Connection of motor with encoder (vector control)
• Position control
Vector control dedicated motor (SF-V5RU, SF-THY), 12V complementary
Torque limit command
The pin number differs according to the encoder used.
Position control by pulse train input is properly performed even without connecting Z phase.
Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.
Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc. (Refer to page 33.)
For the complementary, set the terminating resistor selection switch to off position. (Refer to page 29.)
A separate power supply of 5V/12V/15V/24V is necessary according to the encoder power specification.
For terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AP, refer to page 30.
Assign the function using Pr. 178 to Pr. 184, Pr. 187 to Pr. 189 (input terminal function selection).
When position control is selected, terminal JOG function is made invalid and conditional position pulse train input
terminal becomes valid.
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 chapter 4 of
terminal function selection.
