General conditions
S The maximum speed/torque depend on the available converter output voltage
and the back EMF of the motor (calculation guideline: EMF must not exceed
rated converter voltage)
S Calculating the maximum speed:
n = V
max
Calculating k
S For the maximum torque as a function of the terminal voltage and duty cycle,
see the motor data sheets/planning guides.
S A motor encoder must be used in operation.
-- All encoders that can be connected to an SMC10 or SMC20 are supported.
Commissioning
The following steps are recommended for commissioning:
S Commissioning Wizard in STARTER
Motor identification and the "rotating measurement" (p1900) can be activated
when the commissioning Wizard is run in STARTER. Encoder adjustment
(p1990) is activated automatically together with the motor identification routine.
S Motor identification (standstill measurement (p1910))
Further information: See Subsection 3.2.11
S Encoder adjustment (p1990)
Further information: See Subsection 3.2.12
Warning
!
During initial commissioning and when the encoder is replaced, the encoder must
be adjusted (p1990).
S Rotating measurement (p1960)
Further information: See Subsection 3.2.11
