2 Safety Safety In this Chapter Intended Use ..........................5 General Safety Instructions......................5 Organizational Measures ....................... 6 Intended Use The E-625 is a laboratory device according to DIN EN 61010. It is intended to be used in interior spaces and in an environment which is free of dirt, oil and lubricants. Corresponding to its design, the E-625 is intended for driving capacitive loads (e.
2 Safety Use the supplied components (power supply, adapter, power cord) to connect the E-625 to the power source. If one of the supplied components for connecting to the power source has to be replaced, use a sufficiently dimensioned component. If a protective earth conductor is not or not properly connected, dangerous touch voltages can occur on the E-625 in the case of malfunction or failure of the system.
Features and Applications The E-625 piezo servo controller is a benchtop device that provides closed-loop and open-loop control of the displacement of the positioner. The models E-625.CR and E-625.C0 work with capacitive sensors that measure the position directly and without contact.

7 Operation Operation In this Chapter General Notes on Operation ......................31 Operating Modes ......................... 32 Selecting the Operating Mode ..................... 33 General Notes on Operation DANGER Risk of electric shock if the protective earth conductor is not connected! If a protective earth conductor is not or not properly connected, dangerous touch voltages can occur on the E-625 in the case of malfunction or failure of the system.
Operating Modes 7.2.1 Control Mode The E-625.CR and the E-625.C0 can be run in analog mode. Alternatively, the E-625.CR can be run in computer-controlled mode. The active control mode determines the applicable control sources for the output voltage. Analog Mode The piezo voltage depends on the input voltage applied to the ANALOG IN/WTT SMB socket.
7 Operation 7.2.2 Servo Mode The servo mode determines whether the motion is performed in open-loop operation (servo mode OFF) or in closed-loop operation (servo mode ON). The control and servo modes can be combined at will. Closed-Loop Operation Control input signals (input signal on ANALOG IN/WTT or E-816 inputs over commands and wave table output) are interpreted as the target position.
In the default position, the E-802 servo controller submodule is active and the servo mode can be set as follows: Settings of the DIP switch block (E-625.CR and E-625.C0) Move the DIP switch 3 on the front panel of the E-625 to the corresponding position:...

8 Adjustment of Internal Settings NOTICE Loss of system settings when internal components are adjusted! When the system settings are changed, the original settings will be lost. Unfavorable settings can lead to oscillation of the positioner, deteriorated settling behavior and reduced positioning accuracy.
Adjustment Elements Inside the Housing The following figure shows the position of the components and adjustment elements (jumpers, switches) on the main board of the E-625.CR and on the E-802.55 servo controller submodule. The servo controller submodule is inserted vertically on the main board.
The servo mode can be controlled with switch 3 on the Settings DIP switch block and (only for E-625.CR) over the E-816 computer interface submodule. The slew rate limiter for the piezo voltage and the notch filter remain active even when servo mode is switched off.

8 Adjustment of Internal Settings Jumper X8 The X8 jumper is located on the main board (p. 37). Position Function DC-offset potentiometer is activated. Only activate when a DC-offset potentiometer (not included in the scope of delivery) is connected. DC-offset potentiometer is deactivated. Jumper JP101 to JP106 The jumpers JP101 to JP106 are used to adjust the sensor range.
8 Adjustment of Internal Settings Figure 8: Settings for the sensor evaluation range 8.3.2 Switches Switches of the E-802.55 Servo Controller Submodule The mini DIP switches and the S1 switch for the notch filter setting of the E-802.55 servo controller submodule are described in the E-802 servo controller submodule user manual. Master/Slave Switch for the Sensor Synchronization In systems with several capacitive sensors, the master/slave switch makes the master/slave settings.
The master/slave switch is located on the printed circuit board which is soldered (p. 40) vertically on the main board. Furthermore, for all E-625.CR to be synchronized, wires 7 and 8 as well as a ground wire (1, 2, or 5) of the Network socket must be connected to the corresponding wire.

8 Adjustment of Internal Settings INFORMATION If a E-625.CR is to be interlinked with at least one E-665.CR piezo servo controller for capacitive sensors: 1. Configure the E-625.CR as sensor master. 2. Configure all E-665.CR as sensor slaves (see E-665 user manual).
8 Adjustment of Internal Settings Adjusting Notch Filter and P-I Controller The E-625 is equipped with a notch filter with which the oscillations at the mechanical resonant frequency can be suppressed in dynamic operation. Adjusting the P-I controller optimizes the system's dynamic properties (overshoot and settling time).

Turn the P4 potentiometer on the E-802.55 servo controller submodule by using the trimmer adjustment tool to optimally adapt the notch filter frequency to the resonant frequency of the positioner. 11. Repeat the last steps until the resonant frequency of the positioner has the best damping.

In the other control modes, you must expect a deviation of 1 %. With E-625 models that can be operated computer-controlled (E-625.CR), PI does the calibration in the computer-controlled mode by default.
