3. Product description
Festo P.BE-CMMD-AS-HW-EN 1002NH 29
Using software, the increment generator interface can be configured as both output and
input (master or slave). Additionally, two inputs for the connection of 5V pulse-direction
signals (CLK/DIR), (CW/CCW) are planned on the plug connector.
24V DC pulse-direction signals are carried out via [X1] DIN2 and DIN3.
Note
5 V DC Pulse-direction signals over [X10], max. 150 kHz
24 V DC Pulse-direction signals over [X1], max. 20 kHz
Output: Generation of increment generator signals [X10]
Based on the encoder data, the motor controller generates the tracking signals A/B as
well as the zero pulse of an increment generator. The number of lines can be set in the FCT
with values between 32 … 2048.
Changes to this interface only become effective after a Reset. (download, secure, reset)
An RS422 power driver provides the signals to [X10] differentially.
Input: Processing of frequency signals [X10]
The signals are evaluated optionally as A/B track signals of an increment generator or as
pulse/direction signals (CW/CCW or CLK/DIR) of a stepping motor control. The signal form
is selected in the FCT. The number of steps per revolution can be parameterized. Beyond
that, an additional electronic gear can be parameterized.
The following signals can be selected:
A/B tracking signals
CLK/DIR – pulse/direction
CW/CCW – pulse
Input: Processing of pulse-direction signals 24 V DC [X1]
CLK/DIR – pulse/direction
CW/CCW – pulse
24V DC pulse-direction signals are carried out via [X1] DIN2 and DIN3.
