Terminal assignment X9
2 Digital frequency input
The optionally available digital frequency extension module serves to extend the L-force
9400 Servo Drive by a digital frequency input and a digital frequency output.
 The digital frequency input X9 reads encoder signals with TTL level (0 ... 500 kHz) and
converts these to scaled speed and position values for the application.

If an encoder is connected to X9 and supplied by the digital frequency extension
module "in a controlled way", the pin 8 of the digital frequency input X9 serves
to control and monitor the +5 V encoder voltage. Monitoring
In this case, no digital signal ("Lamp control" or "Enable") may be supplied to PIN
8!
Please also observe the documentation for the encoder used.
