Page 2 INTORODUCTION Thank you for purchasing the Mitsubishi Motion Controller/Personal Machine Controller. This instruction manual describes the handling 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. Please make sure that this manual is delivered to the final user of the unit and that it is stored for future reference.
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 user's manual, or the instruction manual for the product you are using 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 that have a wire diameter, heat resistance and bending resistance compatible with the system. 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.
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 CAUTION Do not touch the lead sections such as ICs or the connector contacts. Do not place the control unit or servo amplifier on metal that may cause a power leakage or wood, plastic or vinyl that may cause static electricity buildup. Do not perform a megger test (insulation resistance measurement) during inspection.

Page 263 7. POSITIONING CONTROL CAUTION The operation that takes place on execution of a skip designated during constant-speed control, when an axis for which "degree" is designated as the unit and which has no stroke range is in- cluded, is described here. If, under these conditions, there is an ABS instruction following the skip, the final positioning point and the travel distance in the program as a whole will be the same ragardless of whether the skip is executed or not.

7. POSITIONING CONTROL 7.16.6 FIN signal wait function This is a function whereby, when the FIN wait function is selected and an M code is set for each point on the way, the end of processing of each point on the way is synchronized with the FIN signal, and positioning at the subsequent point is carried out when the FIN signal comes ON.

Page 301: M-Code Output Function
8. AUXILIARY AND APPLIED FUNCTIONS M-Code Output Function An M-code is a code number between 0 and 255 which can be set for each positioning control. During positioning control execution, these M-codes are read by the sequence program to check the current servo program and to command auxiliary operations, such as clamping, drill rotation, and tool changing.
Page 302 8. AUXILIARY AND APPLIED FUNCTIONS (3) Resetting M-codes The M-codes can be reset by clearing the M-code output devices to zero. Use this method during positioning control to carry out operations unrelated to the servo program, such as when it has been difficult to output the M-code during the previous positioning control.
Page 303: Backlash Compensation Function
8. AUXILIARY AND APPLIED FUNCTIONS Backlash Compensation Function The backlash compensation function compensates for the backlash amount in the mechanical system. When the backlash compensation amount is set, extra pulses equivalent to the backlash compensation amount are output after a change in travel direction resulting from positioning control, JOG operation, or manual pulse generator operation.

Page 309: Absolute Positioning System
8. AUXILIARY AND APPLIED FUNCTIONS Absolute Positioning System The absolute positioning system can be used for positioning control when using an absolute-position-compatible servomotor and MR- -B. Zeroing is not necessary using the absolute positioning system because after the machine position is initially established at system startup, the absolute position is sensed each time the power is turned on.
Page 310 8. AUXILIARY AND APPLIED FUNCTIONS (2) In the absolute positioning system, the absolute position may be lost under the following conditions: Re-establish the absolute position using zeroing or by aligning the machine position and using current value change. (a) After removing or replacing the battery unit. (b) On occurrence of a servo battery error (detected at servo amplifier power on).
Page 311 8. AUXILIARY AND APPLIED FUNCTIONS POINTS (1) The address setting range for absolute position system is −2147483648 to 2147483647. It is not possible to restore position commands that exceed this limit, or current values, after a power interruption. When performing an infinite feed operation, solve this problem by setting the units to degrees.

Page 365 APPENDICES Table 3.2 Special Register List (Continued) Number Name Stored Data Explanation When F numbers in the range F0 to 2047 are turned on by OUT F or SET F , they are entered in D9125 to D9132 in ascending order of register numbers. An F number which is turned off by RST F is erased from D9125 to D9132, and the contents of the data registers following the one where the erased F number was stored are each shifted to the preceding data register.
Page 366 APPENDICES POINTS (1) All special register data is cleared by the power-off, latch clear, and reset operations. The data is retained when the RUN/STOP key switch is set to STOP. (2) The contents of the special relays marked “Note-1” in the table above are not cleared even after the normal status is restored.
