3.3 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
protective 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 de-
vice. If it is higher than specified, there is an error in the wiring. Switch the de-
vice 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.
The operating software supports further commissioning and diagnosis.
Afterwards the fieldbus communication can be established. For defining the
interface the relating GSDML file should be provided to the fieldbus master
Pre-parameterisation
Now set up the following parameters (with reference to the system design and
circuit diagrams):
The SYS_RANGE, SENSOR SETTING, OUTPUTSIGNAL, ACCELERATION
and DECELERATION.
Pre-parameterisation is necessary to minimize the risk of uncontrolled
movements.
Parameterize specific settings for the control element (MIN for deadzone
compensation and MAX for maximum velocity).
Reduce the speed demand to a value which is uncritical for the application.
Control signal
Check the control signal to the valve. At the current state no current should
flow to the solenoids.
Switching on the hydraulics The hydraulics can now be switched on. The module is not yet generating a
signal, means there should no (unwanted) reaction occur.
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 (with ENABLE the actual position is
accepted as the required position). If the drive moves to an end position, the
polarity is probably wrong.
Manual (HAND) operation If START is disabled, the axis can be moved manually with HAND+ or
HAND-. After disabling the HAND signal, the axis stops in a controlled
manner at the current position.
Activating
START
With the start signal the demand value of the analogue demand value input is
accepted and the axis moves to the predefined target position.
If START is disabled, the axis stops in the preset deceleration distance D:S.
Controller optimization Now optimize the control parameters according to your application and its
requirements.
