RE 30201-B/07.2014, SYEPS series 1X,
Bosch Rexroth AG
In this operating mode it must be possible to extend and retract the punching
axis without any difficulties, otherwise, the position measuring system or the high-
response valve are improperly wired, which must be corrected.
On variant
“Advanced“ the yellow LED lettered “LVDT“ indicates the wiring condition. When
the position measuring systems of the pilot and the main valve are connected, it
is off (normal condition´).
If at least one position measuring system is not connected or a cable break is
present, it illuminates yellow.
8.1.11 Checking the position control
▶
Select operating mode 32 on the HNC100 by means of R parameter R454 “new
mode“ and check, whether the axis is in the PTE position (typically 38.000 mm)
in closed-loop control.
▶
Then, check with the help of the diagnosis window in WIN-PED®, whether, in the
case of High and Advanced, the position command and actual position value are
identical and the following error(k), A variable A004, is < ±0.1. For the standard
variant, the control error is within the limits of ±0.3 mm.
If it is not, check the wiring of the valve. The power supply is missing or the polarity
of the valve command value signal is reversed.
8.1.12 Flushing the hydraulic system
To ensure a long service life and low wear, the hydraulic system must be flushed until
the following oil cleanliness is achieved:
According to old standard: NAS 1638, cleanliness class
≤
5
According to new standard: ISO 4406, cleanliness class
≤
16/14/11
According to old standard: NAS 1638, cleanliness class
≤
7
According to new standard: ISO 4406, cleanliness class
≤
18/16/13
If these values are not adhered to, the Bosch Rexroth warranty becomes void.
To minimize the flushing time, use an oil cleanliness measuring device (particle
counter) which is suitable for determining the oil cleanliness online. This instrument
can be connected to the MP test port and serves for continuous monitoring of the oil
cleanliness in the system. The instrument must be regularly inspected and calibrated
to ensure correct monitoring of the oil cleanliness.
If you have no oil cleanliness measuring device at hand, the flushing time must be
calculated according to the following formula
t
≈ x 2.5 to 5
V
q
V
Where:
t
= flushing time in hours
V
= tank capacity in liters
q
V
= pump displacement in l/min
This results in the following flushing times for typical SYEPS power units:
High and Advanced
Standard
