
The setting is available when a Vector control compatible option is installed.

These parameters are available when a built-in option (FR-A8AP/FR-A8AL/FR-A8APR/FR-A8APS) is installed.

These parameters are available when the option (FR-A8TP) is installed.

The setting is available when the FR-A8AP/FR-A8AL is installed.

The setting is available when the FR-A8AP/FR-A8AL/FR-A8APR/FR-A8TP is installed.

To perform machine end orientation, the plug-in option (FR-A8AP/FR-A8AL/FR-A8APR/FR-A8APS) and control terminal option (FR-A8TP) are
required.

The setting is available when the FR-A8AL is installed.

When the second motor is selected, the orientation control is disabled.


The pin number differs according to the encoder used.

Use Pr.178 to Pr.189 (Input terminal function selection) to assign the function to a terminal. (Refer to

Use Pr.190 to Pr.196 (Output terminal function selection) to assign the function to a terminal. (Refer to

Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.

Connect the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to

For the differential line driver, set the terminating resistor selection switch to the ON position (initial status) to use. (Refer to
Note that the terminating resistor switch should be set to the OFF position when sharing the same encoder with another unit (NC, etc.) or when
the terminating resistor is connected to another unit. For the complementary, set the switch to the OFF position.

A separate power supply of 5 V/12 V/15 V/24 V is necessary according to the encoder power specification. Make the voltage of the external
power supply same as the encoder output voltage, and connect the external power supply between PG and SD. When performing encoder
feedback control and vector control together, an encoder and power supply can be shared.

When a stop position command is input from outside, a plug-in option FR-A8AX is required. Refer to
command.
Setting
• If the orientation command signal (X22) is turned ON during operation after the various parameters have been set, the
speed will decelerate to the "orientation switchover speed". After the "orientation stop distance" is calculated, the speed will
further decelerate, and the "orientation state" (servo lock) will be entered. The "orientation complete signal" (ORA) will be
output when the "orientation complete width" is entered.
