Mitsubishi Electric FR-A701 Instrucion Manual page 74

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 either Mitsubishi standard motor with encoder, high efficiency motor (SF-JR, SF-HR two-pole,
·
four-pole, six-pole 3.7kW or more) or Mitsubishi constant torque motor (SF-JRCA four-pole, SF-HRCA 3.7kW or
more) or vector control dedicated motor (SF-V5RU). 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) connected.
