POWER ELECTRONICS V5 Operation Instructions
26
F14 SCR1 FAULT
F15 SCR2 FAULT
F16 SCR3 FAULT
F17 SCR_S FLT
F14 Thyristor Fault L1, disconnected motor at L1.
F15 Thyristor Fault L2, disconnected motor at L2.
F16 Thyristor Fault L3, disconnected motor at L3.
F17 Thyristors Fault , disconnected motor.
Thyristor fault, motor disconnected, excessive number of starts, excessive temperature,
over voltage.
Check motor, cables and fans. Check thyristors and excessive environmental temperature.
Check input supply voltage.
If the problem persists, call Power Electronics or an authorised distributor.
This fault can only be reset via the display unit.
F18 EXCES T LS
Slow speed working time exceeded.
G12.2 Slow Speed T/O.
Excessive running time at slow speed.
Check the control. Check value of parameter G12.2 .
F19 LS DISABLE
Slow Speed not allowed.
Slow Speed mode is blocked if one of these 2 options are selected:
No phase sequence (G3.1 Phase Sequence) at the input. You need to select L1 L2 L3 or
L2 L1 L3 sequence. DC Brake stop selected (G13.1 DC Brake).
Set phase sequence at the input. Make sure no DC Brake is selected.
F20 COMS T/OUT
Serial communication Time Out exceeded.
No communication from the Master for the time specified at G14.1 CommTime Out.
RS232/RS485 communication link fault.
Check if the Master is trying to communicate to slave at a rate higher than specified at
G14.1 COM TIME O. Check the RS232/RS485 wiring. Check communication parameters.
F21 EXTRN TRIP
An external fault has occurred through a digital input.
There is a digital input activated and set as external fault.
Check configuration of digital inputs. Check the status of the digital inputs for correctness.
F22 CUR FLT
Large current unbalance is occurring among phases.
Large current unbalance occurs due to a sudden voltage drop in any of the V5 input
phases. Possible disconnection of one phase.
Check input power wiring. Check motor connection. Check supply voltage is correct.
In case of working with lamps for testing purposes at the output set the motor current to 1 A to
avoid this fault.
F23 CUR FLT 2
Large current unbalance is occurring among phases.
Large current unbalance occurs due to a sudden voltage rise in any of the V5 input
phases.
Check input power wiring. Check supply voltage is correct.
F24 HIGH PRESSURE
High pressure time protection.
The V5 is running and the pressure switch opens for longer than the time entered in
screen G16.4. Overpressure.
Check hydraulic installation. Check pressure switch. Check proper wiring from pressure
switch to V5 digital input 1. The V5 will require resetting on the display or via D INPUT 5 if
configured for 2 wire start/stop. Check parameter setting is done according to application
requirements.
