*1
The pin number differs according to the encoder used.
Speed control and torque control are properly performed even without connecting Z-phase.
*2
The encoder should be coupled on the same axis with the motor shaft without any mechanical looseness.
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 12)
*4
For the complementary, set the terminating resistor selection switch to OFF position (initial status) to use. (Refer to page 10)
*5
A separate power supply of 5V/12V/15V/24V is necessary according to the encoder power specification. When the encoder
output is the differential line driver type, only 5V 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.
When performing orientation control together, an encoder and power supply can be shared.
*6
Refer to page 17 for terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AL.
*7
For the fan of the 7.5kW or lower 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 (CH).
Install the resistor pushing it against the bottom part of the terminal block so as to
avoid a contact with other cables.
Refer to the Instruction Manual of the Inverter for details of Pr. 186 CS terminal function
selection.
