3.1 Important technical notes
3.1.1 Brake chopper
Feedback energy from the drive leads to a rise of the intermediate circuit voltage. The increased intermediate circuit
voltage is supplied to the voltage supply connector of the DC versions (DSV130 & DSV132). Make sure, that the
connected power supplies and consumers tolerate the increased voltage. If necessary, use a suitable diode to decouple
the voltage supply for the device.
The brake chopper starts to work when the intermediate circuit voltage exceeds the threshold of 30VDC (DSV132 &
DSV133: 75V), the generated braking energy is converted into heat energy by the internal respectively external braking
resistor. The continuous power rating of the brake resistor is electrically limited. If the braking energy can not be reduced
(e.g. due to the limited continuous power rating of the braking resistor), the intermediate circuit voltage rises until it
reaches the threshold of the over-voltage-protection of 32VDC (DSV132 & DSV133: 80V).
Using an external braking resistor is not possible for the DSV133 device.
When using an external braking resistor, the internal braking resistor has to be disabled by opening a soldering bridge
SJ1. The mean continuous power rating of the external brake resistor can be tuned by a protected parameter. If required,
please contact the manufacturer!
3.1.2 Lead fuses
The voltage supply of the servo controller DSV130 is internally fused with a lead fuse of 40A (DSV132 & DSV133:
30A). Only serious defects in the device can lead to a raise of the fuses, therefore changing the fuses by the user is not
intended. Please send any device with damaged fuses back to the manufacturer.
3.1.3 Lifetime
The DSV’s lifetime is mainly governed by the strain put on the dc-link capacitors. At an ambient temperature of 45°C
and 3.0A rated output current, a lifetime of 20,000h can be expected. The lifetime increases with reduced output
current or lower ambient temperature.
