44/132 Installation
Bosch Rexroth AG
, SYEPS series 1X, RE 30201-B/07.2014
▶
See to it that the installation position provides ease of maintenance, i.e.
unhindered access to connection lines. Ensure free access to the connection
side.
▶
Before installing the SYEPS punching system, note the details given on the
nameplate. If nameplates are no longer visible or legible after installation you will
have the data at hand at any time.
Further information can be found in operating instructions 30139-B.
7.5.4.1 Place of installation of HNC100, valve amplifiers and amplifier modules
The HNC100, valve amplifiers and amplifier modules should not be installed next to
power electronics (e. g. frequency converters, etc.). The power supply unit of the
HNC100 should be installed as close to the HNC100 as possible.
7.5.4.2 Voltage supply
▶
Keep the connection as short as possible and install supply and return
conductors (+24 V/GND) together. Voltage 18-30 V with a residual ripple of
<1.5 Vpp, I = 1 A.
▶
Install power cables consisting of two individual wires (voltage supply) in parallel
or as twisted cable.
For the total current requirement, see the data sheet for the punching axis SYEHL,
30200.
7.5.4.3 Shielding
For signal cables, use only cables with a copper braid shield. Connect the cable
shield on one side on a large area to the metallized plug-in connector housing and on
the HNC100 side. This is achieved by pushing the shield back and clamping the cable
under the strain relief.
7.5.4.4 Suppressing interference of the system
Should interference occur in conjunction with signals of the HNC100, inspect the
interference suppression of other electrical components, e. g. as follows:
Switched inductance:
DC: anti-parallel free-wheeling diode across actuator
winding
AC: type-related R/C combination across actuator
winding
Electric motors:
R/C combinations from each motor winding to ground.
Frequency converter:
Input filter in the voltage supply of the frequency
converter.
Motor control lines shielded and installed separately
from other cables and/or output filter for motor cables.
Extensive contact of the frequency converter housing to
the rear wall of the control cabinet
