*1
The pin number differs according to the encoder used.
Position control by pulse train input is 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.
*6
Refer to page 17 for terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AP.
*7
Assign the function using Pr. 180 to Pr. 185, Pr. 187 to Pr. 189 (input terminal function selection).
*8
For the fan of the 7.5kW or lower dedicated motor, the power supply is single phase (200V/50Hz, 200 to 230V/60Hz).
*9
Assign OH (external thermal input) signal to the terminal CS. (Pr. 186 = "7")
Connect a 2W1kΩ resistor between the terminal PC and CS (OH).
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.
*10
Pulse signal from the positioning unit can be output by either open collector or differential line
driver. Note that connection is not the same. (The figure shows the connection in case of
differential line driver. Refer to terminal description on page 50 for connection.
