5.5 Axis adjustment
In order to be able to set the axes, their corresponding feedback devices must be previously
connected to the CNC.
Before making this adjustment, position the axes near the middle of their travel and place the hard
stops (monitored by the electrical cabinet) near these mid-travel points in order to prevent any
possible damage to the machine.
The axis adjustment is carried out in two steps. First, the servo drive loop is adjusted and, then, the
CNC loop.
Drive loop setting
1. Verify that the power output of the drives is OFF. Set all a.m.p. FBALTIME (P12) to a value other
than "0"; for example, FBALTIME=1000.
2. Turn the CNC OFF.
3. Turn the drive power output ON.
4. Turn the CNC ON.
5. If the axis runs away, the CNC will issue the following error message for this axis. Turn the CNC
off and swap the tacho wires at the drive.
6. Repeat steps 4 and 5 until the CNC stops issuing errors.
Loop setting of the CNC.
The axes are set one at a time.
1. Select the JOG operating mode at the CNC
2. Jog the axis to be adjusted.
If the axis runs away, the CNC issues the corresponding following error message. In this case,
the a.m.p. LOOPCHG (P26) must be changed.
If the axis does not run away, but it does not move in the desired direction, Change both a.m.p.
AXISCHG (P13) and LOOPCHG (P26).
