CcwIgnore Counter clock wise ignore: Ignores the Ccw switch
This signal ignores the position of the Ccw switch of the nutrunner. The program selected is always
started.
CwIgnore Clock wise ignore: Ignores the Cw switch
This signal ignores the position of the Cw switch of the nutrunner. Program no. 99 is always started.
CcwLock Counter clock wise lock: Disables the loosening function
This signal disables the tightening program no. 99 (Loosen) in a tightening channel.
Cw Clock wise: Starts tightening in clockwise direction
A selected tightening program is started with the
Cw
start signal. The start signal remains set to "high"
during the entire execution, until OK/NOK evaluation. If the
Cw
start signal changes to "low" during
tightening, the tightening program will be canceled with NOK and the quality evaluation "Canceled by
PLC". After an OK/NOK evaluation has been made, the signal can be set to "low" without any effect on
tightening.
If an attempt is made to start a faulty tightening program, the tightening program is exited immediately with
an NOK evaluation. If an attempt is made to start a non-existent tightening program, the display shows a
message stating that there is no tightening program. There is no evaluation.
If the
Play at start
function is active, a tightening start is not considered performed if the maximum
occurring torque remained below the defined torque threshold 1) . The controller then does not performs
any evaluation (OK/NOK) and results output.
CwLock Clock wise lock: Disables the starting function
This signal serves to lock the start of the selected tightening program.
CntRes Counter Reset: Resets the counter value
When this signal is set to "high", both counters of the OK/NOK counter are reset to their programmed
initial state. Simultaneously, the channel is enabled, i. e. any nutrunners locked by the OK/NOK counter
will be released.
CntSel0-7 Counter Select Bit 0-7: Selects the counter value
These signals are used to select the OK/NOK counters. This selection takes effect irrespective of the
tightening program, e.g. by the partner controller. If a new counter value is selected before the default
value for the OK/NOK counter is reached, the channel is disabled (optional) and evaluated with
CntCanceled
= "high".
DisRp Disable Report: Suppresses the results output
When the
DisRp
signal is "high", the results output (e.g. printer output) can be suppressed for the
subsequent tightening program. Outputs within the scope of the operating system are not suppressed.
DisRpFtp Disable Report Ftp: Suppresses the results output via FTP
The FTP results output can also be suppressed by the PLC using the
DisRpFtp
PLC signal (signal
DisRpFtp
= "high"). This avoids having to wait for the results output when restarting. This function is
particularly useful when several tightening programs are started in a row.
No zero point test is implemented when program no. 99 is started with the signal
Ccw
.
1 This threshold can be set in the start step of the tightening program; the default value is 5% of the
nominal torque of the nutrunner.
