Corrective Action
Displayed in P0-13 if no faults are recorded in the log
Ensure the connected brake resistor is above the minimum permissible level for the drive –
refer to the ratings shown in section 18.3.
Check the brake resistor and wiring for possible short circuits.
The drive software has determined that the brake resistor is overloaded (based on the values
entered in P3-13 and P3-14), and trips to protect the resistor. Always ensure the brake
resistor is being operated within its designed parameter before making any parameter or
system changes.
To reduce the load on the resistor, increase deceleration time, reduce the load inertia or add
further brake resistors in parallel, observing the minimum resistance value for the given
drive.
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.
I operating in Enhanced V/F mode reduce 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.
If operating a Gearless motor Check the encoder offset is correct, see section 12.7.
On Gearless closed loop system with motor rated frequency >32Hz or open loop Gearless
system ensure the motor back EMF voltage is correct, see section 12.4.
Fault Occurs When Running
If operating in Vector mode (P4-01 – 0 or 1, 3), reduce the speed loop gain in P4-03.
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 18.3
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
If operating a Gearless motor Check the encoder offset is correct, see section 12.7.
On Gearless closed loop system with motor rated frequency >32Hz or open loop Gearless
system ensure the motor back EMF voltage is correct, see section 12.4.
Refer to fault 3 above
Check that the lift has been correctly balanced.
Check that a brake resistor is connected correctly. (see section 6.4)
Check the resistance of the brake resistor complies with the values in section 18.3.
If the fault occurs on stopping or during deceleration, increase the deceleration time in P1-04
If operating in Vector Mode (P4-01 = 0-3), reduce the speed loop gain P4-03.
Check that the mains voltage level is within the range detailed in section 18.2.1
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 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.
If in rescue mode confirm that the voltage is within the range detailed in section 18.2.2
If in rescue mode try decreasing rescue speed (P2-05)
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 5.5 and 5.8 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
Trip occurs when ambient temperature is less than -10°C. The temperature must be raised
over -10°C in order to start the drive.
Press STOP key, the drive is now ready to be configured for the required application
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.
Communications lost with PC or remote keypad. Check the cables and connections to
external devices
