*1: When using over 30VDC power supply, torque characteristics are improved but the driver temperature raise. The unit should be installed at the well ventilation environment.
*2: Based on ambient temperature 25 °C , ambient humidity 55%RH.
*3: RUN current varies depending on the input RUN frequency and max. RUN current at the moment varies also varies depending on the load.
*4: In case of MD5-HF14-AO, MD5-ND14, there are no DIVISION SELECTION, ZERO OUT function.
*5: Max. input pulse frequency is max. frequency to be input and is not same as max. pull-out frequency or max. slewing frequency
*6: The weight includes packaging. The weight in parenthesis is for unit only.
*: Environment resistance is rated at no freezing or condensation. |
