Before operation
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. (note that the capacity is
·
0.4kW or more)
· Motor to be used is either Mitsubishi standard motor with encoder, high efficiency motor (SF-JR, SF-HR two-pole,
four-pole, six-pole 0.4kW or more) or Mitsubishi constant torque motor (SF-JRCA, SF-HRCA 200V class four-pole
0.4kW to 55kW) 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) or sine wave filer (MT-BSL/BSC) connected.
