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 OFF position. (Refer to
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 the same as the encoder output voltage, and connect the external power supply across PG
and SD.
When performing orientation control together, an encoder and power supply can be shared.
For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8AP, 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)
Connect the recommended 2W1k
resistor between the terminal PC and OH. (Recommended product: MOS2C102J 2W1k
by KOA
Corporation)
Insert the input line and the resistor to a 2-wire blade terminal, and connect the blade terminal to the terminal OH. (For the recommended
2-wire blade terminals, refer to
.)
Insulate the lead wire of the resistor, for example by applying a contraction tube, and shape the wires so that the resistor and its lead wire
will not touch other cables. Caulk the lead wire securely together with the thermal protector input line using a 2-wire blade terminal.
(Do not subject the lead wire's bottom area to an excessive pressure.)
To use a terminal as the terminal OH, assign the OH (external thermal O/L relay input) signal to an input terminal. (Set "7" in any of
Pr.178
to Pr.189
. For details, refer to the Instruction Manual (Detailed) of the inverter.)
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 invalid and simple position pulse train input terminal becomes valid.
Assign the function using
Pr.190 to Pr.194 (output terminal function selection)
.
