Communication
In order to provide for a perfect operation, we recommend the use of Lenze system

cables. (¶ 42)
Check the plug connections of the bus cables with regard to a tight fit.

Connection of digital frequency coupling at X10
Master frequency features:
ƒ
– Angular resolution / number of increments max. 12 bits / 1024 increments
switchable to 512 / 256 / 128 / 64 and 32 increments
– Track signals A, B, Z in accordance with RS422 standard
– Output impedance R
Output X10
l
Output frequency: 0 ... 500 kHz
l
Current capacity per channel: max 20mA.
l
Two−track with inverse 5 V signals (RS422) and zero
track
l
In case of a parallel connection maximally three
slave drives can be connected
l
By LOW level, PIN 8 (enable) indicates the
initialisation of the master drive (e. g. when the
mains has been switched off in the meantime). This
enables the slave drive to monitor the master.
