Encoder emulation

The output [X11] of the motor controller can simulate an encoder that can be used by another device as
an input signal.
The output [X11] is active even if the function has not been activated in the FCT.
In the FCT, the following configurations can be made.
Option
Encoder Data
Number of lines
Offset Angle
Options
Disable track A,B
Suppress zero pulse
Inverse rotation polarity
Encoder output
Position virtual master
Actual position
Setpoint value position
Tab. 6.22 Configuration of the encoder emulation
Festo – GDCP-CMMP-M0-FW-EN – 1304NH
Description
Number or lines (increments) per revolution.
Track A and track B are offset by 90°. As a result, the connected
incremental input can increase the resolution with a fourfold
evaluation. The result is, the number of increments per revolution is
increased by the factor 4.
Additive correction value in the range from -180° to +180° for
electronic adjustment of the zero position.
The incremental signals are not output ("encoders standing still").
The emulated incremental encoder does not output a zero pulse.
The phase position of tracks A and B is rotated by 180° (right rotation
field -> left rotation field)
Only for activated cam disc function with virtual master.
– With cam disc function: actual value of slave position.
– Without cam disc function: actual position of the motor controller.
– With cam disc function: setpoint position of the slave.
– Without cam disc function: setpoint position of the motor
controller.
