4.8 Adjustment of position controller (Fig. 13)
The built-in position controller REGADA is a user-friendly control system to control actuators with an
analogue signal. The controller takes advantages of high-power RISC processor MICROCHIP to perform all
functions. It provides also continuous automotive diagnostics of the system, error messages as well as number
of relay switching and number of controller's operation hours. Placing an analogue signal onto the input terminals
of the terminal board 86 (GND, -) and 88 (+) causes that the EA output is reset.
Required parameters and functions can be programmed using function buttons SW1 - SW2 and LED
diodes D3 - D4 placed directly on the controller, see Table 4 .
4.8.1 Setting of controller
The controller's microprocessor unit is in the production plant programmed to parameters given in Table 4
(Note 2).
Setting of the controller is performed using buttons and LED diodes.
Adjust the position and torque switches and the position transmitter before adjustment of the controller.
In addition, it is necessary to monitor the correct running of the electric motor concerning the sequence number
of phases, otherwise it may happen that during automatic calibration, the engine will run in the opposite direction
and the controller will not detect this as an error.
Laying of adjusters and signaling elements on the board of the REGADA controller is shown on Fig. 13 :

Notes:
1. The controller at autocalibration automatically sets the feedback type - resistant/current
2. (*) Parameters set in the production plant, if customer has not stated else.
