JISL

Jog/inch switching

0: Jog

1: Inching

When this bit is 0, the jog operation is selected. When this bit is 1, the inching

operation is selected.

If this bit turns 1 while the actuator is jogging, the actuator will accelerate to a

stop.

While the actuator is inching, turning this bit 0 will have no effect and the actuator

will continue with the inching operation.

The setting of this bit is not reflected in any jog/inching operation set from the

teaching tool.

MOD

Teaching mode command 0: Normal operation mode

1: Teaching mode

Changing this bit to 1 will switch the controller to the teaching mode.

TEAC

Position data load

command

0: Normal

1: Position data load command

The current position data will be written to the position number specified by the

position number specification register if 1 is written to this bit while the 11th bit of

the teach mode command is 1 (teaching mode).

The current position data is loaded to the position data line specified by the

position number specification register. If the position number under which the

data is loaded is an empty position, meaning that no data is currently set, the

data fields other than target position (such as positioning band, etc.) will be

automatically populated by the default values of the respective parameters.

Make sure that after this bit is set to 1, it will remain 1 for at least 20 ms.

JOG+

Jog+ command

0: Normal

1: Jog+ command

x

The actuator jogs in the direction opposite home as long as this bit is 1 if the

14th JISL bit is 0. The speed and acceleration/deceleration match the

specifications in user parameter No. 26 “PIO jog speed” and rated

acceleration/deceleration speed.

If this bit is set to 0 or the 8th bit of the jog-command is changed to 1, the

actuator will decelerate to a stop.

x

If a positive edge (this bit: 0 o 1) is detected for the jog+ command while the

14th JISL bit is 0, the actuator inches in the direction opposite home.

The speed, travel and acceleration/deceleration speed match the specifications

in user defined parameter No. 26 (PIO jog speed), user parameter No. 48 (PIO

inching distance) and rated jog acceleration/deceleration, respectively.

8

JOG-

Jog- command

0: Normal

1: Jog- command

x

The actuator jogs in the direction of home as long as this bit is 1 if the 14th

JISL bit is 0. The speed and acceleration/deceleration speed match the

specifications in user parameter No. 26 “PIO jog speed” and rated

acceleration/deceleration speed.

If this bit is set to 0 or the 9th bit of the jog-command is changed to 1, the

actuator will decelerate to a stop.

x

If a positive edge (this bit: 0 o 1) is detected for the jog+ command while the

14th JISL bit is 0, the actuator inches in the direction of home.

The speed, travel and acceleration/deceleration speed match the specifications

in user defined parameter No. 26 (PIO jog speed), user parameter No. 48 (PIO

inching distance) and rated jog acceleration/deceleration, respectively.

ST0

Start position 0

(If either of these bits is enabled) The actuator moves to the position of the

specified position number.

These bits are only valid when PIO patterns 4 or 5 (solenoid valve mode) is

selected. The move is started if either of the ST0 to ST7 bits is set to 1 (this bit: 0

o

1).

If a position other than the enabled start poison is selected, the alarm “085

Position No. error at moving” is generated.

You can select the signal input method as “Level” or “Edge” in user parameter

No. 27, “Movement command type.”

If multiple positions are entered at the same time, the smallest number takes the

priority.
