5.3 Maintenance and inspection procedures
The procedures for carrying out the periodic maintenance and inspection are described in this section. Thoroughly
read the contents, and follow the instructions. This work can be commissioned to the Mitsubishi Service Depart -
ment for a fee. (Never disassemble, etc., the parts not described in this manual.)
The maintenance parts, etc., required for the customer to carry out maintenance and inspection are described in
Page 147, "5.5 Maintenance parts"
CAUTION
5.3.1 Robot arm structure
An outline structure drawing is shown below.
(1) RV-2FR series
1) The rotation of the J1 axis motor <1> arranged in the base is conveyed to the reduction gears <3> via the
timing belt <2> to rotate the J1 axis.
RV-2FR/2FRL: Brakes are not mounted in the J1 axis motor.
RV-2FRB/2FRLB: Non-excitation magnetic brakes are mounted in the J1 axis motor.
2) The rotation of the J2 axis motor <4> arranged in the No.1 arm is conveyed to the reduction gears <6> via
the timing belt <5> to rotate the J2 axis.
Non-excitation magnetic brakes are mounted in the J2 axis motor.
3) The rotation of the J3 axis motor <7> arranged in the No.1 arm is conveyed to the reduction gears <9> via
the timing belt <8> to rotate the J3 axis.
Non-excitation magnetic brakes are mounted in the J3 axis motor.
4) The rotation of the J4 axis motor <10> arranged in the elbow is conveyed to the reduction gears <12> via
the timing belt <11> to rotate the J4 axis.
RV-2FR/2FRL: Brakes are not mounted in the J4 axis motor.
RV-2FRB/2FRLB: Non-excitation magnetic brakes are mounted in the J4 axis motor.
5) The rotation of the J5 axis motor <13> arranged in the No.2 arm is conveyed to the reduction gears <16> via
the timing belt <14> to rotate the J5 axis. Non-excitation magnetic brakes <17> are mounted via the timing
belt <15> in the J5 axis motor.
6) The J6 axes differ as follows depending on the type
RV-2FR/2FRL: The rotation of the J6 axis motor <18> arranged in the No.2 arm is conveyed to the
RV-2FRB/2FRLB: The rotation of the J6 axis motor <18> arranged in the No.2 arm is conveyed to the
