7) Operating a permanent magnet motor
Setting of V/F control mode selection


(PM motor control)
Permanent magnet motors (PM motors) that are light, small in size and highly efficient, as compared to
induction motors, can be operated in sensor-less operation mode.
Note that this feature can be used only for specific motors. For more information, contact your Toshiba
distributor.
8) Setting of V/f characteristic arbitrarily
Setting of V/f control mode selection
pt
to
7
(V/f 5-point setting)
In this mode, the base frequency and the base frequency voltage for the V/f control need to be set to operate
the motor while switching a maximum of 5 different V/f characteristics.

Note 1: Restrict the value of torque to boost ( vb ) to 3% or so. Boosting the torque too much may impair the
linearity between points.
Note 2: Please note if the inclination of each V/f is too high (exceeding 8.25%/Hz), a - 02 (Points setting alarm 2)
will occur.
