5. LED DISPLAYS
LED displays are possible only if the supply voltage is present. The "Ready" relay, in this case,
must not be incorporated in the auto-hold of the power supply.
POWER ON
front panel
ON : energised - axis OK
OFF : no power on axis. Check wiring, fuses, internal
fuse : (FU 5x20) - 5 A (rating 3/10) - 10 A (gauge
10/20; 12/24 16/32; 20/40)
FLASHING : axis fault (see corresponding fault on side strip).

CAUSE
- Tacho wire cut.
- Tacho wire inverted.
- Overspeed.
- Motor wire cut.
- Motor wire inverted.
Dissipater temperature too high.
LED remains on after cooling.
RESET to switch LED off.
Inadequate ac supply voltage (Min
U)
Power voltage too high (Max U).
Energy return from load too high.
Excessive ac input voltage.
Short-circuit of motor terminals
Excessive mean motor current
CORRECTION
* Check tacho wiring
* Check axis works correctly
without tacho
(selector S3 in position 0)
* Check motor wiring
* Check ventilation
* Ambient temperature too high :
fit ventilation system
* Check supply phases are
present
* Check input voltages
* Check transformer star-delta
coupling
* Check input voltages.
* Reduce axis working speed
to reduce braking energy.
* Increase servo amplifier gain.
* Check motor wiring.
* Inadequate motor choke
(Axem motor) : add series
choke.
* Reduce servo amplifier gain.
* Reduce working cycle.
NOTE : Recovery control is also displayed (REC)
