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

CAUTION Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during operation. The servo motor with reduction gear must be installed in the specified direction to prevent oil leakage. Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo motor during operation. Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder may become faulty. Do not subject

(4) Usage CAUTION Provide a forced stop circuit to ensure that operation can be stopped and power switched off immediately. Any person who is involved in disassembly and repair should be fully competent to do the work. Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an accident. A sudden restart is made if an alarm is reset with the run signal on. Do not modify the equipment. Use a noise filter, etc. to minimize the influence of electromagnetic

(6) Maintenance, inspection and parts replacement CAUTION With age, the electrolytic capacitor of the servo amplifier will deteriorate. To prevent a secondary accident due to a fault, it is recommended to replace the electrolytic capacitor every 10 years when used in general environment. Please consult our sales representative. (7) General instruction To illustrate details, the equipment in the diagrams of this Instruction Manual may have been drawn without covers and safety guards. When the eq

COMPLIANCE WITH EC DIRECTIVES 1. WHAT ARE EC DIRECTIVES? The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January, 1997) of the EC directives require that products to be sold should meet their fundamental safety requirements and carry the CE marks

(4) Power supply (a) Operate the servo amplifier 7kW or less to meet the requirements of the overvoltage category II set forth in IEC60664-1. For this purpose, a reinforced insulating transformer conforming to the IEC or EN standard should be used in the power input section. Since the 11kW or more servo amplifier can be used under the conditions of the overvoltage category III set forth in IE644, a reinforced insulating transformer is not required in the power input section. (b) When supplying i

1. FUNCTIONS AND CONFIGURATION 1. FUNCTIONS AND CONFIGURATION 1.1 Introduction The Mitsubishi MELSERVO-J2-Super series general-purpose AC servo is based on the MELSERVO-J2 series and has further higher performance and higher functions. It is connected with a servo system controller or similar device via a serial bus (SSCNET) and the servo amplifier reads position data directly to perform operation. Data from a command unit controls the speed and rotation direction of the servo motor and executes
