(LU= Length Unit = the length unit based on the actual value weighting
factor (AVWF))
♦ Velocities of virtual master
1000 [inc/sec]
↔ 6000 [10 LU/min]
=> all parameters previously set have to be multiplied by 6; the
value output or indicated in the monitoring parameters and
connectors is greater by a factor of 6.
This affects the following parameters and connectors:
• U682
• U679/KK818 or the connector connected via U680
• Monitoring parameters n691 and n692
• Connector KK816
♦ Acceleration of virtual master
1000 [inc/sec
2
] ↔ 1 [1000 LU/sec
2
]
=> the parameter previously set (U685) should be divided by 1000
♦ Normalization of slave velocity setpoint (
↔ speed/velocity
precontrol)
1000 [inc/sec]
↔ 60 [1000 LU/min]
=> the parameter previously set should be multiplied by 0.06.
Machine data 49 is defined in 1000 LU/min, unlike the velocity setpoints
and actual values.
A series of enhancements has been made that does not affect the
compatibility with older software versions:
♦ The velocity override can now be defined by any connector selected
in U709.
♦ A series of new display parameters has been introduced (e.g. n540,
n541, n542).
♦ The positioning status bits are now connected to individual binectors
(B351...B562 [811.3])
