Functional Description
This block defines the parameters needed to build the following curve. It is used to limit the motor’s
current, depending on the speed.
If the motor permanent current is defined as a constant on the whole range of use, the following parameters
must be set to :
-
MPS1 = MPS2 = MPS3 = AC input voltage (in Vrms)
- CURRENT AT MPS1 = CURRENT AT MPS2 = CURRENT AT MPS3 = PERM CURRENT from
MOTOR PMAC 1 function block
- SPEED AT MPS1 = SPEED AT MPS2 = SPEED AT MPS3 = MAX SPEED from MOTOR PMAC 1
