EASY-DRIVER – User’s Manual
25
Please note that:
-
only cells marked in
green
are
NOT
read only
In order to make changed parameters effectively updated and in operation
it is necessary to send the MPUP command to the EASY-DRIVER module first.
(see ‘MPUP Command’ Section for more information).
Please refer to Table
4
to write values to configure correctly the EASY-DRIVER
module and note that the command to be used is:
-
‘MWG’ command to write the respective “value” cell content;
Example
: suppose that the proportional term value – K
p
– of the internal PID
digital regulator has to be changed to 0.0015. Referring to
Table 4
, this value is
accessible and it is placed at cell number 13.
The following command needs to be sent to the EASY-DRIVER unit:
MWG:13:0.0015
\r
and should receive an acknowledgment reply from the power supply – i.e.
‘#AK\r’. In order to make the module apply the value K
p
= 0.0015 to its internal
regulator it is necessary to send the MPUP
\r
command.
“Value” Section Cells
Herein, in order to correctly configure and check the power supply operation, a
brief description of the user-definable cells is presented:
-
K
P
–
cell 13
: this value is the proportional gain coefficient of the internal digital
PID regulator;
-
K
I
–
cell 14
: this value is the integral gain coefficient of the internal digital PID
regulator;
-
K
D
–
cell 15
: this value is the derivative gain coefficient of the internal digital
PID regulator;
-
Identification
–
cell 27
: this value, a string, defines the EASY-DRIVER
module identification name (and can be read with the ‘MRID\r’ command);
-
Slew Rate
–
cell 30
: this value [A/s] determines the slew-rate value of the power
supply. The module ramps, using the command ‘MRM\r’, at a defined set-point with
this pre-defined value of slew-rate.
