Recording Data In Servostudio2 - Servotronix CDHD2S User Manual

Tuning
To improve or change the performance of your CDHD2S system, please refer to the
performance diagnostic chart and manually modify and evaluate parameters.
Procedure: Modify and test parameters
After each modification of parameters, please perform the following operations:
1. Make sure the operation mode is set to serial position.
2. Perform forward and backward movements, and record PE, ICMD and PTPVCMD.
3. Use the ServoStudio2 "Range" screen to plot and evaluate the recorded values.
4. Check the PE settling time.

8.6.2 Recording data in ServoStudio2

Procedure: Recording data in ServoStudio2 - example
1. In the ServoStudio2 Range screen, select the Run tab.
Set the target position value to 3 turns.
◼
Set the values of the motion parameters to produce a motion at 50% of the motor's
◼
maximum velocity, and 75% of the maximum acceleration required by the application. In
this example:
Maximum velocity (cruise velocity) is set to 1000
⚫
Acceleration (and deceleration) is set to 50000
⚫
If forward and backward movements are required, select the "Alternate" option.
◼
The aim is to obtain motion profiles with a large duration of acceleration, smooth and
deceleration stages.
2. In the Logger Setup panel, select the following record variables:
PTPVCMD (position command velocity)
◼
ICMD (current command)
◼
PE (position error)
◼
3. In the "Logger Setup" panel, enter the sample value and trigger variable:
Sample: 1000
◼
Interval: 16
◼
Trigger: IMM
