ROTARY INDEXING TABLE CONTROLLER
EF2...B
FUNCTION AND SIGNAL DESCRIPTIONS |
4.1 Signal description of the software inputs
Ignore
parameter set 3
Bit 8
Parameter set 3 is used for starting from an intermediate position.
Only if the position cam of the rotary indexing table has not been activa-
ted and a start is executed.
This parameter set is permanently programmed and cannot be changed.
If this parameter set is ignored, depending on the signals Parameter set 1
or Parameter set 2, the intermediate position will not be approached
slowly.
It is recommended to start with a slow start ramp (>100ms) and a low fre-
quency (f < 30Hz) in order to be gentle on the mechanics of the indexer.
Open brake
Bit 9
If emergency stop is selected and the "Open brake" signal is HIGH, the
connected brake is released.
Reset error
Bit 10
On a rising edge (> 30 ms) all existing error messages are acknowled-
ged.
Receive
watchdog
Bit 31
The watchdog mechanism serves to monitor the life sign of the EF2 by
the superordinate controller.
A signal can be specified by the superordinate controller via "Receive
watchdog". This signal is copied in the EF2 onto the "Send watchdog"
signal and sent back to the superordinate controller.
This signal can be monitored by the superordinate controller. A flashing
cycle or a static HIGH signal can be used for example as a monitoring
signal.
Jog CW
Not allocated
As long as this signal is HIGH, the rotary indexing table will rotate CW
with Parameter set 3.
Jog CCW
Not allocated
As long as this signal is HIGH, the rotary indexing table will rotate CCW
with Parameter set 3.
Special mode
Not allocated
Before starting the movement, the special mode needs to be selected by
this signal.
When starting with the signal "Cycle CW level" or the signal "Cycle CCW
level", the table will start to move - and movement will continue - as long
as this signal is HIGH.
If the table reaches the position cam, the setting is switched to Parameter
set 2 and the table will continue to move without stopping.
When the position cam is left again, the setting will return to Parameter
set 1.
If Parameter set 2 is selected, the rotary indexing table runs continuously
with Parameter set 2.
If the signal "Special mode" goes to LOW, then the current cycle will be
completed.
Afterwards, the "Cycle CW level" signal or otherwise the "Cycle CCW
level" signal can be cancelled.
By setting the frequency of Parameter set 2, the standstill time of the
rotary indexing table can be varied within certain limits.
