The V/Hz Characteristic Selection parameter determines the characteristic of the V/Hz
curve and whether any boost will be applied at starting. (The amount of boost may be au-
tomatically determined or set with parameter 502 (Voltage Boost).) The following data
values may be assigned:
The following data values may be assigned to this parameter:
Parameter Value Description
Linear Auto The Linear Auto selection operates the Vector algorithm and
activates current limiting functionality.
Linear Fxd V/Hz curve with the amount of boost fixed at the value set in
parameter 502 (Voltage Boost).
Pump Fxd V/Hz curve with the amount of boost fixed at the value set in
parameter 502 (Voltage Boost).
Fan Fxd V/Hz curve with the amount of boost fixed at the value set in
parameter 502 (Voltage Boost).
Linear 2pc Activates parameters 512 (Midpoint Frq) and 513 (Midpoint
Volt). These parameters are used to define a midpoint through
which the V/Hz curve passes so a custom curve may be creat-
ed for special motor applications.
Vector Activates the sensorless vector algorithm for high torque /
low speed operation. A vector-duty motor should be used for
this mode of operation. Vector mode does not use of the pa-
rameter (parameter 502).
