※Since torque characteristics are improved but the driver temperature rises with the 30VDC power supply, the driver should be installed at the well ventilated environment. Torque is variable by power supply.
※Max. current consumption: Based on the ambient temperature 25℃, ambient humidity 55%RH.
※RUN current varies depending on the input RUN frequency, and the max. instantaneous RUN current varies also.
※Max. input pulse frequency is max. frequency to be input and is not same as max. pull-out frequency or max. slewing frequency.
※The weight includes packaging. The weight in parenthesis is for unit only.
※Environment resistance is rated at no freezing or condensation.

  PMC-1HS/2HS Series

  The PMC-1HS/2HS series high-speed programmable motion controllers are stand-alone controllers capable of 1 or 2-axis control. The controllers also feature high-speed processing up to 4 Mpps and 4 operation modes (scan, continuous, index, program). 64 steps of programming is possible with a combination of 12 control commands. Operation programming, parameter configuration and editing can be done easily with the dedicated software.
