: Motorised pot bipolar select
Adjustment range :0 or 1
Factory setting :0
0 (Positive) (Pos): The up/down pot reference is limited to
positive values (0 to 100.0%).
1 (Bipolar) (biPo.): The up/down pot reference can change
from -100% to +100%.
: Motorised pot rate
Adjustment range :0 to 250 s
Factory setting :20 s
This parameter defines the time it takes for the up/down pot
reference to change from 0 to 100.0%.
It will take twice as long to change from -100.0% to +100.0%.
Defines the potentiometer sensitivity.
: Motorised pot scale factor
Adjustment range :0 to 2.50
Factory setting :1.00
The maximum value of the up/down pot reference
automatically takes the maximum value of the parameter to
which it is assigned.
This parameter can therefore be used to adapt the maximum
value of the up/down pot reference to the maximum value
required by the application.
Example:
- The up/down reference is addressed to a preset reference.
- The maximum value of a preset reference is 32000 rpm.
- We want the maximum value of the up/down reference to
correspond to 1500 rpm.
==> 9.24
: Motorised pot destination
Adjustment range :0.00 to 21.51
Factory setting :0.00
This parameter is used to define the numerical parameter
which the up/down pot reference will control.
Example: The up/down pot reference acts as a speed
reference. The up/down pot reference can be sent to a preset
reference.
==> 9.25 = 1.21.
: Motorised pot up
Adjustment range :0 or 1
0 (Disabled) (OFF)
1 (Enabled) (On)
A digital input must be assigned to this parameter for
controlling the motorised pot up function.
: Motorised pot down
Adjustment range :0 or 1
0 (Disabled) (OFF)
1 (Enabled) (On)
A digital input must be assigned to this parameter for
controlling the motorised pot down function.
: Motorised pot reset
Adjustment range :0 or 1
Factory setting :0
0 (Disabled) (No): Reset inactive.
1 (Enabled) (RSEt): The motorised pot reference is reset to
zero.
to :Binary sum inputs
Adjustment range :0 or 1
Used to modify remotely, using a combination of digital
inputs, a parameter whose selection includes more than two
possible options.
0 (Disabled) (OFF)
1 (Enabled) (On)
9.29: Binary sum ones input.
9.30: Binary sum twos input.
9.31: Binary sum fours input.
: Binary sum output
Adjustment range :0 to 39
Used to read the decimal value of the binary sum output.
: Binary sum destination
Adjustment range :0.00 to 21.51
Factory setting :0.00
Used to define the parameter that the binary sum will control.
Any bit, switch or numerical type parameter can be assigned
to the binary sum.
: Binary sum output offset
Adjustment range :0 to 32
Factory setting :0
Used to add an offset to the binary sum output.
