SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
If you select entry "Unlisted valve", choose softkey "Continue" to go to menu
display "Unlisted valve data for HLA" (see Fig. 3-7). If you press softkey "Con-
tinue" otherwise, the machine data assigned to the entry are written to a buffer
whose contents are transferred to the drive at the end of the start-up process.
You can then go to menu display "Cylinder data" (see Fig. 3-9).
The following data are output in the MMC list display for a stored valve when
one is selected:
S
Make
S
Order No.
S
Name
S
Rated flow rate
S
Knee-point voltage
S
Rated flow rate A:B
S
Code
If you select a valve from the list, the following machine data are preset (i.e. their
default setting is overwritten):
S
MD 5106: VALVE_CODE (valve code no.)
S
MD 5107: VALVE_NOMINAL_FLOW (rated flow rate of valve)
S
MD 5108: VALVE_NOMINAL_PRESSURE (rated pressure drop of valve)
S
MD 5109: VALVE_NOMINAL_VOLTAGE (rated valve voltage)
S
MD 5110: VALVE_DUAL_GAIN_FLOW (knee-point flow rate of valve)
S
MD 5111: VALVE_DUAL_GAIN_VOLTAGE (knee-point voltage of valve)
S
MD 5112: VALVE_FLOW_FACTOR_A_B
(rated flow rate ratio between A and B ends of valve)
S
MD 5113: VALVE_CONFIGURATION (valve configuration)
S
MD 5114: VALVE_NATURAL_FREQUENCY (natural frequency of valve in
small-signal range)
S
MD 5115: VALVE_DAMPING (valve damping)
