is desired (motor potentiom-
eter). This function is only active if Freeze reference or
Freeze output has been selected. As long as there is a
logic `1` on the terminal selected for speed up, the ref-
erence or the output frequency will increase. Follow
ramp 2 (parameter 209) in the range 0 - f
MIN
.
As long as there is a logic `1` on the terminal selected
for speed down, the reference or the output frequency
will be reduced. Follow ramp 2 (parameter 210) in the
range 0 - f
MIN
.
Pulses (logic `1` minimum high for 3 ms and a mini-
mum pause of 3 ms) will lead to a change of speed of
0.1% (reference) or 0.1 Hz (output frequency).
Example:
Terminal Freeze ref./
(16)
(17)
Freeze output
No speed change 0 0
1
Speed down 0 1 1
Speed up 1 0 1
Speed down 1 1 1
The speed reference frozen via the control panel can
be changed even if the frequency converter has stop-
ped. The frozen reference will be remembered in case
of a mains drop-out.
Selection of Setup, lsb and Selection of Setup,
msb enables a choice of one of the four Setups; how-
ever, this presupposes that parameter 004 has been
set at Multi Setup.
Selection of Setup, msb/Speed up and Selection of
Setup, lsb/Speed down - together with the use of
Freeze reference or Freeze output - enable up/down
speed change.
The selection of Setup occurs in accordance with the
below verification table:
Selection of Setup Freeze ref/
(32)msb (33)lsb Freeze output
Setup 1 0 0
0
Setup 2 0 1 0
Setup 3 1 0 0
Setup 4 1 1 0
No speed change 0 0 1
Speed down 0 1 1
Speed up 1 0 1
Speed down 1 1 1
Catch-up/Slow-down is selected if the reference value
is to be increased or reduced by a programmable per-
centage value set in parameter 219.
Slow-down Catch-up
Unchanged speed 0 0
Reduced by %-value 1 0
Increased by %-value 0 1
Reduced by %-value 1 1
Ramp 2 is selected if a change between ramp 1 (pa-
rameters 207-208) and ramp 2 (209-210) is desired.
Logic '0' leads to ramp 1, while logic '1' leads to ramp
2.
