of bipolar setpoint selection
(−10 V ... + 10 V)
l C0010 only limits the analog
input 1
l In the case of a max. output
frequency > 50 Hz the
switching threshold of the auto
DCB in C0019 has to be
increased.
l From software 3.5: If
C0010 > C0011, the drive does
not start when controller
enable is set.
à Speed setting range 1 : 6 for
Lenze geared motors: For
operation with Lenze geared
motors has to be set
necessarily.
