Examples
Different parameter sets can be used to easily change the
setup of a AC drive to adapt quickly to different application
requirements. For example when
• a process needs optimized settings in different stages of
the process, to
- increase the process quality
- increase control accuracy
- lower maintenance costs
- increase operator safety
With these settings a large number of options are available.
Some ideas are given here:
Multi frequency selection
Within a single parameter set the 7 preset references can be
selected via the digital inputs. In combination with the
parameter sets, 28 preset references can be selected using all
5 digital inputs: DigIn1, 2 and 3 for selecting preset
reference within one parameter set and DigIn 4 and DigIn 5
for selecting the parameter sets.
Bottling machine with 3 different products
Use 3 parameter sets for 3 different Jog reference speeds
when the machine needs to be set up. The 4th parameter set
can be used for “normal” remote control when the machine
is running at full production.
Product changing on winding machines
If a machine has to change between 2 or 3 different products
e.g. winding machine with different gauges of thread, it is
important that acceleration, deceleration times, Max Speed
and Max Torque are adapted. For each thread size a different
parameter set can be used.
Manual - automatic control
If in an application something is filled up manually and then
the level is automatically controlled using PID regulation,
this is solved using one parameter set for the manual control
and one for the automatic control.
7.1.1 One motor and one parameter
set
This is the most common application for pumps and fans.
Once default motor M1 and parameter set A have been
selected:
1. Enter the settings for motor data.
2. Enter the settings for other parameters e.g. inputs and
outputs
7.1.2 One motor and two parameter
sets
This application is useful if you for example have a machine
running at two different speeds for different products.
Once default motor M1 is selected:
1. Select parameter set A in menu [241].
2. Enter motor data in menu [220].
3. Enter the settings for other parameters e.g. inputs and
outputs.
4. If there are only minor differences between the settings
in the parameter sets, you can copy parameter set A to
parameter set B, menu [242].
5. Enter the settings for parameters e.g. inputs and outputs.
7.1.3 Two motors and two parameter
sets
This is useful if you have a machine with two motors that
can not run at the same time, such as a cable winding
machine that lifts up the reel with one motor and then turns
the wheel with the other motor.
One motor must stop before changing to an other motor.
1. Select parameter set A in menu [241].
2. Select motor M1 in menu [212].
3. Enter motor data and settings for other parameters e.g.
inputs and outputs.
4. Select parameter set B in menu [241].
5. Select M2 in menu [212].
6. Enter motor data and settings for other parameters e.g.
inputs and outputs.
7.1.4 Autoreset at trip
For several non-critical application-related failure
conditions, it is possible to automatically generate a reset
command to overcome the fault condition. The selection
can be made in menu [250]. In this menu the maximum
number of automatically generated restarts allowed can be
set, see menu [251], after this the AC drive will stay in fault
condition because external assistance is required.
Note: Do not change motor data in parameter set B.
