Analogue set value specification
Fig. 15: Set value determination for speed controller
The analogue input can process voltages from 0 V to 10 V.
An analogue set value specification of 10 V corresponds to the value specified in the
parameter n
setMax
.
A linear conversion is performed between 0 V and 10 V:
Speed-controlled operation: n
soll
= n
setMax
* (U
nsoll
/ 10 V)
Voltage controller: U = U
mot
* (U
nsoll
/ 10 V)
Depending on the motor type and the applied voltage, the set value specified in n
set-
Max
cannot be reached. In this case, the motor rotates at the maximum speed which
can be reached at the given voltage (see Tab. 1).
