Possible Reason for Trip
Software overcurrent trip:
• If the current exceeds 180% of stack rated current for a
period of 1 second, the drive will trip. This is caused by
shock loads. Remove the shock load.
•
ACCEL TIME and/or FIXED BOOSTset too high
• DECEL TIME set too low
The motor is drawing too much current (>100%) at zero
output frequency:
• FIXED BOOST level set too high
10V fault:
•
+10V REF overload warning (terminal 4) -
10mA maximum
Desaturation:
• Instantaneous overcurrent. Refer to OVERCURRENT in
this table.
The dc link ripple voltage is too high:
• Check for a missing input phase
Brake resistor overcurrent:
•
Check brake resistor value is greater than minimum
allowed
AOUT overload on terminal 5:
•
10mA maximum
DIN3 overload on terminal 9:
•
20mA maximum
DOUT2 overload on terminal 10:
•
50mA maximum
Unknown trip
Zero I Current Calibration:
• Current sensor calibration fault. Switch unit off/on. If
persistent, return to factory.
Switch unit off/on. If persistent, return unit to factory
Press the key to accept the default configuration. If
persistent, return unit to factory
