    ● A person who took a proper engineering training. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations. ● A person who can access operating manuals for the protective devices (e.g. light curtain) connect- ed to the safety control system.
  • Page 6 Electric Shock Prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. ● Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
  • Page 7 Fire Prevention CAUTION: ● Mount the inverter to incombustible material. Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mount- ing it to or near combustible material can cause a fire. ●...

  • Page 9 Wiring CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. These devices on the inverter output side may be overheated or burn out. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained.
  • Page 10 CAUTION: ● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. ● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
  • Page 11 Emergency stop CAUTION: ● Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. ● When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.

    Parameters (F) Setting of acceleration/deceleration time and acceleration/deceleration pattern 5.8.3 Remote setting function Even if the operation panel is located away from the enclosure, contact signals can be used to perform continuous variable-speed operation, without using analog signals.

  • Page 430 (F) Setting of acceleration/deceleration time and acceleration/deceleration pattern Parameters The multi-speed operation function is invalid when remote setting function is selected. Setting frequency is "0". Even when the remotely-set frequency is cleared by turning ON the RL (clear) signal after turning OFF (ON) both the RH and RM signals, the inverter operates at the remotely-set frequency stored in the last operation if power is reapplied before one minute has elapsed since turning OFF (ON) both the RH and RM signals.

When the start signal was turned OFF during start-time hold, deceleration is started at that point. At switching between forward rotation and reverse rotation, the starting frequency is valid but the start-time hold function is invalid.
