Please read here first Thank you for choosing the Mitsubishi Magnetic Motor Drive Unit. This instruction manual gives handling information and precautions for use of the drive unit. Incorrect handling of the equipment may cause an unexpected fault. To optimize the unit capability, please read this manual carefully before using the equipment. General precautions Please forward this instruction manual to the end user.
Please read here first (Continued) Safety Instructions This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the drive unit until you have read through this instruction manual and appended documents carefully and can use the equipment correctly. Do not use the drive unit until you have a full knowledge of the equipment, safety information and instructions.
1. Usage WARNING The MELIPM series motor is a synchronous motor with high-performance magnets built in its rotor. Therefore, after the drive unit is powered off, there are high voltages at the motor terminals while the motor is running. Before starting wiring or maintenance and inspection, make sure that the motor has stopped.
4. Wiring WARNING Any person who is involved in the wiring of this equipment should be fully competent to do the work. Otherwise, an electric shock or fire can occur. Install a no-fuse breaker or earth leakage circuit breaker. Otherwise, a drive unit failure can cause large currents to flow, resulting in a fire. Always install the unit before wiring. Otherwise, an electric shock or fire can occur.
5. Operation WARNING Always replace the front cover before switching input power on. While power is on, do not remove the front cover. Doing so can cause an electric shock. Operate the switches with dry hands. Not doing so can cause an electric shock. Prepare an emergency stop switch separately. The "STOP/RESET" key of the parameter unit is valid for stopping only when the function setting has been made. Not using a separate emergency stop switch can cause accidents.
6. Maintenance, Inspection and Part (Cooling Fan) Replacement WARNING Any person who is involved in maintenance, inspection or part replacement should be fully competent to do the work. Otherwise, an electric shock or injury can occur. Before starting maintenance, inspection or part replacement, make sure that the motor is at a stop, wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do the work.

8 PARAMETER FUNCTIONS 8.7.2 Selection of the control circuit output terminal functions Pr. 190 Pr. 194 "RUN terminal function selection" "FU terminal function selection" You can select/change the functions of the control circuit output terminals. At the initial values, the terminal names and signal names match. Setting Signal Name 0 RUN 3 OL 4 FU 12 Y12 21 UVT 25 FAN 98 LF 99 ABC 9999 Operation "ON" during motor operation, "OFF" during voltage braking operation or stop.
8 PARAMETER FUNCTIONS Once the motor speed has reached or exceeded the speed set in the corresponding parameter, it is exported from the control circuit output terminals where the FU signal has been assigned. Pr. 43 is valid for only the operation performed using the reverse rotation signal (terminal STR or REV key). Setting the Pr. 43 value makes the Pr.
8 PARAMETER FUNCTIONS 8.7.5 Selection of the instrument connection terminal functions Pr. 54 "FM terminal function selection" You can select the signals output to the FM terminal designed for instrument connection. Setting 1 2 5 MEMO Display Data Motor speed Motor current Preset speed Unit r/min A r/min Full-Scale Value set in Pr. 55 Value set in Pr. 56 Value set in Pr. 55 The maximum number of pulses of the terminal FM is 2400 pulses/s.
