DIGIVEX Little Drive Servoamplifier
6. SERVO-CONTROL PARAMETER
FUNCTION AND SETTING

6.1 Servocontrol Parameter Functions

6.1.1 List of parameters

Choice of regulation type:
Speed Proportional: P
⇒ Proportional integral: PI
⇒ Proportional double integral: PI
Current regulation
In all cases
•
Filtering frequency
•
Offset
•
Current limitation
For speed regulation (P, PI, PI²)
•
Maximum speed
•
Speed for 1 V
•
Proportional gain
•
Integration stop
•
Predictors (gravity, dry or dynamic friction, acceleration).
6.1.2 Regulation selection: current, proportional, PI, PI²
Current regulation
Choosing "current" means current can be controlled directly (therefore the motor torque through
the torque coefficient Kt). This then gives 10 V = pulse peak current of the drive selected
beforehand.
2
In this mode, PI/PI
settings and predictors are neutralized. The only functions operative are:
Current limitation (often reduced below the permanent drive current, so as not to trip in mean or
rms values.
The second order low pass filter (filtering frequency), for reducing the effect of any resonance.
