DRIVING THE MOTOR
POINT
If the conditions below are not satisfied, malfunction such as insufficient torque and uneven rotation may occur.
· The motor capacity should be equal to or one rank lower than the inverter capacity.
· Motor to be used is any of Mitsubishi standard motor with encoder (SF-JR 3.7kW or higher), high efficiency motor
with encoder (SF-HR 3.7kW or higher) or Mitsubishi constant torque motor with encoder (SF-JRCA 4P, SF-HRCA
3.7kW or higher) or vector control dedicated motor (SF-V5RU (1500r/min series)). When using a motor other than
the above (other manufacturer's motor), perform offline auto tuning without fail.
· Single-motor operation (one motor run by one inverter) should be performed.
· Wiring length from inverter to motor should be within 30m. (Perform offline auto tuning in the state where wiring
work is performed when the wiring length exceeds 30m.)
CAUTION
· Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Make
setting after confirming the function of each terminal.
· Do not perform vector control with a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) connected.
