Notes
For asynchronous
motors only with Servo
With V/f control the
speed can be kept
constant by means of
selectable slip
compensation.
The sampling rate has
an important influence on
the dynamic control
response.
When "Isochronous
PROFIBUS" is selected,
the controller cycles are
automatically adjusted to
125 μs, 250 μs, 375 μs
and 500 μs.
Note limit voltage (2 kV)
and use of VPM Module
with synchronous
motors; see catalog
PM21.
With Servo control
combined with encoder
and appropriate special
motors, field weakening
up to 16 times the field-
weakening threshold
speed is poss ble.
These values refer to
synchronous motors of
type 1FK7/1FT6.
Please note the limit
voltage (kE factor) for
motors from external
suppliers.
