Attention:
On the usage of motors from other manufacturers, it is to be
ensured the motor temperature sensor used is adequately
isolated from the motor winding.
3.5.4 Project plan-
ning notes on
encoder con-
nection
The max. lines per revolution of the encoder can be calculated with the
following formula.
Example for n
max
= 6000 rpm, f
Grenz
= 150 kHz:
calculated: Pulses/rev.
selected: An encoder with 1024 pulses/rev.
Minimum motor speed
Formula to calculate the minimum displayable motor speed n
min
, depend-
ing on the lines per revolution of the encoder.
Note:
A speed < n
min
cannot be measured. In this range the actual
speed of 0 min
-1
is set. In the range 0 < n < n
min
the ampli-
fication of the encoder is reduced.
