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 hy-
draulics). 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 im-
mediately and check the wiring.
Setting up communication Once the power input is correct the PC (notebook) should be connected to the se-
rial 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-parameterisation Now set up the following parameters (with reference to the system design and cir-
cuit diagrams):
SYSRANGE, SENSOR SETTINGS, POLARITY, ACCELERATION and
DECELERATION.
Pre-parameterisation is necessary to minimise the risk of uncontrolled move-
ments.
Parameterise specific settings for the control element (MIN for following error
compensation and MAX for maximum velocity).
Reduce the speed limitation to a value which is uncritical for the application.
Control signals Check the control signal with a voltmeter. The control signals (PIN 15 to PIN16
and PIN19 to PIN20) lies in the range of ± 10V. In the current state it should show
0V. Alternatively, if current signals are used, approx. 0 mA should flow.
CAUTION! This signal depends on the EOUT setting.
Profibus communication
Activate the profibus communication and check whether the right values and bits
are send to the module.
Switching on the
hydraulics
The hydraulics can now be switched on. The module is not yet generating a
signal. Drives should be at a standstill or drift slightly (leave its position at a slow
speed).
Activating ENABLE
CAUTION! Drives can now leave their position and move to an end position at full
speed. Take safety measures to prevent personal injury and damage.
Drives stay 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.
Activating START
With the start signal the demand value on the analogue demand value input is ac-
cepted and the axis moves to the predefined target position.
If START is disabled the axis stops in the preset deceleration distance D:S.
Manual (HAND) operation
If START is disabled the axis can be moved manually with HAND+ or HAND- . Af-
ter disabling the HAND signal, the axis stops in a controlled manner at the current
position.
Optimize controller Now optimize the controller parameters according to your application and your re-
quirements.
