User manual HITACHI SJ-FB

[. . . ] FOR HITACHI INVERTER SJ-FB (Feed-Back Board) INSTRUCTION HITACHI NB616XB Thank you for purchasing the SJ-FB (HITACHI FEED-BACK BOARD). This manual explains the operation of the feed-back board for use with SAFETY To get best performance with SJ-FB (Feedback Board), read this manual, the SJ300 Instruction Manual, and all of the warning labels attached to the inverter carefully before installation and operation, and follow the instructions exactly. Keep this manual handy for your quick reference. Definitions and Symbols A safety instruction (message) is given with a hazard alert symbol and a signal word - WARNING or CAUTION. Each signal word has the following meaning throughout this manual. This symbol means hazardous high voltage. [. . . ] P026=66Hz / 60Hz=1. 1 P026=66Hz / 60HzX100=110. 0 No. 1 2 (Note 4) The SJ300 Production number (MFG No) is printed on the main body of the SJ300 specifications label. Refer to figure 5-2(1), figure 5-2(2).

NO YES Set SWENC1 switch OFF. Set SWENC1 switch ON. Detect a wire break of the Z phase signal? NO YES Set SWENC2 switch ON. Set SWENC2 switch OFF. Use the pulse train position command input? YES NO Connect parallel motors to the pulse train position command input? NO YES Turn SWR1, 2 on only 1 unit that is the most distant from a master inverter in a plural motor. Set SWR1, 2 switch ON. END Figure 5-3 Switch setting flowchart 20 Chapter 6 OPERATION Refer to [Chapter 3 OPERATION] in the instruction manual for the SJ300 inverter before operating with this board. When the operation command is given from the terminal side of the inverter main body, operate with the following procedure. Turn ON the POWER switch of the inverter. Set the necessary items according to the instruction manual "Chapter 4 FUNCTION EXPLANATION" of the inverter main body. For speed control, operation is started when operation command of the inverter main body is turned on. For position control, turn on the STAT terminal of SJ-FB and operation command of the inverter main body first of all. Next input the pulse train position command to SAP-SAN and SBP-SBN. Then the motor turns only the pulse that you input. Confirm the following while trial operation. The motor rotates in the correct direction. Neither abnormal vibration nor noise is recognized in the motor. If the motor doesn't accelerate normally or the inverter trips with overload, check the encoder for phase order. The normal phase order is that the waveform of phase A advances by 90° than that of phase B when the motor rotates forward. (Note 1) : The monitor signal may not be output from FM terminal of inverter main body under vector control with sensor (A044=05). Please confirm the monitor output in this case. (Note 2) : Please do not do the free run action by "RS terminal" of inverter main body. When you do this action, over current trip, or power element destruction may occur. Please use "FRS" the terminal when performing free run action. (Note 3) : If the torque limit setting (b041-b044) is enlarged, over current trip would occur at the time of the motor added burden. In this case, please adjust the torque limit setting value. (Note 4) : The motor constant data of the SJ300 series is the data at the time of base frequency 50Hz in the J1 motor made in Hitachi. [. . . ] Please refer to "Chapter 5. 2 FEED-BACK BOARD INITIAL SETTINGS". 8. 2 Causes and Countermeasures for Option Board Errors When any of the following alarms occurs, the inverter displays the alarm cause and stops. Display Item Contents Detect the line break or disconnection of the encoder line. Detect when there is an encoder failure. Detect when the specification of the encoder is not line driver output type. E61 (E71) (Note 1) E62 (E72) (Note 1) E69 (E79) (Note 1) Detect when the motor rotation speed exceeds (maximum frequency (note 2))×(over speed error detection level (P026). [. . . ]
