Functional Description .
56 | ECW500
This parameter defines if the calculated gains will be for a controller PI or PID.
If the Autotuning is going to be started for MTVC mode, this parameter must be adjusted in the PID option. For
the other operation modes (MECC, MRPC and MPFC) this parameter must be kept in the PI option.
<31108> Copy gains of Autotuning to current mode (CopyGains)
This option allows copying the value of parameters 31078, 31080 and 31082 over the gains of current operation
mode.
Example:
If the autotuning was executed with success in MTVC mode, when using the option
CopyGains the calculated
values for the control gains will be copied to gains of MTVC mode as follow:
•
ATune Kp (31078)

MTVC Kp (30016);
•
ATune Ki (31080)

MTVC Ki (30018);
•
ATune Kd (31082)

MTVC Kd (30020).
In this case, the values of the gains for other operation modes (MECC, MRPC and MPFC) remain unchanged.
NOTE!
The copy of parameters 31078, 31080 and 31082 using
CopyGain option does not affect the
gains of other mode different from the current mode.
NOTE!
If the values of parameters 31078, 31080 and 31082 are null (0.0) the function
CopyGains
have effect in the gains of current operation mode.
<31100> Higher Limit of feedback during the Autotuning (Max.Fdbck)
<31112>
Lower Limit of feedback during the Autotuning (Min.Fdbck)
These parameters define the higher and lower limits that the feedback signal can achieve for the Autotuning
don't be interrupted.
This is an additional protection during the execution of Autotuning that must to be adjusted with the values
considered safe to the operation.
Example:
If the voltage feedback in MTVC mode is 13800 V at the beginning of the Autotuning process, a Higher Limit
and a Lower Limit adjusted in 10% define that the execution of the function will be interrupted if the machine
voltage achieve a value higher than 15180 V (13800 V * 1.1) or lower than 12420 V (13800 V * 0.9).
6.11.2 Commands
To start the automatic tuning process, the autotuning command on Autotuning menu must be changed
On .
The Autotuning command can be also executed through the F2 key, since the HMI navigation screen be on the
Autotuning menu.
