Special features

The welding controller features the following specifics:
• Timer has been prepared for networking with an ProfiNet module
• Number of electrodes: 10 (electrode no.: 0 to electrode no.: 9)
• The "Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically reset
• With spot addressing ( spot selection + ident) via 24 Inputs
7.1.1

Preparation for Control System PSQ6000 XQR

Control is prepared for the control system PSQ6000 XQR.
Rewelds are done in UI-Mode, measured or controlled
(details refer to Tab1. Required and supplementary documentation, Rexroth
PSI6xxx UI regulation and monitoring).
KSR-supervision is further active, if UI-supervision without UI-regulation is
programmed.
7.1.2

Supervision of minimum current

The time within which the current has to exceed a minimum threshold is
adjustable. If this threshold is not exceeded on average, the sequence is stopped
and an error message occurs.
7.1.3

Gun life time

A gun lifetime counter is assigned to each electrode. At each welding sequence
the wear factor is added to this counter.
Via the parameters „Gun wear warning" and „Maximum gun wear" will be the
monitoring for each electrode parameterized:
• „Maximum gun wear" = 0  Welding schedules are not counted.
• If the counter reaches the value of „Gun wear warning " a status message will
be displayed and the output „Prewarning gun" will be set.
• If the counter reaches the value of „Max. gun wear", a status message will be
displayed.
The gun lifetime counter will be reset with writing of the counter to 0.
7.1.4

Gun maintenance

A gun maintenance counter is assigned to each electrode. At each welding
sequence the count factor is added to this counter.
Via the parameter „Maintenance warning" and "Maintenance interval" will be
parameterized the maintenance for each electrode:
