The voltage of the buffer battery has dropped
below the minimum value.
Exchange the buffer battery.
See ”Buffer battery” on page 18 – 257.
Ref mark <axis>:
incorrect spacing
During a reference run on an encoder with
distance-coded reference marks a distance of
more than 1000 grating periods was covered
without passing over a reference mark.
Correct the machine parameter MP1350.
See ”Encoder interface” on page 19 – 277.
Traverse
reference points
In a part program block you attempted to move
an axis that has not yet traversed the reference
point.
Move the axis over the reference point.
See ”Reference run” on page 20 – 323.
Relay: n.c. contact
open?
In the relay chain, the normally closed contact
of one or more relays is open.
Check the relay for proper function.
See ”Checking the enables on the iTNC 530

The position deviation at standstill is greater
than the value entered in machine parameter
MP1110.x.
Inform your service agency.
Analog axes: Excessive drift
Vertical axes: Poor brake or defective weight
balance
Clamped axes: Great mechanical effects during
machining
Analog axes: Adjust the drift.
Vertical axes: Check the brake or the weight
balance.
Clamped axes: Remove any great mechanical
effects during machining.
See ”Sequence for finding errors in the control
loop” on page 6 – 58.
Carry out offset adjustment. (See ”Adjusting
the electrica
l offset (drift adjustment)” on page
21 – 355.)
