SMT-BD2
For the Sin/Cos encoder" configuration:
ƒ Check that the encoder signal jumpers COD are correctly set (position B2)
ƒ Check for the correct encoder supply voltage value
ƒ Check for the correct encoder-amplifier-motor ground and shield connections with regard to the
recommendations of
chapter 4 .
ƒ Check for the correct encoder A channel, B channel and R reference signal waveforms.

ƒ Check for the correct Motor encoder resolution parameter value.
ƒ Check that the number of encoder pulses between two successive R reference signals is an entire multiple of
the
Motor encoder resolution value. If this condition is not fulfilled, the encoder counting protection must be
disabled in order to cancel the "Counting" fault. The encoder counting protection can be inhibited by disabling
the encoder reference channel by means of the ZM jumper (
see section 2.8 "Encoder fault" ).
!
The encoder counting protection is checking that the encoder pulse count value between two
successive R reference signals is an entire multiple of the
Motor encoder resolution value. When the
encoder counting protection has been disabled, the amplifier is only checking that the encoder pulse
frequency is lower than 1.5 times the maximum encoder frequency. The maximum encoder frequency
is calculated into the amplifier according to the
Motor encoder resolution parameter value and the
Maximum speed parameter value. In this case, encoder pulse noise at a frequency lower than 1.5
times the maximum encoder frequency can involve uncontrolled motor movements that may be
dangerous for operator and machine.

ƒ Check the rated current value required with regard to the current table ( see chapter 2, section 1 ).
ƒ Check the amplifier rated current defined in the Rated current parameter with regard to the current required
for the operation cycle.
2.11 - "TRACKING"
FAULT
Check that the
Speed following error threshold parameter value is compatible with the required amplifier
operating cycle (speed profile and speed loop adjustments). If necessary, increase the Speed following error
threshold parameter value.
2.12 - "ADC"
FAULT
ƒ On SMT-BD2/b amplifiers equipped with the 16 bit ADC option, check for the correct orientation and the
correct mounting of the 16 bit ADC component.
ƒ Check that the input command wiring between controller and amplifier corresponds to the recommendations
of chapter 4 , and repeat the Offset compensation procedure.
ƒ If the fault still remains, the amplifier control board is not operating correctly.
