15540 Velocity control voltage conversion factor of Z–axis tracing control
15541 Velocity control voltage conversion factor of W–axis tracing control
[Data type] Word
[Unit of data]
[Valid data range] 0 to 32767
Use the following expression to calculate the conversion factor to be
specified:
Conversionfactor + G
P 4
1000 Le
2 10
*3
4096
G : Tracing control loop gain (second
–1
)
Le : Amount of machine movement per motor revolution (mm/rev)
P : Number of pulses detected by the pulse coder per motor revolution
(P/rev) (2048 for the serial A or α motor)
15544 Permissible approach acceleration
[Data type] Word
[Unit of data] mm/min
[Valid data range] 0 to 32767
A limit may be imposed on the tracing acceleration (speed increase per 2
msec) to prevent a servo overcurrent alarm from being raised at the start of
tracing. Specify this permissible value.
15545 Displacement amount at which an acceleration limit is imposed during approach
[Data type] Word
[Unit of data] 0.001 mm
[Valid data range] –32768 to 32767
A limit is imposed on the acceleration if the absolute value of the
displacement amount is larger than this setting during tracing approach.
