Fault Cause
Drive has exceeded maximum allowable
output frequency.
Regenerating energy is too high.
Stability or slip compensation circuit
adds frequency reference.
If H.016 ON, searching current is too
high. Motor is too small.
Cooling fan failure.
Excess motor current.
V/Hz: Torque boost too high, therm.
overload level too low.
Excess load on motor, for example, at
too low speeds.
Loss of phase connection.
Phase lost between drive and motor.
RPM above 130% Maximum Speed
(P.004), speed regulator response not
optimized.
Bad or disconnected cable between
Regulator and Power Module.
Drive parameters have been restored to
power-up defaults. Regulator has not
been configured to match Power
Module.
Power Module overload.
Too high DC Braking Current (H.007) or
Torque Boost (H.003).
Corrective Action
Vector: check parameters Encoder
PPR (U.001), Motor Poles (U.002), Base
Frequency (U.003).
V/Hz: check DC bus voltage; increase
deceleration time. Check values
Maximum Speed (P.004)/Overfreq.
(H.022). Check slip compensation
(H.004).
If H.016 ON, check motor size versus
Power Module size, recheck setting of
P.005 (too high).
Check ambient temperature, cooling fan,
minimum clearances around drive.
Vector: Check actual/Motor Rated
Nameplate Amps (U.004)
V/Hz: Check actual current/Torque Boost
(H.003).
Check that Power Module is sized
correctly.
Reduce load on motor (for example, at
low frequency).
Check that Power Module is sized
correctly. Reduce load on motor (e.g., at
low frequency).
Check output lines to the motor.
Check connections and cable of all 3
phases and motor windings. Replace
any damaged cable.
Check Encoder PPR (U.001), Motor
Poles (U.002), Base Frequency (U.003),
Motor Nameplate RPM Speed (U.005).
Check Reg. Proportional (U.012) ,
Integral Gain (U.013).
Check cables between Regulator board
and Power Module.
Power Module must be configured by
Reliance service personnel.
Check load to Power Module.
Check Power Module sizing versus
application. Check DC Braking Current
value (H.007). Check Torque Boost
(H.003).
