Basic V/F characteristic of TMP series is shown in Fig. 6-12. Base
Frequency F
BASE
is the
output frequency corresponding to the rated output voltage U
N
. Its range is 10 to 400Hz.
Generally, F
BASE
should be selected according to rated frequency of the motor. In some special
case, it can be selected according to requirement. In this condition, both motor V/F characteristic
and output torque should be considered.

In order to compensate the torque drop at low frequency, the inverter can boost the output
voltage in the low frequency zone, which is shown in Fig. 6-13.
