Emotron FDU 2.0 Variable Speed Drive

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.
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.
Note: Do not change motor data in parameter set B.
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 VSD will stay in fault condition because
external assistance is required.
Example
The motor is protected by an internal protection for thermal
overload. When this protection is activated, the VSD should
wait until the motor is cooled down enough before resuming
normal operation. When this problem occurs three times in
a short period of time, external assistance is required.
The following settings should be applied:
• Insert maximum number of restarts; set menu [251] to
3.
• Activate Motor I 2 t to be automatically reset; set menu
[25A] to 300 s.
• Set relay 1, menu [551] to AutoRst Trip; a signal will be
available when the maximum number of restarts is
reached and the VSD stays in fault condition.
• The reset input must be constantly activated.
7.1.5 Reference priority
The active speed reference signal can be programmed from
several sources and functions. The table below shows the
priority of the different functions with regards to the speed
reference.
