Basic operation
The following describes the basic operation.
1.
After the drive contact is turned on, pulse output is started and the speed is increased from the bias speed.
2.
After the speed has reached the specified speed, the operation will be performed in the specified speed.
3.
If the command speed is changed during operation, the speed is increased/decreased to the specified speed and
operation continues.
4.
If the drive contact is turned off, the speed is decreased and pulse output is stopped.
Operand specification
■When FX5 operand is specified
1.
For (s), specify the command speed. Set to a value -200 Kpps to +200 Kpps in pulse.
• PLSV: -32768 to +32767 (User system unit)
• DPLSV: -2147483648 to +2147483647 (User system unit)
2.
For (d1), specify an axis number (K1 to K12) for which pulses are output.
Specify an axis number whose positioning parameters are set in the high speed I/O parameters. Operation cannot be
performed if any other axis number is specified.
• K1 to K4: Axis 1 to Axis 4 (CPU module)
• K5, K6: Axis 5, Axis 6 (High-speed pulse input/output module first module)
• K7, K8: Axis 7, Axis 8 (High-speed pulse input/output module second module)
• K9, K10: Axis 9, Axis 10 (High-speed pulse input/output module third module)
• K11, K12: Axis 11, Axis 12 (High-speed pulse input/output module fourth module)
