CiA 402 DRIVE PROFILE
• Do not issue operation commands to the same servo amplifier from two or more masters. Otherwise, the
servo motor may operate unexpectedly.
This chapter describes how to drive a servo motor in the communication. For MR-J4-_GF_(-RJ) servo amplifier, objects are
assigned according to Index of the CiA 402 drive profile. The master station (controller) can drive the servo motor by
accessing the assigned objects.
Refer to the following for details of the objects.
5.1
State machine control of the servo amplifier
Function explanation
The servo amplifier status is controlled based on the state machine below. Setting the control command (6040h) from the
master station (controller) changes the status of the slave stations (servo amplifiers). The current servo amplifier status can be
read with the control status (6041h).
