Elife UNIDRIVE M series, Reference Manual

Page: 48 / 84

Note
The CANopen
®
values will only processed if UNIDRIVE works in CAN
Network or PLC configuration.
3.4.5 Locked Parameters
In Programmable Parameters tab there are a few programmable parameters which
their text-boxes are disabled but filled with a value (Figure 3.4). You can unlock
them and change their value.
Warning
These parameters are critical for the correct function of UNIDRIVE. You should
change these parameters carefully and only if necessary.
In order to change these parameters:
1.
Click on Change Locked Parameters button.
2.
Insert the password: 8192
After unlocking, you will be able to change:
Current Loop Kp
Proportional gain for closed-loop current control; it must be less
than 1024. This parameter is also programmable by CANopen
®
protocol.
Current loop Ki
Integral gain for closed-loop current control; it must be less than
512. This parameter is also programmable by CANopen
®
protocol.
Tips and Advice
The Kp and Ki values can be calculated by using Telemetry Panel. See
Section 3.5.1

It indicates the number of motor poles and must be taken from motor
datasheet.
