TROUBLESHOOTING
Monitor Status Cause
- Amplifier disabled no fault
8 Amplifier enabled no fault
1. Overvoltage
amplifier DC bus voltage Missing, damaged or wrong designed
regeneration resistor.
2. Integrated Power Module (IPM) Trip The unit’s power base has been
overloaded
3. Overcurrent
2x Peak Current Crest Value Power stage fault or motor leads short
circiut
4. Undervoltage;
DC bus voltage has dropped below the
powerbase undervolts level
5. Feedback fault Parting of the cable or resolver leads
short circuit or missing plug-in
connection
6. Electronic Fusing (see Fault 7 also) Amplifier or motor active current
overload.
Fault detection via software.
7 1) I²t-Limit Controller/Motor
If I²t-limit is reached, amplifier will
reduce output current to it´s nominal
value. After 2.4s ± 0.5s drive switches
off (amplifier disable) with fault
indication "6; electronic fusing"
2) Motor overtemperature
3)Amplifier overtemperature 1) Cycle time between motor
acceleration and deceleration is too
short. (Duty cycle too high)
2) Missing or faulty motor thermoswitch
wiring.
Amplifier undersized; active motor
torque to high.
3) Amplifier ambient temperatur to high.
0. Watchdog
When the display shows a "0." a
watchdog timeout occurred in the
processor. Drive / comms watchdog.
Interprocessor failure. Clear the error.
-|. Limit switch (clock wise) active
When the status monitor displays a "-|.", the CW-limit switch has been activated.
Probable Cause: Check wiring of X3.10 or limit switch
|-. Limit switch (counter clock wise) active
When the status monitor displays a "|-.", the CCW-limit switch has been
activated.
Probable Cause: Check wiring of X3.11 or limit switch
- Amplifier disabled
When the status monitor display is blank, the amplifier is disabled and there is no
fault. When the status monitor displays a "d", the amplifier has been disabled.
Probable Cause: The amplifier can be disabled by an input, a DIP switch, or by
the setup software.
F.
Fatal Following Error
When the status monitor displays a "F." the Following Fatal Error is activated
after following error exceeds the user defined Following Fatal Error band.
S
Stop - Mode
When the status monitor displays a "S" the control has been placed in the STOP
(previous HOLD) position mode.
Probable Cause: The hold position mode can be activated by an input X3.12, the
DIP-switch AS1.5, or by the setup software .
J Jog - Mode
When the status monitor displays a "J." the control is in "Jog" system mode. The
"Jog-Mode" can be stopped or started by the setup software.
