3 Manual coils Linearization
All coil calibration does assign specific current/position value the two end switches
in Ampere. Larger deviations are sign error the poten-
tiometer faulty connection.
Figure 61: Starting point for manual linearization
We recommend following the below linearization procedure:
0 Adjust the P-coils manually the lower end position. doesn’t work
if the coil adjusted externally (directly the motor drive unit). the scaling the P-coil's mechanical display not linear, the regulation has
to linearized.Page Commissioning
We take care it. 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.
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
