3.5.12 Increment generator interface [X10]
Using software, the increment generator interface can be configured both as input and as
output. Additionally, two inputs for the connection of 5V pulse-direction signals (CLK/DIR,
CW/CCW) are planned on the plug connector.
Encoder emulation of the increment generator – [X10] is output:
From the rotational angle determined via the encoder at the motor, the controller
generates the track signals A and B as well as the zero pulse of an increment generator.
The signals A, B, and N equal those of an increment generator.
Angle resolution / Number of lines Output
The number of lines is continuously switchable.
The following numbers of lines are supported: 2048 – 32 lines per revolution.
The switch only becomes effective after a Reset of the controller. An RS422 power driver
provides the signals to [X10] differentially.
Synchronisation – [X10] is input
Using software, the [X10] interface can be configured as an input for processing of
incremental encoder or pulse-direction signals.
The signals are evaluated optionally as A/B track signals of an increment generator or as
pulse/direction signals (CW/CCW, CLK/DIR) of a stepping motor control. The signal form is
selected via software. The number of steps per revolution can be parametrised. Beyond
that, an additional electronic gear can be parameterized.
3.5.13 SD card holder [M1]
To permit saving of control parameters as well as the complete controller firmware,
a connection possibility for an SD memory card (popular storage medium for digital
cameras) has been incorporated. The connection has been designed as a "push-push"
holder for reasons of quality perception.
3.5.14 SD memory card
Via the SD memory card, parameter sets can be loaded or firmware can be downloaded.
A menu in the parametrisation software allows you to specify a set of parameters on the
memory card and load it or save it.
Note
When a parameter set is loaded from the memory card, the newest
parameter set is always loaded.
Also, a configuration word in the parameter record can be used to specify whether
firmware and/or a parameter record is to be loaded from the memory card automatically
on activation.
