ROTARY INDEXING TABLE CONTROLLER
EF2...B
OPERATION / DESCRIPTION OF WEISS SOFTWARE | 8.5 Operation and Monitoring
The function "Measuring cycle quick stop" is used to determine the stopping times. The measurement triggers a
movement of the rotary indexing table in the selected mode.
The result of the measurement is dependent on the mass moment of inertia of the load and the rotary indexing table.
The rotary indexing table needs to be able to rotate freely during the measuring cycle.
Automatic start
A measurement is first taken while the rotary indexing table is in standstill and afterwards a measurement is taken
with the rotating rotary indexing table in motion. Depending on the type and loading of the rotary indexing table, the
stationary measurement can take several minutes. Due to the subsequent automatic start of the rotary indexing
table for the rotating measurement, persons in the vincinity of the rotary indexing table can be in danger. The danger
area must not be accessed during the entire measurement. Serious injuries are possible due to crushing and impact.
1. Set the inputs "Enable" and "Stop (low-active)".
These two inputs have to be set in order to enable manual operation.
2. Select mode.
Measurement - only CW
Measurement - only CCW
Measurement - alternating with Start CW
Measurement - alternating with Start CCW
3. Measuring cycle Start quick stop
The stopping times are determined and displayed.
4. Confirm determined stopping times.
Confirm messages in the following windows that open up.
The determined stopping times are and displayed.
IMPORTANT for SIL 3: Adjust a delay time, which is longer than the measured stopping time, on the safety
switching device.
After the Measuring cycle quick stop has been carried out once with validity, a stopping time for the quick stop is
configured in the controller.
To check the compliance with the configured time, the modes for checking the quick stop can be used.
Checking - only CW
Checking - only CCW
Checking - alternating with Start CW
Checking - alternating with Start CCW
In this case, a movement of the rotary indexing table is carried out; the duration of which is normally shorter than the
actual measurement of the quick stop ramp. Result of the measurement: Quick stop ramp checked or Quick stop
ramp failed.
In case the quick stop ramp has failed, it needs to be redetermined by the measurement function.
5. After finishing manual operation: Release control authority.
New safety acceptance necessary
The function needs to be repeated for every change of the rotary indexing table (e.g. change of load).
A new safety acceptance is mandatory, because safety data was changed.
