Menu INPUTS
2.2 Set Point Menu
Two types of set points are available
-Internal set point: type in the chosen value, it can be modified by the operator with the
arrows on the keyboard. A ramp can be used for soft start. The ramp is activated when the
switch Regulator is turned on.
-External 0-10V set point: Potentiometer or PLC connected to "set point" pin.
The set point unit is given in menu DISPLAY.
Open loop case:
In this case, the parameter Max Effort must be given. It corresponds to the max product
tension.
This parameter is used to calibrate the system since there is no measure.
Example: CMC Magnetic Particle Brake (EMAG 26)
Nominal torque = 35 Nm at 1 A.
Bobine max diameter = 1 m.
Max current in brake = 0.5 A.
1/ from the EMAG 26 torque vs current, we obtain 0.5A = 22.5Nm.
2/ Max Effort = 22.5Nm / 0.5m = 45N.
Max Effort = 45N (or 4.5kg).
