<Operating conditions>
The number of motor poles should be any of 2, 4 and 6 poles.
Single-motor operation (One motor for one inverter)
The wiring length from inverter to motor should be within 30m (98.42feet).
<Setting>
Parameter Setting Description
- - - Ordinary V/F control and torque boost (Pr. 0, Pr. 46) are valid.
98
0.1 to 3.7kW
(*)
Automatic torque boost control valid
(Set the applied motor capacity or one rank lower motor capacity.)
* The setting range changes with the inverter: 0.2kW to 3.7kW, - - - for the 400V
class.
Also when the Pr. 98 setting is other than "- - -", Pr. 3 "base frequency" and Pr. 19
"base frequency voltage" are valid.
When "- - -" or "888" is set in Pr. 19, the rated output voltage is selected.
CAUTION
* During operation using automatic torque boost, write to Pr. 3 and Pr. 19 is disabled
if "2" is set in Pr. 77.
