3.3.12 Incremental encoder interface [X10]
Using software, the incremental encoder 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 incremental encoder – [X10] is output:
From the rotational angle determined via the encoder at the motor, the controller gener-
ates the tracking signals A, B as well as the zero pulse of an incremental encoder. The sig-
nals A, B, and N equal those of an incremental encoder.
Angle resolution / Number of lines Output
The number of lines is continuously switchable. The following numbers of lines are sup-
ported: 2048 - 32 lines per revolution. The switchover only becomes effective after a RESET
of the controller. An RS422 line driver provides the signals to X10 differentially.
Synchronization – [X10] is input:
Using software, the X10 interface can be configured as an input for processing of incre-
mental encoder or pulse-direction signals.
The signals are evaluated optionally as A / B tracking signals of an incremental encoder or
as pulse / direction signals (CW/CCW or CLK/DIR) of a stepping motor control. The signal
form is selected via software. The number of steps per revolution can be parameterized.
Beyond that, an additional electronic gear can be parameterized.
3.3.13 Serial parameterization interface RS232 and RS485 – X5
It permits parameterization of the controller as well as downloading of the parameter set
and firmware through an RS232 zero modem interface with up to 115 KBit/s.
The interface can be used either as an RS232 interface or alternatively as an RS 485 inter-
face. Simultaneous use is not possible, since both interfaces use the same UART in the
DSP.
3.3.14 SD cardholder X12
To permit saving of control parameters as well as the complete controller firmware, a con-
nection 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.
3.3.15 SD memory card
Via the SD memory card, parameter records can be loaded or firmware can be downloaded.
A menu in the configuration software allows you to specify a set of parameters on the
memory card, and load it or save it.
