Master frequency features:
– 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

Technical data master frequency
Output X10
Input 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.
l
Input frequency:
– 0 ... 500 kHz for TTL level
l
Max. 5 mA
l
Two−track with inverse signals and zero track
– With regard to incremental encoders with HTL
level, also operable without reversed signals
