3.19. Reading Drive Parameters
A VT 100 terminal or a PC with a VT 100 emulation program can be connected
at connector X2 via an RS 232 interface to a DDC drive with analog command
value input or with a single-axis positioning module.
Drive parameters, such as amplilfication of velocity loops, can be output and
optimized, if necessary, via these interfaces at the time of commissioning.
Fault diagnostics are displayed in plain text in the event that service is needed.
Ready-made service cable INK 391 is available for connecting the DDC to a
PC (available lengths: 2, 5, 10 and 15 meters).

3.20. Regenerated Power
During braking, the energy stored in the drive is absorbed by the bleeder in the
DDC. Do not exceed continuous bleeder power. See data sheets for precise
data.
Continuous bleeder power is dependent upon rotary drive energy, potential
energy of unbalaned mass and the number of machine cycles completed.

When operating main drives in particular (2AD and 1MB), check
whether continuous bleeder power and maximum regenerated energy
during braking are not exceeded -- as per the data sheets.
