Mitsubishi Electric Melservo-Jet MR-JET-G Series Operation & User’s Manual

2.1 Control mode ■Method 33 and Method 34 (Homing on index pulse) The following figure shows the operation of Homing method 34. The homing direction of Homing method 33 is opposite to that of Homing method 34. • When homing is performed from near the Z-phase, the homing completion position varies. The recommended start position for homing can be found by rotating the servo motor about a half-turn away from the homing direction. • When the stroke end is detected ■Method 35 and Method 37 (Homing on current position) The following figure shows the operation of Homing ...

2.1 Control mode 59 2 ■Method -9 and -41 (dog type last Z-phase reference homing) The following figure shows the operation of Homing method -9. The homing direction of Homing method -41 is opposite to that of Homing method -9. *1 After the front end of the proximity dog is detected, if the rear end of the proximity dog is detected without stop, [AL. 090] occurs. Revise the length of the proximity dog, or revise both the homing speed and creep speed. • When homing is started from the proximity dog • When the servo motor returns at the stroke end *1 This cannot be used w ...

3.11 Forced stop deceleration function Timing chart When EM2 (Forced stop 2) is turned off, the servo motor decelerates in accordance with the value of [Pr. PC24 Deceleration time constant at forced stop]. Once the servo motor speed becomes below [Pr. PC07 Zero speed] after completion of the deceleration command, the base circuit will be shut off and the dynamic brake will activate. ON OFF ON OFF 0 r/min [Pr.
