INTORODUCTION Thank you for purchasing the Mitsubishi Motion Controller/A173UHCPU/A172SHCPUN/A171SHCPUN. This instruction manual describes the handing and precautions of this unit. Incorrect handing will lead to unforeseen events, so we ask that you please read this manual thoroughly and use the unit correctly.
Page 3
For Sate Operations 1. Prevention of electric shocks WARNING Never open the front case or terminal covers while the power is ON or the unit is running, as this may lead to electric shocks. Never run the unit with the front case or terminal cover removed. The high voltage terminal and charged sections will be exposed and may lead to electric shocks.
Page 4
3. For injury prevention CAUTION Do not apply a voltage other than that specified in the instruction manual on any terminal. Doing so may lead to destruction or damage. Do not mistake the terminal connections, as this may lead to destruction or damage. Do not mistake the polarity (+/-), as this may lead to destruction or damage.
Page 5
CAUTION Use wires and cables within the length of the range described in the instruction manual. The ratings and characteristics of the system parts (other than control unit, servo amplifier, servomotor) must be compatible with the control unit, servo amplifier and servomotor. Install a cover on the shaft so that the rotary parts of the servomotor are not touched during operation.
Page 6
(3) Transportation and installation CAUTION Transport the product with the correct method according to the weight. Use the servomotor suspension bolts only for the transportation of the servomotor. Do not transport the servomotor with machine installed on it. Do not stack products past the limit. When transporting the control unit or servo amplifier, never hold the connected wires or cables.
Page 7
CAUTION When coupling with the synchronization encoder or servomotor shaft end, do not apply impact such as by hitting with a hammer. Doing so may lead to detector damage. Do not apply a load larger than the tolerable load onto the servomotor shaft. Doing so may lead to shaft breakage.
Page 8
(6) Usage methods CAUTION Immediately turn OFF the power if smoke, abnormal sounds or odors are emitted from the control unit, servo amplifier or servomotor. Always execute a test operation before starting actual operations after the program or parameters have been changed or after maintenance and inspection. The units must be disassembled and repaired by a qualified technician.
Page 9
(8) Maintenance, inspection and part replacement CAUTION Perform the daily and periodic inspections according to the instruction manual. Perform maintenance and inspection after backing up the program and parameters for the control unit and servo amplifier. Do not place fingers or hands in the clearance when opening or closing any opening. Periodically replace consumable parts such as batteries according to the instruction manual.
