The pin number differs according to the encoder used.

Speed, control, torque control, and position control by pulse train input are available with or without the Z-phase being connected.

Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.

Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to

For the complementary, set the terminating resistor selection switch to the OFF position (initial status). (Refer to

A separate power supply of 5 V/12 V/15 V is necessary according to the encoder power specification. When the encoder output is the

differential line driver type, only 5 V can be input.

Make the voltage of the external power supply the same as the encoder output voltage, and connect the external power supply between

PG and SD.

For the 24 V encoder, 24 V power can be supplied from terminal PG24 on the FR-A8TP.

For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8TP, refer to

For the fan of the 7.5 kW or lower dedicated motor, the power supply is single phase. (200 V/50 Hz, 200 to 230 V/60 Hz)

To enable terminal OH, set Pr.876 Thermal protector input = "1 (initial value)".

Assign the function using Pr.178 to Pr.182, Pr.185, or Pr.189 (input terminal function selection).

*10 When position control is selected, terminal DI4 function is invalid and simple position pulse train input terminal becomes valid.

*11 Assign the function using Pr.190 to Pr.192, or Pr.195 (output terminal function selection).

*12 The SF-PR-SC does not have a cooling fan.

*13 Some SF-PR-SC models have a thermal protector.
