Parameter List For simple variable-speed operation of the inverter, the initial setting of the parameters may be used as they are.
Explanations of Parameters The abbreviations in the explanations below are as follows: Page 21 Terminal Type Terminal Name Description Symbol 1 changeover contact output indicates that the inverter protective function has activated and Relay output 1 alarm the output stopped.
Heatsink protrusion procedure When encasing the inverter in an enclosure, the generated heat manuzl in an enclosure can be greatly reduced by installing the heatsink portion of the inverter outside the enclosure. To print the manual completely, please, download it. Main circuit terminal Option supplied with the 75K or more.
