TOPVERT L1 Series
E- 30
PU communication error
(Pu) {23}
 Check whether the keypad communication
circuit is
well-conducted
Auto tuning failure
(tunE) {24}
 Check cabling between drive and motor.
 Check whether the motors horsepower
corresponds to the drive output power.
 Retry again
Braking chopper fault
(bF) {25}
 Switch off power supply wait until display off then
on again, If fault code is still displayed please
return to the factory.
Phase-Loss protect or
capacitor aged
(PHL) {27}
Three phase imbalanced at
the input voltage or the drive
detects excessive ripple
voltage on DC-Bus
Caused
of
pow
er source:
 Check whether the power voltage is normal
 Check whether the screw at the input power
terminal is tightened
 Check whether the power source phase-lacking
Caused of smoothing capacitor:
 Check whether the smoothing capacitors life is
ended.
Current signal error during
stop
(CC) {28}
 Reset the drive, if okay, then might be interference
noise come into the drive.
 Return to the factory if previous method is not
effect.
CPU error
(CPu) {29}
Electronics Circuit Fault
 Switch off power supply wait until display off then
on again, If fault code is still displayed please
return to the factory.
Fan fault
(FAn) {30}
 Check whether the cooling fan is blocked
 Replace the fan
Analog input error
(AnI.) {31}
 Check if the analog input signal is out of range
Over-Torque2 detected
(ot2) {32}
 Check whether the motor 2 is overloaded
 Check whether motor 2 rated current setting
(Pr5-40) is suitable
 Check whether the Over-Torque2
detect parameter
are suitable (Pr5-21~Pr5-23)
 Check whether the mechanical system is normal
 Increase motor 2 capacity and replace
the drive
with the next higher power model
Motor overload
-Thermal relay 2
(oL2) {33}
(Electronic thermal relay 2
protection.)
 Check whether the motor 2 V/F setting proper
 Check whether the motor 2 r
unning low speed for
long period
 Check for possible motor 2 overload
 Check motor 1 full load current (Pr5-40)
 Check electronic thermal overload 1 setting
(Pr5-45 to Pr5-46)
 Reduce the load so that the drive output current
does not exceed the value set on Pr5-40
 Increase motor capacity
Motor select error
(rnot) {34}
 Check the motor wiring connection
 Check the parameters settings
