7-10 Trips and Fault Finding 590 Series DC Digital Drive
Trip Message and Meaning Possible Reason for Trip
5703 RCV ERROR
Invalid data received via P3 port from another Drive
(Alarm only operates when MODE parameter is set to 5703 SLAVE)
STALL TRIP
With motor stationary (AT ZERO SPEED parameter
shows TRUE), current has exceeded the STALL
THRESHOLD parameter value for longer than the
STALL TRIP DELAY parameter value
(Alarm only operates when the STALL TRIP parameter is enabled).
OVER I TRIP
Current feedback value has exceeded 280% of rated
current
(300% loading not exceeding 15ms or 325% not exceeding 6.6ms is acceptable)
Motor armature windings failure - check insulation resistance.
Badly tuned current loop
Faulty Drive - refer to Parker SSD Drives
ACCTS FAILED
AC current transformer plug connection to Drive
power board missing
Check armature current transformer plug for correct installation.
Note:
The trip prevents the contactor closing and the current loop activating
without armature current feedback - important in the case of external stack
controllers where the thyristor stack is remote from the control board.
AUTOTUNE ERROR
Error has been encountered during the Autotune
process to include:
Speed feedback has exceeded 20% of rated speed
Field current feedback has exceeded 6% of rated
field current
The motor shaft was rotating, or was caused to rotate.
The field current was seen to exceed 6%, when a field-off Autotune had been
selected, or the field current stopped during a field-on Autotune.
The drive to armature wiring was open-circuit.
The discontinuous current boundary was found to exceed 200% of the motor
armature current rating (refer to Chapter 5: "Control Loops" - Manual Tuning)
Large imbalance in the three-phase voltages of the supply (refer to Chapter 5:
"Control Loops" - Manual Tuning)
A hardware fault relating to current feedback was detected on the control board.
AUTOTUNE ABORT
The Autotune sequence has been aborted.
Coast Stop, Program Stop, Enable or Start Run terminal(s) disabled during
Autotune sequence
The AUTOTUNE parameter reset during the Autotune sequence
Autotune sequence has timed-out (approximately 2 minutes).
SEQ PRE READY
Coding not present.
Replace power board or chassis.
REMOTE TRIP
REM. SEQUENCE parameter Remote Trip flag set to zero.
