Acceleration/deceleration specification register (ACMD)

This register specifies the acceleration or deceleration. The value of this register is set in units of

0.01 G in a range of 1 to 300 (1 to 012C

H

). If the specified value exceeds the maximum

acceleration or deceleration set by a parameter, an alarm will generate the moment a movement

start command is issued.

The actuator will start moving when this register is rewritten. In other words, the

acceleration/deceleration can be changed while the actuator is moving, simply by rewriting this

register.

Push-current limiting value (PPOW)

Set the current limit during push-motion operation in PPOW. Set an appropriate value by referring

to the table below.

Actuator model name

Pushable range [%]

Settable range (input value) [H]

Actuator other than

RCS2-RA13R

20 to 70

(Note)

33 to B2

RCS2-RA13R

20 to 200

33 to 1FE

Note The setting ranges may vary depending on the actuator.

[For details, refer to the IAI catalog or operation manual of each actuator.]

The actuator will start moving when this register is rewritten. In other words, the current

limiting value can be changed during push-motion operation simply by rewriting this register.
