CHAPTER 1 INTRODUCTION 1 1.1 INSPECTION UPON UNPACKING Make sure to treat the product carefully not to give shock and vibration while unpacking. Check that the product is the one you ordered, and that there is no damage during transportation.
CHAPTER 2 INSTALLATION METHOD OF PRINTED BOARD 2 2.1 INSTALLATION METHOD OF PRINTED BOARD As the following Figure 2-1, exactly connect option board 1 or 2 to the holes of the four corners and the connector part of the back. Be sure to fit them to the guide post for positioning of option printed board and screw holes for fixing.
CHAPTER 3 WIRING, CONNECTING 3 3.1 TERMINAL ASSIGNMENT OF DIGITAL INPUT OPTION BOARD Figure 3-1a shows terminal assignment, Figure 3-1b shows terminal standard connection. In case of sink type interface , power is supplied to input terminal (D0 to D15, STRB) by short circuit between P24B terminal and PLCB terminal.
CHAPTER 3 WIRING, CONNECTION 4 3.2 CONNECTION TO PROGRAMABLE CONTROLLER In case of operating this unit connecting to programable controller, there are 4 patterns of input terminals ( Table 3-2a), 2 patterns of output terminals( Table 3-2b). Please connect fitted to the type of programable controller used.
CHAPTER 3 WIRING, CONNECTION 5 3.3 SPECIFICATION OF TERMINAL Table 3-3 shows specification of terminal. Table 3-3 Specification of terminal Terminal symbol Terminal name Specification Electric charact.
CHAPTER 4 SETTING 6 Rotary switch C ODE Dip switch T YPE Figure 4-1 Position of switch 4.1 POSITION OF SETTING SWITCH Figure 4-1shows position of setting switch . PAC, DIV, BIN, BCD which printed around the dip switch (TYPE) means one time input , 2 dividing input, binary input, BCD input.
CHAPTER 4 SETTING 7 It is possible to select input mode by combination of dip switch and rotary switch on the option printed board. Table 4-4 shows table of input mode. (Viewpoint of table of input mode) Example 1) In one time input mode, switch setting which se ts setting frequency by 1Hz resolution and binary input.
CHAPTER 4 SETTING 8 4.5 PRECAUTIONS AT SETTING OF SWITCH (1) In case of setting rotary switch code to (5, 7 to F) in one time input mode, sequence error outputs just after power on of inverter. (2) In case of setting rotary switch code to (B to F) in 2 dividing input mode, sequence error outputs just after power on of inverter.
CHAPTER 5 FUNCTION 9 Setting of dip switch TYPE 1 2 BIN PAC Setting of dip switch TYPE 1 2 BCD PAC 5.1 FUNCTION 5.1.1 ONE TIME BINARY INPUT It is possible to select frequency setting, torque limit setting or position setting of one time data input by rotary switch CODE.
CHAPTER 5 FUNCTION 10 Setting of dip switch TYPE 1 2 BIN DIV P recaution Refer to 5.3 ” DATA INPUT TIMING ” for signal input timing. 5.1.3 TWO DIVIDING BINARY INPUT It is possible to change setting data by twice input of data, higher data and lower data.
CHAPTER 5 FUNCTION 11 Setting of dip switch TYPE 1 2 BCD DIV 5.1.4 TWO DIVIDING BCD INPUT It is possible to change setting data by twice input of data, higher data and lower data.
CHAPTER 5 FUNCTION 12 5.2 CLASSIFICATION CODE Table 5.2 shows table of classification code. Make sure to input classification code in order, higher code and then lower code. 5.3 DATA INPUT TIMING 5.3.1 TIMING AT ONE TIME INPUT MO DE Take in data in on level that strobe signal.
CHAPTER 5 FUNCTION 13 5.3.2 TIMING AT TWO DIVIDING DATA INPUT Take in data in on-edge of strove signal. Let on/off time of strobe signal be more than 20ms. And let off time of strobe signal be more than 20ms, P recaution If Figure 5.3.2 timing chart is not satisfied, be careful because of possibility of taking in error data.
CHAPTER 5 FUNCTION 14 BCD 9999 However, f Hz set actually is calculated in max F M I f in = max F max frequency Hz and, value which is ignored less than is setting frequency.
