Operating Instructions, 07/07, A5E00288214A
Standard with variable voltage boost
Characteristic that compensates for voltage
losses in the stator resistance for static /
dynamic loads (flux current control FCC).
This is particularly useful for small motors,
since they have a relatively high stator
resistance.
Characteristic that takes into account the
motor torque curve (e.g. fan/pump).
Quadratic characteristic (f² characteristic)
•
Energy saving because the low voltage
•
also results in small currents and losses.
Characteristic that takes into account the
motor/machine torque characteristic.
Characteristic (see parameter value 0) that takes into account the technological
particularity of an application (e.g. textile applications):
Whereby current limitation (Imax controller) only affects the output voltage and not
•
the output frequency.
By disabling slip compensation.
•
Setpoint channel and closed-loop control
