Description

o
00
No Fault
Displayed in P0-13 if no faults are recorded in the log.
01
Brake channel over current
Consult your local Invertek partner, the brake channel should not be connected in the
application when using a P2 Solar drive.
02
Brake resistor overload
Consult your local Invertek partner, the brake channel should not be connected in the
application when using a P2 Solar drive.
03
Instantaneous over current
on drive output.
Excess load on the motor.
Fault Occurs on Drive Enable
Check the motor and motor connection cable for phase – phase and phase – earth short
circuits.
Check the load mechanically for a jam, blockage or stalled condition.
Ensure the motor nameplate parameters are correctly entered, P1-07, P1-08, P1-09.
If operating in Vector mode (P4-01 – 0 or 1), also check the motor power factor in P4-05 and
ensure an autotune has been successfully completed for the connected motor.
Reduced the Boost voltage setting in P1-11.
Increase the ramp up time in P1-03.
If the connected motor has a holding brake, ensure the brake is correctly connected and
controlled, and is releasing correctly.
Fault Occurs When Running
If operating in Vector mode (P4-01 – 0 or 1), reduce the speed loop gain in P4-03.
.
04
Drive has tripped on
overload after delivering
>100% of value in P1-08
for a period of time.
Check to see when the decimal points are flashing (drive in overload) and either increase
acceleration rate or reduce the load.
Check motor cable length is within the limit specified for the relevant drive in section
Output Power and Current ratings
Ensure the motor nameplate parameters are correctly entered in P1-07, P1-08, and P1-09
If operating in Vector mode (P4-01 – 0 or 1), also check the motor power factor in P4-05 and
ensure an autotune has been successfully completed for the connected motor.
Check the load mechanically to ensure it is free, and that no jams, blockages or other
mechanical faults exist.
PSP
05
Hardware Over Current
Check the wiring to motor and the motor for phase to phase and phase to earth short circuits.
Disconnect the motor and motor cable and retest. If the drive trips with no motor connected,
it must be replaced and the system fully checked and retested before a replacement unit is
installed.
o
06
Over voltage on DC bus
The value of the DC Bus Voltage can be displayed in P0-20.
A historical log is stored at 256ms intervals prior to a trip in parameter P0-36.
This fault is generally caused by excessive regenerative energy being transferred from the load
back to the drive. When a high inertia or over hauling type load is connected.
If the fault occurs on stopping or during deceleration, increase the deceleration ramp time P1-
04 or connect a suitable brake resistor to the drive.
If operating in Vector Mode, reduce the speed loop gain P4-03.
If operating in PID control, ensure that ramps are active by reducing P3-11. Check the array
configuration to ensure that the Voc is not too high for the drive.
o
07
Under voltage on DC bus
This occurs routinely when power is switched off.
If it occurs during running, check the incoming supply voltage, and all connections into the drive,
fuses, contactors etc.
08
Heatsink over temperature
The heatsink temperature can be displayed in P0-21.
A historical log is stored at 30 second intervals prior to a trip in parameter P0-38.
Check the drive ambient temperature.
Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections
Enclosure mounting (IP20 Units)
3.6. Mounting the Drive – IP20 Units
,
3.8. Guidelines for mounting (IP66 Units)
–has been observed, and
that the cooling airflow path to and from the drive is not restricted.
Reduce the effective switching frequency setting in parameter P2-24.
Reduce the load on the motor / drive.
09
Under temperature
Trip occurs when ambient temperature is less than -10°C. The temperature must be raised over
-10°C in order to start the drive.
P

Factory Default parameters
have been loaded
Press STOP key, the drive is now ready to be configured for the required application.
11
External trip
E-trip requested on control input terminals. Some settings of P1-13 require a normally closed
contactor to provide an external means of tripping the drive in the event that an external device
develops a fault. If a motor thermistor is connected check if the motor is too hot.
