Program language (programmed by the setup software) Program capacity: 120 steps
Set by the program language One-point feed length setting range: ±1 (µm) to ±999.999 (mm)
A servomotor speed, acceleration and deceleration time constants,
and S-pattern acceleration and deceleration time constants are set by the program language.
The S-pattern acceleration and deceleration time constants can be set by parameter No. 14 as well.
Signed absolute value command system, and signed incremental value command system
Depends on the setting of the program language
Inches upon contact input or RS-422 (RS-232C) communication based on speed commands set by a parameter.
Manual feed by manual pulse generator.
Command pulse ratio: Selectable ✕1, ✕10, or ✕100 by the parameter.

Rated output and rated speed of the servomotor used in combination with the servo-amp are as indicated when using the power-supply voltage and frequency listed.
The output capacity and speed cannot be guaranteed when the power-supply voltage is less than specified.
For torque characteristics when combined with a servomotor, refer to “servomotor torque characteristics” in this catalog.
For products without a dynamic brake (MR-J2S-MCL-ED or MR-J2S-MCL1-ED), special compliance is possible.
