9300 Servo PLC EN 5.0
Digital frequency output X10
Technical data
Connection:
Sub−D female connector, 9−pole
Output frequency:
0 − 500 kHz
Ampacity:
Max. 20 mA per channel
Load capacity:
·
With a parallel connection, a maximum of 3 slave drives can be connected.
·
With a series connection, any number of slave drives can be connected.
Properties
·
Two−track with inverse 5 V signals and zero track
·
When PIN 8 (EN) is LOW, the master drive is being initialised (e.g. if the mains was disconnected in the meantime).
The slave drive can thus monitor the master.

Note!
The digital frequency output X10 has a system−dependent delay time T
d
which can be calculated
using the following formula:
T
d
= Task cycle time (process image cycle) − 1 ms
Example: If DFOUT_nOut_v is written to in a "10−ms task", the signal at X10 has a delay time T
d
of
9 ms (10 ms − 1 ms).
