Special features

The welding controller features the following specifics:
• Timer has been prepared for networking with an ProfiNet module
• Number of electrodes: 32 (electrode no.: 0 to electrode no.: 31)
• The "Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically reset
• Due to timer-internal routines, the minimal preweld/squeeze time is 16 ms.
• The function Initial dressing can be activated via timer parameter.
When this function is activated for a specific electrode a „Tip Dress Request"
will come immediately after the „Tip replaced" input signal.
• With activated function Initial dressing the first dress cycle will be not counted.
• When calling up welding programs with electrode nos. 1 through 9, output KSR
selection 1 is simultaneously activated. When calling up welding programs with
electrode nos. 10 through 19, output KSR selection 2 is simultaneously
activated. When calling up welding programs with electrode nos. 20 through 29,
output KSR selection 3 is simultaneously activated. For all other electrode
numbers, the KSR selection outputs are not changed.
• The pressure control valve may be optionally checked at the end of the
squeeze time.
• The „Operate force sensor" serial input status is retransmitted to the analog
output „Operate force sensor" (X9.1, 0 = 0V, 1 = 10V).
• These discrete inputs are retransmitted to serial outputs:
I17 →
o
I18 →
o
I22 →

I23 →

• This serial input is retransmitted to a discrete output:
I2.00(16) →

Preparation for Control System PSQ6000 XQR

Control is prepared for the control system PSQ6000 XQR.
Rewelds are not done in UIR-mode, but in KSR- or PHA-mode (regarding
measuring, regulation, supervision and stepper). KSR-supervision is further
active, if UI-supervision without UI-regulation is programmed.
7.1.2

Schedule

Program start is subdivided into two parts: New spot selection and Program start.
Both parts use a handshake.
New spot selection:
The robot initially selects a new spot number at the corresponding timer inputs.
Afterwards, it sets the "New spot selection" input.
