*1
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.
*2
Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.
*3
Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to
*4
For the complementary, set the terminating resistor selection switches in the OFF position. (Refer to
*5
A separate power supply of 5 V/12 V/15 V/24 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 same as the encoder output voltage, and connect the external power supply between PG and SD.
*6
For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8AP, refer to
*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 invalid and simple position pulse train input terminal becomes valid.
*9
Assign the function using Pr.190 to Pr.194 (Output terminal function selection).
