Calculation/conversion setpoints/actual values
5.1 Speed setpoint input and evaluation of the speed actual value
Speed setpoint with/without encoder
● With encoder
The value to be sent to the bus is calculated as follows:
If the target velocity should be, e.g.: 3000 rpm, then the following must be sent to the bus
to SINAMICS, for an encoder with a pulse number 2048 and a fine resolution of 11:
● Without encoder
Process data interface
If the incoming speed setpoint is read in parameter r8860[x], this is formed from the following
calculation:
In order to see the process value specified via the bus referred to 4000 000 hex in r8860[x],
then p2000 must be set to p0311.
Note
For an operating mode without encoder, an encoder can still be commissioned. Example: for
encoderless closed-loop speed control (p1300 = 20) or encoderless closed-loop torque
control (p1300 = 22). For these operating modes, the velocity is calculated using the formula
"with encoder".
