Digital frequency extension module | Parameter setting & configuration

Digital frequency input

Parameter setting

Monitoring of the "Enable" or "Lamp control" signal

If the +5 V encoder voltage is not controlled by the digital frequency extension module, a

digital signal can be read in and monitored via pin 8 of the digital frequency input X9, e.g.

the "Lamp control" signal of an encoder or the "Enable" signal of an upstream digital

frequency module.

 If pin 8 of the digital frequency input X9 is not set to HIGH level (+5V) after the

initialisation time has elapsed, a fault message is generated and the response set in

C13041

/ C14041 is executed.

 The binary status of pin 8 is also displayed at the output DFIN_bSense of the system

block LS_DigitalFrequencyInput .

Track monitoring (open circuit detection)

The signal tracks A, B, and Z are monitored with regard to their differential voltage value.

 For the activation of track monitoring, two modes are available in C13014

/ C14014:

 Monitoring is both done at standstill and while the encoder is rotating.

 If track monitoring responds, a fault message is generated and the response set in

C13040

/ C14040 is executed.

– At the same time the corresponding output DFIN_bTrackAError, DFIN_bTrackBError

or DFIN_bTrackZError of the system block LS_DigitalFrequencyInput is set to TRUE.

C13014 / C14014 = "1" C13014 / C14014 = "2"

The track monitoring modes are activated after the

initialisation time has elapsed.

• The initialisation time is set in C13013

/ C14013.

The track monitoring modes only become active if pin 8

of the digital frequency input X9 is set to HIGH level

(+5 V).

• They may be activated e.g. by an encoder (status

"Lamp control") or an upstream digital frequency

module (status "Enable").

• When this mode is selected, monitoring can be

switched active by a signal source if the levels on the

tracks have valid values.
