Master frequency input X1
This input cannot only be used for the connection of the master frequency output of
another BL 4000-C. It can also be used for the connection of encoders as per the RS422
industry standard or of encoders with "single-ended" TTL output or "open-collector"
outputs. If TTL encoders are used, it must be taken into consideration that the hysteresis
is negligible. In addition, the requirements concerning the signal shield must be fulfilled.
As an alternative, the A and B track signals of the device are interpreted as pulse direction
signals by the device so that the servo drive can also be controlled by stepper motor
control boards.
Ensure the correct configuration of the interface. This is important since the master
frequency input can also be used as the master frequency output.
