Connection of motor with encoder (vector control)
• Position control
Vector control dedicated motor (SF-V5RU, SF-THY), 12V complementary
*1 The pin number differs according to the encoder used.
Speed control, torque control, and position control by pulse train input are properly performed without the connection of
the 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 31.
*7 For the fan of the 7.5kW or less dedicated motor, the power supply is single phase. (200V/50Hz, 200 to 230V/60Hz)
*8 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 Chapter 4 of the Instruction Manual (Applied) for details of Pr. 186 CS
terminal function selection.
*9 Assign the function using Pr. 178 to Pr. 184, Pr. 187 to Pr. 189 (input terminal function
selection).
*10 When position control is selected, terminal JOG function is invalid and the simple position pulse train input terminal
becomes valid.
*11 Assign the function using Pr. 190 to Pr. 194 (output terminal function selection).
