Description
Digital
outputs
3 1 to 3
1 to 3 identify digital output lines 1 to 3 of the Digital I/O socket (p. 227).
These lines can be used to trigger external devices in conjunction with axis
motion (CTO command and corresponding parameters (IDs 0x18000201 to
0x18000209)).
Digital output 4 (pin 8 of the Digital I/O socket) is not accessible for
commands. It outputs the servo cycles.
The number of digital output lines that are accessible by commands can be
queried via the Number Of Trigger Outputs parameter (ID 0x0E000B05).
Wave
generators
3 1 to 3 The number of wave generators corresponds to the number of logical axes.
Each wave generator is permanently allocated to a logical axis.
If the E-727 is configured for a 4
th
axis, a 4
th
wave generator is also present.
Wave
tables
40 1 to 40 The wave tables contain the (temporarily) saved data (a total of 262144
points) for the waveforms that are output by the wave generators.
The value of the Number Of Waves parameter (ID 0x1300010A) indicates
the number of wave tables.
DDL tables 3 1 to 3 The DDL tables contain the data of the Dynamic Digital Linearization (DDL)
feature. The number of DDL tables corresponds to the number of logical
axes. Each DDL table is permanently allocated to a logical axis.
If the E-727 is configured for a 4
th
axis, a 4
th
DDL table is also present.
The total number of points provided for the DDL tables is 262144, indicated
by the Max DDL Points parameter, ID 0x1400000B.
Data
recorder
tables
≤8 1, 2, … The data recorder tables contain the recorded data (a total of 262144
points). The number of data recorder tables can be set with the Data
Recorder Chan Number parameter (ID 0x16000300). The Max Number Of
Data Recorder Channels parameter (ID 0x16000100) indicates the
maximum number of data recorder tables.
Overall

E-727 as an overall system.
Firmware
units
2 1, 2 The number of different firmware units present in the E-727.
