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).
