Supplying with power supply unit
The power supply unit used must
l
be able to charge the capacitive load of the DC link capacitors with current
limitation when switched on.
l
be able to tolerate the high voltage at [X9] occurring during braking without raising
an error.
Additional external buffer capacitors can be used to buffer the braking energy.
BL 4800-M / BL 4800-D: Danger of destroying the power supply unit
During braking, a high voltage can be present at [X9], which can destroy the power
supply unit. To prevent this, the switch-off threshold in case of overvoltage must be
suitably parameterised (see section
Power supply via main power unit
in the Product
manual smartServo BL 4000-D / smartServo BL 4000-M).
High charging current when battery is connected
When connecting a battery, a high compensating current (>1000 A) flows until the
internal capacitors of the servocontroller are charged. We therefore recommend initially
connecting the battery via a 1k
Ω
resistor for precharging.
