Position Control - Mitsubishi Electric FR-A700 Instruction Manual

Wiring

• Position control

Vector control dedicated motor (SF-V5RU, SF-THY), 12V complimentary
Positioning unit
MELSEQ-Q QD75P1
Torque limit command
*1 The pin number differs according to the encoder used.
Position control by pulse train input is properly performed even without connecting Z phase.
*2 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.
*3 Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc. (Refer to page 33.)
*4 For the complementary, set the terminating resistor selection switch to off position. (Refer to page 29.)
*5 A separate power supply of 5V/12V/15V/24V is necessary according to the encoder power specification.
*6 For terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AP, refer to page 30.
*7 Assign the function using Pr. 178 to Pr. 184, Pr. 187 to Pr. 189 (input terminal function selection).
*8 When position control is selected, terminal JOG function is made invalid and conditional position pulse train input
terminal becomes valid.
*9 Assign the function using Pr. 190 to Pr. 194 (output terminal function selection).
*10 For the fan of the 7.5kW or less dedicated motor, the power supply is single phase. (200V/50Hz, 200 to 230V/60Hz)
*11 Assign OH (external thermal input) signal to the terminal CS. (Set "7" in Pr. 186 )
Connect a 2W1kΩ resistor between the terminal PC and CS (OH). Install the
resistor pushing against the bottom part of the terminal block so as to avoid a
contact with other cables.
Refer to section 4 of the instruction manual (applied) for details of Pr. 186 CS terminal
function selection.
