WIRING
• Position control
Vector control dedicated motor, 12V complimentary
*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 36.)
*4 For the complementary, set the terminating resistor selection switch to off position. (Refer to page 32.)
*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 and FR-A7AP, refer to page 33.
*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).
