Function

15

ENBS Enable

0: Disable condition(Operation Stop, Servo OFF)

1: Enable condition (normal operation)

It shows the condition of the enable switch when a teaching tool that is

equipped with an enable switch (dead man’s switch) is connected to a

model that has the enable function equipped.

(Note) It is fixed to 1 when in AUTO Mode or for a model without the enable

function being equipped.

LOAD

Load output judgment

status

0: Normal

1: Load output judgment

If a load current threshold or check range (individual zone boundaries: only

supported by PCON-CF) is set when a movement command is issued, this

bit indicates whether or not the motor current has reached the threshold

inside the check range.

This bit maintains the current value until the next position command is

received.

12

TRQS

Torque level status

0: Normal

1: Torque level achieved

This bit turns 1 when the current has reached a level corresponding to the

specified push torque during a push-motion operation.

Since this bit indicates a level, its status will change when the current level

changes.

11

MODS Teaching mode status

0: Normal operation mode

1: Teaching mode

This bit becomes 1 when the teaching mode is selected by the “teach mode

command bit” of device control register 2.

10

TEAC

Position-data load

command status

0: Normal

1: Position data load complete

Setting the “position-data load command bit” in device control register 2 to 1

will change this bit to 0. This bit will turn 1 once position data has been

written to the EEPROM successfully.

9

JOG+

Jog+ status

0: Normal

1: “Jog+” command active

This bit becomes 1 while the “jog+ command bit” of device control register 2

is selected.

8

JOG-

Jog- status

0: Normal

1: “Jog-“ command active

This bit becomes 1 while the “jog- command bit” of device control register 2

is selected.

0

PE0

Position complete 0

These bits output a position complete number as a binary value in PIO

pattern 4 or 5 (solenoid valve mode).

Each of these bits turns 1 when the actuator has completed a position

movement and become close enough to the target position by entering the

positioning band according to a position movement command (ST0 to ST7

in device control register 2).

Although the bit turns 0 once the servo is turned OFF, when the servo is

turned ON again the bit will turn 1 if the actuator is still within the positioning

band of the specified command position data.

Moreover, they will become 1 when push-motion is completed or missed in

push-motion operation.
