WARNING CAUSE WHAT TO DO
ID DONE The PS200 has performed the motor identification
magnetization and is ready for operation. This warning
belongs to the normal start-up procedure. x Continue drive operation.
ID MAGN Motor identification magnetization is on. This warning
belongs to the normal start-up procedure. x Wait until the drive indicates that motor identification is
completed.
ID MAGN REQ Motor identification is required. This warning belongs
to the normal start-up procedure. x
To start the ID magnetization:
x
Press the Start key.
ID NBR CHANGED The ID number of the drive has been changed from 1 in
Drive Selection Mode (the change is not shown on the
display). x To change the ID number back to 1 go to Drive Selection
Mode by pressing
DRIVE . Press ENTER . Set the ID number
to 1. Press ENTER.
ID RUN FAIL The Motor ID Run is not completed successfully.
x Check the maximum speed (Parameter 14.01) It should be
at least 80% of the nominal speed of the motor (Parameter
11.07).
ID RUN SEL
Motor Identification Run is selected, and the drive is
ready to start the ID Run. This warning belongs to the
ID Run procedure.
x Press Start key to start the Identification Run.
ID RUNNING Motor Identification Run is on. x
Wait until the drive indicates that Identification Run is
completed.
INV OVERLOAD Inverter overload condition; i.e., load is higher than
200% of /
2hd
2 seconds every 15 second or 150% of /
2hd
1 minute every 10 minutes.
Indication to the supervisory system is given.
x Check Torque and Current limit settings.
x Check ramp time setting (13.01 to 13.02) and Fieldbus RATE
signal.
x Check brake operation.
KEYPAD FAIL
(programmable Fault
Function 24.03)
A Keypad or Drives Window selected as active control
location for the PS200 has ceased communicating. x Check Keypad connector.
x Re-insert Keypad mounting platform.
x
Check Keypad Fail Fault Function parameters.
x Check Drives Window connection.
LINK or HWCP The fiber optic link to the NINT board is faulty or the
change rate of the output current has exceeded the
hardware overcurrent limit. x Check fiber optic cables between NINT and NGDR boards.
x Check motor load.
x Check acceleration time.
x Check motor and motor cable.
x Check that there are no power factor correction capacitors
or surge absorbers in the motor cable connected to the
drive output.
LOCAL CTRL LOSS Keypad or Drives Window selected as active control
location has ceased communicating.
x Check Keypad connector.
x Reinsert Keypad in the mounting platform.
x Check Drives Window connection.
LOW DEMAND The setpoint value requires regulation below minimum
speed. x Check for closed valve (downstream).
x Wait until demand is re-established (see Sleep Function
parameter 14.07).
LOW PERFORM The Pump Wear Monitor (PWM) has determined that
hydraulic wear in the pump has exceeded the set
threshold x Inspect pump casing and/or impeller for wear or internal
blockage
x Reset pump front clearance
x Re-run baseline characterization if hydraulic components
have been changed
MACRO CHANGE Macro is restoring or user Macro is being saved. x Please wait.
MANUAL OVERRIDE
Manual override function has been enabled. Either
through keypad or closure of DI-2
x Check state of digital input-2
x Check parameter 12.06 Manual Override
x If using a 3-wire start/stop method, change parameter 12.01
start/stop to 3-wire
MIN FLOW
(programmable Fault
Function 25.11)
The pump is operating below the safe continuous flow
rate. x Open the discharge check valve
x Check discharge line for blockages (debris, check valve not
opened).
x Check setting of parameter 25.12.
MOTOR PHASE
(programmable Fault
Function 24.17)
One of the motor phases is lost. This can be caused by
a fault in the motor, the motor cable, a thermal relay (if
used) or an internal fault. x Check motor and motor cable.
x Check thermal relay (if used).
x Check MOTOR PHASE Fault Function parameters. Disable
this protection.
MOTOR STALL
(programmable Fault F
unction 24.11 - 24.13)
Motor is operating in the stall region. This can be
caused by excessive load, locked rotor or insufficient
motor power. x Check if pump shaft has seized.
x Check motor load and the PS200 ratings.
x Check MOTOR STALL Fault Function parameters.
MOTOR STARTS Motor Identification Run starts. This warning belongs
to the IR Run procedure. x Wait until the drive indicates that motor identification is
completed.
MOTOR TEMP
(programmable Fault
Function 24.05, 24.08
Motor temperature is too high (or appears to be too
high). This can be caused by excessive load, insufficient
motor power, inadequate cooling or incorrect start-up
data.
x Check motor ratings, load and cooling.
x Check start-up data.
x Check MOTOR TEMP Fault Function parameters.
