INV FAULT AVOID SEL (P.312) settings and action taken when drive detects conditions that could lead to
an inverting fault.
Parameter Setting
Is Drive
Regenerating or
Attempting to
Regenerate? Drive Action
DISABLED n/a None
FAULT
IMMEDIATELY Yes • immediately stops (coast/DB)
• generates the fault F00015 ( INVERTING FAULT AVOIDED).
FAULT
IMMEDIATELY No (drive is
motoring)
• generates the alarm A00005 ( INVERTING FAULT AVOIDED) .
• continues normal operation on the motoring bridge until a
request to regenerate is detected.
• When a request to regenerate is detected, the drive immediately
stops (coast/DB) and generates the fault F00015 (INVERTING
FAULT AVOIDED)
DELAY BEFORE
FAULT Yes • Immediately forces the Current Minor Loop reference to zero
• Logs the alarm A0005 ( INVERTING FAULT AVOIDED)
• Continues to operate normally for up to two seconds. The drive
can generate a motoring current as needed but will coast while a
demand for regenerative current exists.
• If the demand for regenerative current persists for more than
two seconds, the drive:
- stops (coast/DB) and
- generates the fault F00015 (
INVERTING FAULT AVOIDED).
• If the conditions that caused the alarm return to normal within
two seconds, the drive returns to normal operation (the
regenerative bridge will be re-enabled) without stopping.
DELAY BEFORE
FAULT No (drive is
motoring)
• Logs the alarm A0005 ( INVERTING FAULT AVOIDED).
• Continues normal operation on the motoring bridge until a
request to regenerate is detected.
• When a request to regenerate is detected, the drive continues to
operate normally for up to two seconds. The drive can generate a
motoring current as needed but will coast while a demand for
regenerative current exists.
• If the demand for regenerative current persists for approximately
two seconds, the drive:
- stops (coast/DB)
- generates the fault F00015 (
INVERTING FAULT AVOIDED).
• If the conditions that caused the alarm return to normal within
two seconds, the drive returns to normal operation (the
regenerative bridge will be re-enabled) without stopping.
IR COMPENSATION (P.206)
Sets the armature voltage loss compensation value used when the drive is configured as a voltage
regulator. This parameter is also used by the field current regulator to set the field weakened threshold.
Parameter Range: 0 to 50% of MOTOR RATED ARM AMPS (P.008)
Default Setting: 0%
Parameter Type: Tuneable
