8  Faultfinding and remedy

Fault

Cause

Remedy

The motor will not start

supply voltage missing

check all fuses are good and supply voltage are
present

there is no current

drive not enable

Terminal X1/Pin5 should be connected to 0VDC
(op24V) for power stage enable

Motor wiring open

check the wiring for the armature circuit

The motor runs at an uncontrollably high
speed after switching on.

The control circuit is polarised

Change the polarity of the tachometer or the
motor.

The motor will not start although current
is present

The motor is blocked (mechanically)

Shorted motor circuit

Release the brake, if there is one; if necessary
dismantle the motor and run no-load test.
Check the wiring of the armature circuit

The motor runs unevenly

P-portion too high
I-portion too small

Turn P2 counter clockwise
Increase C8

Wiring fault at control leads or tachometer
leads

Check the shielding and check wiring

After enable the amplifier

Choke are not wired in the armature

check wiring

the red fault LED is lit

choke and/or motor inductance too low

the value must amount to, at least, the value for
the corresponding amplifier

short circuit in the motor, wiring or chokes

check wiring, motor and chokes

After turn on amplifier the red LED is lit
without enable amplifier

power stage is defective

exchange amplifier

the red LED is on after a long running
time

power stage overheat

let the module cool down

Red LED goes on when the motor is
decelerating

over voltage caused by high system inertia A braking regulator board needs to be added to

insure proper amplifier use

Red LED goes on immediately after
power up

Over voltage caused by high bus voltage

check transformer and net
