1. To prevent electric shock, note the following: WARNING Before wiring or inspection, switch power off and wait for more than 10 minutes. Then, confirm the voltage is safe with voltage tester. Otherwise, you may get an electric shock. Connect the servo amplifier and servo motor to ground. Any person who is involved in wiring and inspection should be fully competent to do the work. Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, you may get

4. Additional instructions The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock, etc. (1) Transportation and installation CAUTION Transport the products correctly according to their weights. Stacking in excess of the specified number of products is not allowed. Do not carry the servo motor by the cables, shaft or encoder. Do not hold the front cover to transport the servo amplifier. The servo amplifier may drop. Install the servo am

(2) Wiring CAUTION Wire the equipment correctly and securely. Otherwise, the servo motor may misoperate. Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF option) between the servo motor and servo amplifier. Connect the output terminals (U, V, W) correctly. Otherwise, the servo motor will operate improperly. Do not connect AC power directly to the servo motor. Otherwise, a fault may occur. The surge absorbing diode installed on the DC output signal relay must be wir

(5) Corrective actions CAUTION When it is assumed that a hazardous condition may take place at the occur due to a power failure or a product fault, use a servo motor with electromagnetic brake or an external brake mechanism for the purpose of prevention. Configure the electromagnetic brake circuit so that it is activated not only by the servo amplifier signals but also by an external emergency stop signal (EMG). Contacts must be open when servo-on signal is off, when an Circuit must be alarm (

(5) Grounding (a) To prevent an electric shock, always connect the protective earth (PE) terminals (marked ) of the servo amplifier to the protective earth (PE) of the control box. Connect PE terminal of the control box to the NEUTRAL of a power supply. Be sure to ground the NEUTRAL of a power supply. (b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect the cables to the terminals one-to-one. PE terminals PE terminals (c) If a leakage current breaker

1. FUNCTIONS AND CONFIGURATION 1. FUNCTIONS AND CONFIGURATION 1.1 Introduction The Mitsubishi MR-E series general-purpose AC servo is based on the MR-J2-Super series, and has the same high performance and limited functions. It has position control and internal speed control modes. Further, it can perform operation with the control modes changed, e.g. position/internal speed control. Hence, it is applicable to a wide range of fields, precision positioning and smooth speed control of machine tools
