If the "Unlisted valve" entry is selected, press the "Continue" soft key to go to the
"Unlisted Valve Data for HLA" menu display (see Fig. 3-7). If you press softkey
"Continue" 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 pro-
cess. The "Cylinder data" menu display then appears (see Fig. 3-9).
The following data appears in the MMC list display for a stored valve when you
select one:
S
Company
S
Order No.
S
Type
S
Nominal flow rate
S
Knee-point voltage
S
Nominal flow rate A:B
S
Code
If you select a valve from the list, the following machine data is preset (i.e. the
default value is overwritten):
S
MD 5106: VALVE_CODE (valve code no.)
S
MD 5107: VALVE_NOMINAL_FLOW (nominal flow rate of valve)
S
MD 5108: VALVE_NOMINAL_PRESSURE (nominal pressure drop of valve)
S
MD 5109: VALVE_NOMINAL_VOLTAGE (nominal 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
(ratio of flow rate at the A end to the B end 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)
