In such case please contact your sales person. D740-012 to 080–EC : Axxxxx, Bxxxxx, Cxxxxx, Dxxxxx, Exxxx and Fxxxxx D740-120 to 160–EC : Axxxxx, Bxxxxx, Cxxxxx and Dxxxxx D740-0.4K to 3.7K–CHT : Axxxxx, Bxxxxx, Cxxxxx, Dxxxxx,Exxxx and Fxxxxx D740-5.5K to 7.5K–CHT : Axxxxx, Bxxxxx, Cxxxxx and Dxxxxx Any misuse of safety function could lead to personal injury or death, property damage, or economic loss. To ensure that the system complies fully with requirement of safety, make a system-level risk assessment. Mitsubishi Electric Co. cannot assume responsibility for any system to comply with safety directive. ATTENTION The information of this manual is merely a guide for proper installation. Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored during installation. To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing any work on the drive. Measure the DC bus voltage at the P(+) and N(-) terminals or test points (refer to your drive’s User Manual for locations and discharging time). The voltage must be zero. The safety stop function do not isolate electrically between drive and motor. To avoid an electric shock hazard, disconnect/isolate power to the drive and verify to ensure that the voltage is zero before performing any work on the motor (refer to your drive’s User Manual for discharging time). 1. 1. Features Mitsubishi FR-D700 safety stop function prevents a drive from supplying rotational energy to motors. Dual safety channels ‘S1’ and ‘S2’ cut off the gate-drive power for IGBT to turn off. Fig.1 FR-D700 safety stop function diagram S2 S1 SC CPU Gate Driver Gate Driver IGBTs Input power M FR-D700 DANGER The safety stop function doesn’t isolate electrically between drive and motor. To avoid an electric shock hazard, disconnect power to the drive and verify that the voltage is zero before performing any work on the motor (refer to your drive’s User Manual for discharging time). Directives Mitsubishi FR-D700 safety stop function meets the following directives and categories. EN954-1 Category 3 IEC60204-1 Stop category 0 DANGER The misuse of safety function leads to personal injury or death, property damage, or economic loss. To ensure that the system complies fully with requirement of safety, make a system-level risk assessment. Mitsubishi Electric Co. cannot assume responsibility for any system to comply with safety directive. 1 2. 2. ATTENTION The following information is merely a guide for proper installation. Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored during installation. ATTENTION Ensure the safety relay unit and the D700 unit is mounted closely in enclosure meeting IP54 and all interconnection wiring is short and protected against open and short circuit faults. Refer EN/ISO13849-2. Installation Mitsubishi FR-D700 safety stop function should be used under following condition and environment. Table.1 The condition and environment for using safety stop function Item Condition Temperature range Operation -10Cto+50C (non-freezing) Storage -20Cto+65C Ambient humidity 90%RH maximum (non-condensing) Vibration 5.9m/s2 or less Altitude maximum 1000m above sea level Atmosphere Indoors (without corrosive gas, flammable gas, dust and dirt etc.) Over voltage category II or less Pollution degree II or less Mounting wall mounting / vertical orientation ATTENTION In order to meet safety stop, an approved safety relay unit to EN954-1 safety category 3 or better shall be used in conjunction with D700 as shown in example1,2. In addition, all other components with in the safety stop loop shall be ‘safety approved’ types. DANGER To avoid an electric shock hazard, insert the magnetic contactor (MC) between power source and drive. Open the contact of MC and keep away from drive for discharging time (refer to your drive’s User Manual for information) before performing any work on the drive. And verify that t...
