3.1.6.3.3 Remedy for under-voltage
Possible causes for under-voltage include:
the voltage supplied to the drive is continuously below the defined threshold.
Note
It is normal to have a small (<1V) drop in voltage in the circuit due to resistance.
The power supply should be set to output a voltage slightly higher than the threshold or the threshold should
be set lower in this regard. For better investigation, measure the voltage with a multimeter:
1.
2. The voltage between the main power supply pins on the drive
3. The voltage output by the power supply
The three results should be close. Otherwise, if there are large difference between the first two results, the
hardware may be damaged. If the first two results are close, and the third is different, there may be a big
voltage drop in the supply circuit due to factors such as cable resistance.
If the error occurs during motion, the voltage output of the power supply drops when the maximum
output current is reached. Check the specification of the power supply and make sure that a supply with
adequate power rating is used.
3.1.6.3.4 Remedy for over-temperature
When the temperature of the drive is too high, it is usually a sign of inadequate cooling. First, please check
the values in
Core temperature subitem 1: Measured temperature
and note down the values. If the values seem much higher than a reasonable value,
please contact Synapticon technical support. Please refer to our thermal installation guide for further
information about improving the cooling.
