8 / 10 page 7 Signal name(abbreviation) Pinnumber(CN1A) Function PMDSA1S3P01 Pulse input(CW) 1 2 Inputs the drive pulsefor therotation inthe CW direction. Pulse input(CCW) 3 4 Inputs the drive pulsefor therotation inthe CCWdirection. Power down input(PD) 5 6 Inputting the PD signal turns off the current that flows through the stepping motor. Photo coupler input method:Internal photocoupler ON…… PD function enabled Rotation monitor output(MON) MON(collector)7 MON(collector)8 IndicatesONwhenthe exciting phase isatthe originposition. In thefull-step,outputs once forevery6pulses. ● The CW direction of the rotation of the stepping motor is the clockwise direction when viewing the stepping motor from the output axis side (flange side). The CCW direction is the counterclockwise direction when viewing the stepping motor from the output axis side (flange side). 3-phase STEPPING SYSTEMS DC input Each section nameofthe driver 1 DC source connector(CN2) ………Connect the DC source. 2 Stepping motor output connector(CN3) ………Connect the stepping motor drive line. 3 I/O signal connector(CN1A) ………Connect the I/O signal. 4 Function selection DIP switchpack(SL,F/R,A,B,C) ………Select the function depending on your specification. Function selection DIP switchpack Operation, connection, and function SL Automatic current reduction ON 100%ofcurrent rating when stopped OFF Approx.50%ofcurrent rating when stopped ・ The factory settings are shown inthe figure above. ・ Before changing the settings of the function selection DIP switches, turn off thesourceofthe PM driver. Note 1)The temperature increase inthe motor driver can be controlled by setting SL to OFF(approx. 50 % of the rated current). Note 2)TheoutputtorquewhenSL isOFF (approx.50%of therated current) isapprox. 50 %ofthatwhenSL is ON(100%ofthe ratedcurrent). 1 SL(auto current down selection) Select the auto current down function. 2 F/R selection(Note) Thisswitch is not used. Do not set ittoOFF. DIP switch Step angle Number of drive pulses per one period of phase current AB C ON ON OFF Basicstepangle 1/1(1.2°pulse) 6 ON OFF Basicstepangle 1/2(0.6°pulse) 12 OFF ON Basicstepangle 1/4(0.3°pulse) 24 OFF OFF Basicstepangle 1/8(0.15°pulse) 48 OFF OFF ON Basicstepangle 1/16(0.075°pulse) 48 ・ When the DIP switch C = ON (1/16 division),the internal circuit(stepping motor) operates at the rising edge and falling edge of the drive pulse. If thedutyratioofthe drive pulse moves outofthe adjustment significantlyby50%,operation becomes unstable. 3 ・ 4・ 5 A, B, C(step angle setting) Set the step angle System configuration I/O signal function 3 4 1 2 3 4 5 |
