CHAPTER 8 – Troubleshooting

SMT-BD2/m

2.10

FAULT

Check the rated current value required with regard to the current table (

see chapter 2, section 1

Check the amplifier rated current defined in the

Rated current

parameter with regard to the current required

for the operation cycle.

2.11

"POSITION"

FAULT

Check that the

following error threshold

parameter value is compatible with the required amplifier operating

cycle (speed profile and servo loop adjustments). If necessary, increase the

following error threshold

value.

2.12

"ADC"

FAULT

Check that the analog input command wiring corresponds to the recommendations of

chapter 4

, and repeat

the

Offset compensation

procedure.

If the fault still remains, the amplifier control board is not operating correctly.

3 - OPERATING PROBLEMS

3.1

OTOR SUPPLIED BUT NO TORQUE

Check

the

Maximum current

and

Rated current

parameters.

Check that the current limitation input (X4 pin 3) is not activated.

Check that the amplifier is not operating in torque mode (X4 pin 4 active) with zero input command or with
CV0 input activated.

3.2

OTOR DOES NOT MOVE

Check that the amplifier is on.

Check that the power supply is on.

Check the amplifier fuses (F1 and F2) and the motor connection.

Check the wiring of the signals FC+, FC-, Enable, Run and Wait.

3.3

HAFT LOCKED

ERATIC OSCILLATIONS OR ROTATION AT MAXIMUM SPEED

Check the encoder wiring on the X1 connector and the mechanical mounting of the encoder on the motor.

Check the value of the

Motor parameters

parameter in the

Advanced Functions

menu and repeat the

Auto-phasing

procedure with unloaded motor.

3.4

ISCONTINUOUS MOTOR ROTATION WITH ZERO TORQUE POSITIONS

Check the connection of the 3 phase cables between motor and amplifier.

3.5

OUD CRACKLING NOISE IN THE MOTOR AT STANDSTILL

Check that the motor-amplifier ground connections correspond to the recommendations of

chapter 4

Check the shield connection of the encoder cable.

3.6

OUD NOISE IN THE MOTOR AT STANDSTILL AND WHEN RUNNING

Check the rigidity of the mechanical transmission chain between motor and load (backlash and elasticity in

the gearboxes and couplings).

Execute

the

Auto-tuning

procedure again by choosing a lower bandwidth (

Medium

Low

If the problem remains, renew the

Auto-tuning

procedure by activating the

Antiresonance

filter.
