2.6 Dir. A
Choice of signal of
direction control for Control
A
033 Dig.Inp. Dir.
– remote direction of rotation
control (from device's Digital Inputs - see par. 2.8)
034 Keyb. Dir.
– local direction of rotation control
from the control panel
034 Keyb.
YES
2.7 Dir. B
Choice of signal of
direction control for Control
B
as above
033
Dig.Inp. Dir
YES
2.8 Remote Start
Variant of START/STOP
remote control
0
– DI1 = START/STOP, DI2 = direction
1
– DI1 = START RIGHT, DI2 = START LEFT
2
– rising edge DI1 = START,
falling edge DI2 = STOP
3
– same as above, additionally DI3 = direction
4
– DI1 = START/STOP
See table 4.1 in section 4.2.3
0
YES
2.9 Ref.Torq.A
Torque referencing-unit for
Control A
144 Reference A0 ... 146 Reference A2
–
referencing maximum torque by a signal from analog
input
147 100.0%
- maximum torque 100%
148 Reference RC
– torque calculated by internal
reeler calculator
See also par. 1.43 and par. 1.44
147 100.0 %
YES
2.10 Ref.Torq.B
Torque referencing-unit for
Control B
as above
100.0 %
YES
2.11 Ref. min
Referenced frequency
which corresponds to 0%
of the referencing-unit
- 550.0 ... 550.0 Hz
0.0 Hz
YES
2.12 Ref. max
Ref. frequency which
corresponds to 100% of
the referencing-unit
0 ... 550.0 Hz
Note: see also par. 1.40
50.0 Hz
YES
2.13 f stop
Minimal absolute value of
referenced frequency
0.0 ... 550.0 Hz
0.5 Hz
YES
2.14 Use f stop
Stopping when
f < par 2.13
YES –
device will stop, if referenced f is lower than
minimum determined by par 2.13
NO
– device will only limit frequency to par 2.13
NO
YES
2.15 Start LoRST
Deleting Signal of Local
Start
YES
– after switching control to local (from panel)
device will stay stopped (or will stop) independently
of whether the key START has been pressed before
NO
– device remembers pressing of START button
and will start immediately after changing control to
local
YES
YES
2.16 Ref. delay
Ref-unit switching on delay 0.0 ... 12.0 s
0.0 s
YES
2.18 Autostart block
Blockade of autostart
Makes it possible to blockade the frequency
converter autostart function:
000 No
– blockade of autostart is
inactive
001 Yes
– blockade of autostart is
active
The parameter is available from software version
12.63.
