Linear error
Linear error the potentiometer
The error should smaller than 2%.
1 Possible reasons for errors
0 The power supply for the coil's motor drive not switched on
0 The wiring the higher and lower commands inverted
0 The wiring the end switch information missing inverted
0 The connection the potentiometer wrong incomplete

We recommend following the below linearization procedure:
0 Adjust the P-coils manually the lower end position.3.3 Manual coils Linearization
All coil calibration does assign specific current/position value the two end switches
in Ampere. For the following steps, recommend positioning someone the regu-
lator read the actual values and set the coil the desired value for linearization.
The hysteresis only compensated the coil controlled the regulator.Page Commissioning
