The
Operation mode
474
of the motor potentiometer function defines the behavior
of the function at various operating points of the frequency inverter.
Operation mode
474
Function
0 - non-storing
In the operation mode motor potentiometer non-
storing (not Latching), the drive goes to the set mini-
mum reference value at each start.
1 - latching
In the operation mode storing (latching) the motor
goes to the reference value selected before the
switch-off at the start. The reference value is also
stored when the device is switched off.
2 - taking over
The operation mode Motorpoti taking over is to be
used for the data set change-over of the reference
value channel. The current reference value is used
when the motorpoti function is activated.
3 - taking over and storing
This operation mode combines the behavior in op-
eration mode 1 and 2.
13.10.1 Motorpoti (MP)
The Function “Motorpoti (MP)” is to be parameterized via the parameter
Reference
frequency source
475
or
Reference percentage source
476
.
Frequency reference channel
Via the digital control inputs, the required functions
Frequency motorpoti up
62
and
Frequency motorpoti down
63
are triggered.
Limitation of the reference values is affected via parameters
Minimum frequency
418
and
Maximum frequency
419
.
Reference percentage channel
Via the digital control inputs, the required functions
Percentage motorpoti up
72
and
Percentage motorpoti down
73
are triggered. Limitation of the reference values is
affected via parameters
Minimum percentage
518
and
Maximum percentage
519
.
13.10.2 Motorpoti (KP)
The function „Motorpoti (KP)“ is only available in the reference frequency channel.
The function and its link to other reference value sources can be selected via pa-
rameter
Reference frequency source
475
.
Via the keys of the control unit KP 500, the required functions
Frequency motorpoti
up
62
and
Frequency motorpoti down
63
are triggered.
Limitation of the reference values is affected via parameters
Minimum frequency
418
and
Maximum frequency
419
.
Control is performed as described in chapter
„Control unit KP500, Controlling the Motor via the control unit“.
If the function Motorpoti (KP) is activated, „inPF“ will be dis-
played for clockwise (forward) direction of rotation and „inPr“ for
anticlockwise (reverse) direction of rotation.
