| Rated output voltage |
Output voltage is settable between 0% and 120% with the
output voltage adjustment function. Provided the rated voltage is 100%
output over the input voltage is disabled. |
| Rated output frequency |
0.5 to 320 Hz. Set to 0.5 to 60Hz by default. Maximum
frequency is adjustable between 30 and 320Hz. |
| Frequency setting resolution |
0.1Hz Analogue input = max 100Hz and 0.1Hz. |
| Frequency accuracy |
Analogue setting ±0.5% the maximum output frequency or
less at 25°C ±10°C. |
| Voltage Frequency Characteristics |
Factory preset at opened loop vector control suitable
for most constant torque application. Adjustable for special applications. |
Major
