16.11.4 Output functions
Two special counterfunctions can be assigned to the digital outputs of the ZETADYN 4C when using
the change of direction counter:
Parameter Function Explanation
Info rope Rope-change necessary Contact closes when the actual rope still can be used, for approx
1 year.
Contact stays close until the down-counter will be reset.
TD_CNT ext. Monostable trigger circuit The output relay gives an impulse to the output at every travel
direction change.
For connecting an external counter, e.g. in the control system
16.11.5 Resetting the travel direction counter
Information
At the end of maximum change of direction ZETADYN 4C is locked and the error "E950 TD_CNT:
Drive Limit" appears in the display.
To move the cabin into the position for a cable change after locking the frequency inverter, the
ZETADYN 4C must be switched off and back on. Then a further run is possible.
After a successful cable change, the password must be entered in the Statistics menu and the down
counter set to its new start value:
Statistics
|
-
" TD_PW 0
|
-
" 0
*Password entry
Entert he current password in the menu "Statistics", "Parameter" "TD_PW" to
be able reset the value of the down counter.
Statistics
|
-
" TD_CNT 0 M
|
-
" 0
*Down counter start value
Enter the maximum allowed travel directions with the parameter "TD_CNT" in the
menu "Statistic".
After successfully setting the down counter the number of counter resets "TD_RES" is increased by
one.
To display the current value of TD_RES the key
must be pressed in the INFO menu on page 20.
16.11.6 Restore the counter reading from the absolute value encoder
The counting value of the travel direction change counter is automatically saved in the absolute value
encoder. This is performed at the following intervals:
•
up to 1,000 direction changes, performed every 100 direction changes
•
up to 10,000 direction changes, performed every 1,000 direction changes
•
above 10,000 direction changes, performed every 3,000 direction changes
The function is possible in absolute value encoders with EnDat, Codeface and Hiperface interfaces.
The current counter reading can be loaded into the ZETADYN from the absolute value encoder:
Statistics
|
-
" TD_PW 0
|
-
" 0
*Password entry
In the "Statistics" menu, enter the current password for the parameter
"TD_PW".
Statistics
|
-
" TD_RST OFF
|
-
" ON
*Restore counter reading
In the "Statistics" menu, set the parameter "TD_RST" to "ON".
The counter reading is restored and can be viewed in the parameter TD_CNT in
the Info menu on page 20.
