Deceleration specification register (DCMD)

This register specifies the deceleration during positioning. 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

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

command is issued.

„

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.]

Load Output Current Threshold (LPOW)

To perform load output judgment, set the current threshold in LPOW. Set an appropriate value

according to the actuator used, just like the push current limit (PPOW). If load output judgment

is not performed, set 0.
