3.4 Commissioning
Step Task
Installation Install the device in accordance with the circuit diagram. Ensure it is wired cor-
rectly and that the signals are well shielded. The device must be installed in a pro-
tective housing (control cabinet or similar).
Switching on for the first time Ensure that no unwanted movement is possible in the drive (e. g. switch off the
hydraulics). Connect an ammeter and check the current consumed by the device.
If it is higher than specified, there is an error in the wiring. Switch the device off
immediately and check the wiring.
Setting up communication Once the power input is correct, the PC (notebook) should be connected to the
serial interface. Please see the WPC-300 program documentation for how to set
up communication.
Further commissioning and diagnosis are supported by the operating software.
Pre-parameterization Now set up the following parameters (with reference to the system design and cir-
cuit diagrams):
The SYS_RANGE, SENSOR SETTING, OUTPUT SIGNAL, PRESET:Q, RAMPs.
Pre-parameterization are necessary to minimize the risk of uncontrolled move-
ments.
Parameterize specific settings for the control element.
Reduce PRESET:Q and p to a value which is uncritical for the application.
Control signal Check the control signal with voltmeter (ammeter). The control signal lies in the
range of ± 10 V
(4…20 mA). In the current state it should be 0. Alternatively, if
current signals are used, approx. 0 mA should flow.
Switching on the hydraulics The hydraulics can now be switched on. Since the module is not yet generating a
signal, the drive should be at a standstill or drift slightly (leave its position at a
slow speed).
Activating ENABLE CAUTION! The drive can now leave its position and move to an end position at
full speed. Take safety measures to prevent personal injury and damage.
The drive stays in the current position. If the drive moves to an end position, the
polarity is probably wrong.
Activating START With the start signal (RUN), the controller is activated. On the intended pressure
point is the Assembly control the pressure according to the setpoint.
Optimize controller Now optimize the control parameters according to your application and your re-
quirements.
