Еще емкость маловата.
Оттуда же:
Some servomotors, like disk type motors have very low coil resistance. Under around 2 Ohms
and when Supply voltage is greater then 100VDC, a so called energy-dump circuit is required
to protect the drive.
The problem occurs when the motor deccelerating rapidly, in this case, the motor works as a
generator and generates energy, which is pumped back into the power supply. This generates
a Voltage rise in the PSU and can damage the servo drive’s H-bridge, if the generated Voltage
exceeds 200VDC.
Safety warning!
These safety issues are very important, read them carefully and keep them
in mind in the first place:
The device can operate with low(0..50V) and medium (50..180V) voltages.
Above 50 Volts the controller’s metal case must be connected to safety
ground!
Motor and power supply terminals are bare M4 screws, the controller must
be build in a box, if supply Voltage is above 50V DC!
Touching the screws while device is under high voltage can cause personal
injury or even death!
An energy dump circuit must be used when supply voltage is greater than
100VDC and motor’s coil resistance is lower then 2Ohms, otherwise the
generated energy can cause permament damage in the device!
ЗЫ. Давай на ты, если не против.
